NAME

Spreadsheet::Read - Read the data from a spreadsheet

SYNOPSIS

use Spreadsheet::Read;
my $book  = ReadData ("test.csv", sep => ";");
my $book  = ReadData ("test.sxc");
my $book  = ReadData ("test.ods");
my $book  = ReadData ("test.xls");
my $book  = ReadData ("test.xlsx");
my $book  = ReadData ("test.xlsm");
my $book  = ReadData ($fh, parser => "xls");

Spreadsheet::Read::add ($book, "sheet.csv");

my $sheet = $book->[1];             # first datasheet
my $cell  = $book->[1]{A3};         # content of field A3 of sheet 1
my $cell  = $book->[1]{cell}[1][3]; # same, unformatted

# OO API
my $book = Spreadsheet::Read->new ("file.csv");
my $sheet = $book->sheet (1);
my $cell  = $sheet->cell ("A3");
my $cell  = $sheet->cell (1, 3);

$book->add ("test.xls");

DESCRIPTION

Spreadsheet::Read tries to transparently read *any* spreadsheet and return its content in a universal manner independent of the parsing module that does the actual spreadsheet scanning.

For OpenOffice and/or LibreOffice this module uses Spreadsheet::ReadSXC

For Microsoft Excel this module uses Spreadsheet::ParseExcel, Spreadsheet::ParseXLSX, or Spreadsheet::XLSX (stronly discouraged).

For CSV this module uses Text::CSV_XS or Text::CSV_PP.

For SquirrelCalc there is a very simplistic built-in parser

Data structure

The data is returned as an array reference:

$book = [
    # Entry 0 is the overall control hash
    { sheets  => 2,
      sheet   => {
        "Sheet 1" => 1,
        "Sheet 2" => 2,
        },
      parsers => [ {
        type      => "xls",
        parser    => "Spreadsheet::ParseExcel",
        version   => 0.59,
        }],
      error   => undef,
      },
    # Entry 1 is the first sheet
    { parser  => 0,
      label   => "Sheet 1",
      maxrow  => 2,
      maxcol  => 4,
      cell    => [ undef,
        [ undef, 1 ],
        [ undef, undef, undef, undef, undef, "Nugget" ],
        ],
      attr    => [],
      merged  => [],
      active  => 1,
      A1      => 1,
      B5      => "Nugget",
      },
    # Entry 2 is the second sheet
    { parser  => 0,
      label   => "Sheet 2",
      :
      :

To keep as close contact to spreadsheet users, row and column 1 have index 1 too in the cell element of the sheet hash, so cell "A1" is the same as cell [1, 1] (column first). To switch between the two, there are helper functions available: cell2cr (), cr2cell (), and col2label ().

The cell hash entry contains unformatted data, while the hash entries with the traditional labels contain the formatted values (if applicable).

The control hash (the first entry in the returned array ref), contains some spreadsheet meta-data. The entry sheet is there to be able to find the sheets when accessing them by name:

my %sheet2 = %{$book->[$book->[0]{sheet}{"Sheet 2"}]};

Formatted vs Unformatted

The difference between formatted and unformatted cells is that the (optional) format is applied to the cell or not. This part is completely implemented on the parser side. Spreadsheet::Read just makes both available if these are supported. Options provide means to disable either. If the parser does not provide formatted cells - like CSV - both values are equal.

To show what this implies:

use Spreadsheet::Read;

my $file     = "files/example.xlsx";
my $workbook = Spreadsheet::Read->new ($file);

my $info     = $workbook->[0];
say "Parsed $file with $info->{parser}-$info->{version}";

my $sheet    = $workbook->sheet (1);

say join "\t" => "Formatted:",   $sheet->row     (1);
say join "\t" => "Unformatted:", $sheet->cellrow (1);

Might return very different results depending one the underlying parser (and its version):

Parsed files/example.xlsx with Spreadsheet::ParseXLSX-0.27
Formatted:      8-Aug   Foo & Barr < Quux
Unformatted:    39668   Foo & Barr < Quux

Parsed files/example.xlsx with Spreadsheet::XLSX-0.15
Formatted:      39668   Foo &amp; Barr &lt; Quux
Unformatted:    39668   Foo &amp; Barr &lt; Quux

Functions and methods

new

my $book = Spreadsheet::Read->new (...) or die $@;

All options accepted by ReadData are accepted by new.

