NAME
Spreadsheet::ParseExcel - Extract information from an Excel file.SYNOPSIS
#!/usr/bin/perl -w use strict; use Spreadsheet::ParseExcel; my $parser = Spreadsheet::ParseExcel->new(); my $workbook = $parser->Parse('Book1.xls'); for my $worksheet ( $workbook->worksheets() ) { my ( $row_min, $row_max ) = $worksheet->row_range(); my ( $col_min, $col_max ) = $worksheet->col_range(); for my $row ( $row_min .. $row_max ) { for my $col ( $col_min .. $col_max ) { my $cell = $worksheet->get_cell( $row, $col ); next unless $cell; print "Row, Col = ($row, $col)\n"; print "Value = ", $cell->value(), "\n"; print "Unformatted = ", $cell->unformatted(), "\n"; print "\n"; } } }
DESCRIPTION
The Spreadsheet::ParseExcel module can be used to read information from an Excel 95-2003 file.Parser
new()
The "new()" method is used to create a new "Spreadsheet::ParseExcel" parser object.my $parser = Spreadsheet::ParseExcel->new();
As an advanced feature it is also possible to pass a call-back handler to the parser to control the parsing of the spreadsheet.
$parser = Spreadsheet::ParseExcel->new( [ CellHandler => \&cell_handler, NotSetCell => 1, ]);
The call-back can be used to ignore certain cells or to reduce memory usage. See the section ``Reducing the memory usage of Spreadsheet::ParseExcel'' for more information.
Parse($filename, [$formatter])
The Parser "Parse()" method return a ``Workbook'' object.my $parser = Spreadsheet::ParseExcel->new(); my $workbook = $parser->Parse('Book1.xls');
If an error occurs "Parse()" returns "undef".
The $filename parameter is generally the file to be parsed. However, it can also be a filehandle or a scalar reference.
The optional $formatter array ref can be an reference to a ``Formatter Class'' to format the value of cells.
ColorIdxToRGB()
The "ColorIdxToRGB()" method returns a RGB string corresponding to a specified color index. The RGB string has 6 characters, representing the RGB hex value, for example 'FF0000'. The color index is generally obtained from a FONT object.$RGB = $parser->ColorIdxToRGB($color_index);
Workbook
A "Spreadsheet::ParseExcel::Workbook" is created via the "Spreadsheet::ParseExcel" "Parse()" method:my $parser = Spreadsheet::ParseExcel->new(); my $workbook = $parser->Parse('Book1.xls');
The Workbook class has methods and properties that are outlined in the following sections.
Workbook Methods
Parse()
As a syntactic shorthand you can create a Parser and Workbook object in one go using the Workbook "Parse()" method. The following examples are equivalent:# Method 1 my $parser = Spreadsheet::ParseExcel->new(); my $workbook = $parser->Parse('Book1.xls'); # Method 2 my $workbook = Spreadsheet::ParseExcel::Workbook->Parse('Book1.xls');
worksheets()
Returns an array of ``Worksheet'' objects. This was most commonly used to iterate over the worksheets in a workbook:for my $worksheet ( $workbook->worksheets() ) { ... }
Worksheet()
The "Worksheet()" method returns a single "Worksheet" object using either its name or index:$worksheet = $workbook->Worksheet('Sheet1'); $worksheet = $workbook->Worksheet(0);
Returns "undef" if the sheet name or index doesn't exist.
Workbook Properties
A workbook object exposes a number of properties as shown below:$workbook->{Worksheet }->[$index] $workbook->{File} $workbook->{Author} $workbook->{Flg1904} $workbook->{Version} $workbook->{SheetCount} $workbook->{PrintArea }->[$index] $workbook->{PrintTitle}->[$index]
These properties are generally only of interest to advanced users. Casual users can skip this section.
$workbook->{Worksheet}->[$index]
Returns an array of ``Worksheet'' objects. This was most commonly used to iterate over the worksheets in a workbook:for my $worksheet (@{$workbook->{Worksheet}}) { ... }
It is now deprecated, use worksheets()) instead.

- If true, the value seems to be number.
- $format_index
- The index number for the cell Format object.
TextFmt($self, $string_data, $string_encoding)
Converts the string data in the cell into the correct encoding. It is passed the following parameters:- $self
- A scalar reference to the Formatter object.
- $string_data
- The original string/text data.
- $string_encoding
- The character encoding of original string/text.
ValFmt($self, $cell, $workbook)
Convert the original unformatted cell value into the appropriate formatted value. For instance turn a number into a formatted date. It is passed the following parameters:- $self
- A scalar reference to the Formatter object.
- $cell
- A scalar reference to the Cell object.
- $workbook
- A scalar reference to the Workbook object.
FmtString($self, $cell, $workbook)
Get the format string for the Cell. It is passed the following parameters:- $self
- A scalar reference to the Formatter object.
- $cell
- A scalar reference to the Cell object.
- $workbook
- A scalar reference to the Workbook object.
Reducing the memory usage of Spreadsheet::ParseExcel
In some cases a "Spreadsheet::ParseExcel" application may consume a lot of memory when processing a large Excel file and, as a result, may fail to complete. The following explains why this can occur and how to resolve it."Spreadsheet::ParseExcel" processes an Excel file in two stages. In the first stage it extracts the Excel binary stream from the OLE container file using "OLE::Storage_Lite". In the second stage it parses the binary stream to read workbook, worksheet and cell data which it then stores in memory. The majority of the memory usage is required for storing cell data.
The reason for this