With no arguments at all, $book will be an object where sheets can be added using add

my $book = Spreadsheet::Read->new ();
$book->add ("file.csv");
$book->add ("file.cslx");

ReadData

my $book = ReadData ($source [, option => value [, ... ]]);

my $book = ReadData ("file.csv", sep => ',', quote => '"');

my $book = ReadData ("file.xls", dtfmt => "yyyy-mm-dd");

my $book = ReadData ("file.ods");

my $book = ReadData ("file.sxc");

my $book = ReadData ("content.xml");

my $book = ReadData ($content);

my $book = ReadData ($content,  parser => "xlsx");

my $book = ReadData ($fh,       parser => "xlsx");

my $book = ReadData (\$content, parser => "xlsx");

Tries to convert the given file, string, or stream to the data structure described above.

Processing Excel data from a stream or content is supported through a File::Temp temporary file or IO::Scalar when available.

Spreadsheet::ReadSXC does preserve sheet order as of version 0.20.

Choosing between $content and \\$content (with or without passing the desired parser option) may be depending on trial and terror. ReadData does try to determine parser type on content if needed, but not all combinations are checked, and not all signatures are builtin.

Currently supported options are:

parser

Force the data to be parsed by a specific format. Possible values are csv, prl (or perl), sc (or squirrelcalc), sxc (or oo, ods, openoffice, libreoffice) xls (or excel), and xlsx (or excel2007).

When parsing streams, instead of files, it is highly recommended to pass this option.

Spreadsheet::Read supports several underlying parsers per spreadsheet type. It will try those from most favored to least favored. When you have a good reason to prefer a different parser, you can set that in environment variables. The other options then will not be tested for:

env SPREADSHEET_READ_CSV=Text::CSV_PP ...

cells

Control the generation of named cells ("A1" etc). Default is true.

rc

Control the generation of the {cell}[c][r] entries. Default is true.

attr

Control the generation of the {attr}[c][r] entries. Default is false. See "Cell Attributes" below.

clip

If set, ReadData will remove all trailing rows and columns per sheet that have no data, where no data means only undefined or empty cells (after optional stripping). If a sheet has no data at all, the sheet will be skipped entirely when this attribute is true.

strip

If set, ReadData will remove trailing- and/or leading-whitespace from every field.

strip  leading  strailing
-----  -------  ---------
  0      n/a      n/a
  1     strip     n/a
  2      n/a     strip
  3     strip    strip

pivot

Swap all rows and columns.

When a sheet contains data like

A1  B1  C1      E1
A2      C2  D2
A3  B3  C3  D3  E3

using pivot will return the sheet data as

A1  A2  A3
B1      B3
C1  C2  C3
    D2  D3
E1      E3

sep

Set separator for CSV. Default is comma ,.

quote

Set quote character for CSV. Default is ".

dtfmt

Set the format for MS-Excel date fields that are set to use the default date format. The default format in Excel is "m-d-yy", which is both not year 2000 safe, nor very useful. The default is now "yyyy-mm-dd", which is more ISO-like.

Note that date formatting in MS-Excel is not reliable at all, as it will store/replace/change the date field separator in already stored formats if you change your locale settings. So the above mentioned default can be either "m-d-yy" OR "m/d/yy" depending on what that specific character happened to be at the time the user saved the file.

merge

Copy content to all cells in merged areas.

If supported, this will copy formatted and unformatted values from the top-left cell of a merged area to all other cells in the area.

debug

Enable some diagnostic messages to STDERR.

The value determines how much diagnostics are dumped (using Data::Peek). A value of 9 and higher will dump the entire structure from the back-end parser.

passwd

Use this password to decrypt password protected spreadsheet.

Currently only supports Excel.

All other attributes/options will be passed to the underlying parser if that parser supports attributes.

col2label

my $col_id = col2label (col);

my $col_id = $book->col2label (col);  # OO

col2label () converts a (column) (1 based) to the letters used in the traditional cell notation:

my $id = col2label ( 4); # $id now "D"
my $id = col2label (28); # $id now "AB"

cr2cell

my $cell = cr2cell (col, row);

my $cell = $book->cr2cell (col, row);  # OO

cr2cell () converts a (column, row) pair (1 based) to the traditional cell notation:

my $cell = cr2cell ( 4, 14); # $cell now "D14"
my $cell = cr2cell (28,  4); # $cell now "AB4"

cell2cr

my ($col, $row) = cell2cr ($cell);

my ($col, $row) = $book->cell2cr ($cell);  # OO

cell2cr () converts traditional cell notation to a (column, row) pair (1 based):

my ($col, $row) = cell2cr ("D14"); # returns ( 4, 14)
my ($col, $row) = cell2cr ("AB4"); # returns (28,  4)

row

my @row = row ($sheet, $row)

my @row = Spreadsheet::Read::row ($book->[1], 3);

my @row = $book->row ($sheet, $row); # OO

Get full row of formatted values (like $sheet->{A3} .. $sheet->{G3})

Note that the indexes in the returned list are 0-based.

row () is not imported by default, so either specify it in the use argument list, or call it fully qualified.

cellrow

my @row = cellrow ($sheet, $row);

my @row = Spreadsheet::Read::cellrow ($book->[1], 3);

my @row = $book->cellrow ($sheet, $row); # OO

Get full row of unformatted values (like $sheet->{cell}[1][3] .. $sheet->{cell}[7][3])

Note that the indexes in the returned list are 0-based.

cellrow () is not imported by default, so either specify it in the use argument list, or call it fully qualified or as method call.

See also the cellrow () method on sheets.

rows

my @rows = rows ($sheet);

my @rows = Spreadsheet::Read::rows ($book->[1]);

my @rows = $book->rows (1); # OO

Convert {cell}'s [column][row] to a [row][column] list.

Note that the indexes in the returned list are 0-based, where the index in the {cell} entry is 1-based.

rows () is not imported by default, so either specify it in the use argument list, or call it fully qualified.

parses

parses ($format);

Spreadsheet::Read::parses ("CSV");

$book->parses ("CSV"); # OO

parses () returns Spreadsheet::Read's capability to parse the required format. ReadData will pick its preferred parser for that format unless overruled. See parser.

parses () is not imported by default, so either specify it in the use argument list, or call it fully qualified.

If $format is false (undef, "", or 0), parses () will return a sorted list of supported types.

@my types = parses ("");   # e.g: csv, ods, sc, sxc, xls, xlsx

parsers

my @p = parsers ();

parsers () returns a list of hashrefs with information about supported parsers, each giving information about the parser, its versions and if it will be used as default parser for the given type, like:

{ ext => "csv",            # extension or type
  mod => "Text::CSV_XS",   # parser module
  min => "0.71",           # module required  version
  vsn => "1.45",           # module installed version
  def => "*",              # is default for ext
  }

As the modules are actually loaded to get their version, do only use this to analyse prerequisites.

Version

my $v = Version ()

my $v = Spreadsheet::Read::Version ()

my $v = Spreadsheet::Read->VERSION;

my $v = $book->Version (); # OO

Returns the current version of Spreadsheet::Read.

Version () is not imported by default, so either specify it in the use argument list, or call it fully qualified.

This function returns exactly the same as Spreadsheet::Read->VERSION returns and is only kept for backward compatibility reasons.

sheets

my $sheets = $book->sheets; # OO
my @sheets = $book->sheets; # OO

In scalar context return the number of sheets in the book. In list context return the labels of the sheets in the book.

sheet

my $sheet = $book->sheet (1);     # OO
my $sheet = $book->sheet ("Foo"); # OO

Return the numbered or named sheet out of the book. Will return undef if there is no match. Will not work for sheets named with a number between 1 and the number of sheets in the book.

With named sheets will first try to use the list of sheet-labels as stored in the control structure. If no match is found, it will scan the actual labels of the sheets. In that case, it will return the first matching sheet.

If defined, the returned sheet will be of class Spreadsheet::Read::Sheet.

add

my $book = ReadData ("file.csv");
Spreadsheet::Read::add ($book, "file.xlsx");

my $book = Spreadsheet::Read->new ("file.csv");
$book->add ("file.xlsx"); # OO

Methods on sheets

maxcol

my $col = $sheet->maxcol;

Return the index of the last in-use column in the sheet. This index is 1-based.

maxrow

my $row = $sheet->maxrow;

Return the index of the last in-use row in the sheet. This index is 1-based.

cell

my $cell = $sheet->cell ("A3");
my $cell = $sheet->cell (1, 3);

Return the value for a cell. Using tags will return the formatted value, using column and row will return unformatted value.

attr

my $cell = $sheet->attr ("A3");
my $cell = $sheet->attr (1, 3);

Return the attributes of a cell. Only valid if attributes are enabled through option attr.

col2label

my $col_id = $sheet->col2label (col);

col2label () converts a (column) (1 based) to the letters used in the traditional cell notation:

my $id = $sheet->col2label ( 4); # $id now "D"
my $id = $sheet->col2label (28); # $id now "AB"

cr2cell

my $cell = $sheet->cr2cell (col, row);

cr2cell () converts a (column, row) pair (1 based) to the traditional cell notation:

my $cell = $sheet->cr2cell ( 4, 14); # $cell now "D14"
my $cell = $sheet->cr2cell (28,  4); # $cell now "AB4"

cell2cr

my ($col, $row) = $sheet->cell2cr ($cell);

cell2cr () converts traditional cell notation to a (column, row) pair (1 based):

my ($col, $row) = $sheet->cell2cr ("D14"); # returns ( 4, 14)
my ($col, $row) = $sheet->cell2cr ("AB4"); # returns (28,  4)

col

my @col = $sheet->column ($col);

Get full column of formatted values (like $sheet->{C1} .. $sheet->{C9})

Note that the indexes in the returned list are 0-based.

cellcolumn

my @col = $sheet->cellcolumn ($col);

Get full column of unformatted values (like $sheet->{cell}[3][1] .. $sheet->{cell}[3][9])

Note that the indexes in the returned list are 0-based.

row

my @row = $sheet->row ($row);

Get full row of formatted values (like $sheet->{A3} .. $sheet->{G3})

Note that the indexes in the returned list are 0-based.

cellrow

my @row = $sheet->cellrow ($row);

Get full row of unformatted values (like $sheet->{cell}[1][3] .. $sheet->{cell}[7][3])

Note that the indexes in the returned list are 0-based.

rows

my @rows = $sheet->rows ();

Convert {cell}'s [column][row] to a [row][column] list.

Note that the indexes in the returned list are 0-based, where the index in the {cell} entry is 1-based.

merged_from

my $top_left = $sheet->merged_from ("C2");
my $top_left = $sheet->merged_from (3, 2);

If the parser supports merged areas, this method will return the label of the top-left cell in the merged area the requested cell is part of.

If the requested ID is valid and withing the sheet cell range, but not part of a merged area, it will return "".

If the ID is not valid or out of range, it returns undef.

See Merged cells for more details.

label

my $label = $sheet->label;
$sheet->label ("New sheet label");

Set a new label to a sheet. Note that the index in the control structure will NOT be updated.

active

my $sheet_is_active = $sheet->active;

Returns 1 if the selected sheet is active, otherwise returns 0.

Currently only works on XLS (as of Spreadsheed::ParseExcel-0.61). CSV is always active.

Using CSV

In case of CSV parsing, ReadData will use the first line of the file to auto-detect the separation character if the first argument is a file and both sep and quote are not passed as attributes. Text::CSV_XS (or Text::CSV_PP) is able to automatically detect and use \r line endings.

CSV can parse streams too, but be sure to pass sep and/or quote if these do not match the default , and ".

When an error is found in the CSV, it is automatically reported (to STDERR). The structure will store the error in $ss->[0]{error} as anonymous list returned by $csv->error_diag. See Text::CSV_XS for documentation.

my $ss = ReadData ("bad.csv");
$ss->[0]{error} and say $ss->[0]{error}[1];

As CSV has no sheet labels, the default label for a CSV sheet is its filename. For CSV, this can be overruled using the label attribute:

my $ss = Spreadsheet::Read->new ("/some/place/test.csv", label => "Test");

Cell Attributes

If the constructor was called with attr having a true value,

my $book = ReadData ("book.xls", attr => 1);
my $book = Spreadsheet::Read->new ("book.xlsx", attr => 1);

effort is made to analyze and store field attributes like this:

    { label  => "Sheet 1",
      maxrow => 5,
      maxcol => 2,
      cell   => [ undef,
	[ undef, 1 ],
	[ undef, undef, undef, undef, undef, "Nugget" ],
	],
      attr   => [ undef,
	[ undef, {
	  type    => "numeric",
	  fgcolor => "#ff0000",
	  bgcolor => undef,
	  font    => "Arial",
	  size    => undef,
	  format  => "## ##0.00",
	  halign  => "right",
	  valign  => "top",
	  uline   => 0,
	  bold    => 0,
	  italic  => 0,
	  wrap    => 0,
	  merged  => 0,
	  hidden  => 0,
	  locked  => 0,
	  enc     => "utf-8",
	  }, ],
	[ undef, undef, undef, undef, undef, {
	  type    => "text",
	  fgcolor => "#e2e2e2",
	  bgcolor => undef,
	  font    => "Letter Gothic",
	  size    => 15,
	  format  => undef,
	  halign  => "left",
	  valign  => "top",
	  uline   => 0,
	  bold    => 0,
	  italic  => 0,
	  wrap    => 0,
	  merged  => 0,
	  hidden  => 0,
	  locked  => 0,
	  enc     => "iso8859-1",
	  }, ],
	],
      merged => [],
      A1     => 1,
      B5     => "Nugget",
      },

The entries maxrow and maxcol are 1-based.

This has now been partially implemented, mainly for Excel, as the other parsers do not (yet) support all of that. YMMV.

If a cell itself is not hidden, but the parser holds the information that either the row or the column (or both) the field is in is hidden, the flag is inherited into the cell attributes.

You can get the attributes of a cell (as a hash-ref) like this:

my $attr = $book[1]{attr}[1][3];          # Direct structure
my $attr = $book->sheet (1)->attr (1, 3); # Same using OO
my $attr = $book->sheet (1)->attr ("A3"); # Same using OO

To get to the font attribute, use any of these:

my $font = $book[1]{attr}[1][3]{font};
my $font = $book->sheet (1)->attr (1, 3)->{font};
my $font = $book->sheet (1)->attr ("A3")->font;

Merged cells

Note that only Spreadsheet::ReadSXC documents the use of merged cells, and not in a way useful for the spreadsheet consumer.

CSV does not support merged cells (though future implementations of CSV for the web might).

The documentation of merged areas in Spreadsheet::ParseExcel and Spreadsheet::ParseXLSX can be found in Spreadsheet::ParseExcel::Worksheet and Spreadsheet::ParseExcel::Cell.

None of basic Spreadsheet::XLSX, Spreadsheet::ParseExcel, and Spreadsheet::ParseXLSX manual pages mention merged cells at all.

This module just tries to return the information in a generic way.

Given this spreadsheet as an example

merged.xlsx:

    A     B     C
 +-----+-----------+
1|     | foo       |
 +-----+           +
2| bar |           |
 |     +-----+-----+
3|     | urg | orc |
 +-----+-----+-----+

the information extracted from that undocumented information is returned in the merged entry of the sheet's hash as a list of top-left, bottom-right coordinate pars (col, row, col, row). For given example, that would be:

$ss->{merged} = [
   [ 1, 2, 1, 3 ], # A2-A3
   [ 2, 1, 3, 2 ], # B1-C2
   ];

To find the label of the top-left cell in a merged area, use the merged_from method.

$ss->merged_from ("C2"); # will return "B1"

When the attributes are also enabled, there is some merge information copied directly from the cell information, but again, that stems from code analysis and not from documentation:

my $ss = ReadData ("merged.xlsx", attr => 1)->[1];
foreach my $row (1 .. $ss->{maxrow}) {
    foreach my $col (1 .. $ss->{maxcol}) {
        my $cell = cr2cell ($col, $row);
        printf "%s %-3s %s  ", $cell, $ss->{$cell},
            $ss->{attr}[$col][$row]{merged};
        }
    print "\n";
    }

A1     0  B1 foo 1  C1     1
A2 bar 1  B2     1  C2     1
A3     1  B3 urg 0  C3 orc 0

In this example, there is no way to see if B2 is merged to A2 or to B1 without analyzing all surrounding cells. This could as well mean A2:A3, B1:C1, B2:C2, as A2:A3, B1:B2, C1:C2, as A2:A3, B1:C2.

Use the merged entry described above to find out what fields are merged to what other fields or use merge:

my $ss = ReadData ("merged.xlsx", attr => 1, merge => 1)->[1];
foreach my $row (1 .. $ss->{maxrow}) {
    foreach my $col (1 .. $ss->{maxcol}) {
        my $cell = cr2cell ($col, $row);
        printf "%s %-3s %s  ", $cell, $ss->{$cell},
            $ss->{attr}[$col][$row]{merged};
        }
    print "\n";
    }

A1     0   B1 foo B1  C1 foo B1
A2 bar A2  B2 foo B1  C2 foo B1
A3 bar A2  B3 urg 0   C3 orc 0

Streams from web-resources

If you want to stream a web-resource, and the underlying parser supports it, you could use a helper function like this (thanks Corion):

use HTTP::Tiny;
use Spreadsheet::Read;

# Fetch data and return a filehandle to that data
sub fh_from_url {
    my $url = shift;
    my $ua  = HTTP::Tiny->new;
    my $res = $ua->get ($url);
    open my $fh, "<", \$res->{content};
    return $fh
    } # fh_from_url

my $fh = fh_from_url ("http://example.com/example.csv");
my $sheet = Spreadsheet::Read->new ($fh, parser => "csv");

TOOLS

This modules comes with a few tools that perform tasks from the FAQ, like "How do I select only column D through F from sheet 2 into a CSV file?"

`xls2csv`

Convert a spreadsheet to CSV. This is identical to xlsx2csv

`ss2tk`

TODO

Options

Module Options: New Spreadsheet::Read options are bound to happen. I'm thinking of an option that disables the reading of the data entirely to speed up an index request (how many sheets/fields/columns). See xlscat -i.
Parser options: Try to transparently support as many options as the encapsulated modules support regarding (un)formatted values, (date) formats, hidden columns rows or fields etc. These could be implemented like attr above but names meta, or just be new values in the attr hashes.

Other parsers

Add support for new(er) parsers for already supported formats, like

Data::XLSX::Parser

Data::XLSX::Parser provides faster way to parse Microsoft Excel's .xlsx files. The implementation of this module is highly inspired from Python's FastXLSX library.

This is SAX based parser, so you can parse very large XLSX file with lower memory usage.

Other spreadsheet formats

I consider adding any spreadsheet interface that offers a usable API.

Under investigation:

Gnumeric (.gnumeric)

I have seen no existing CPAN module yet.

It is gzip'ed XML

Kspread (.ksp)

Now knows as Calligra Sheets.

I have seen no existing CPAN module yet.

It is XML in ZIP

Alternative parsers for existing formats

As long as the alternative has a good reason for its existence, and the API of that parser reasonable fits in my approach, I will consider to implement the glue layer, or apply patches to do so as long as these match what CONTRIBUTING.md describes.
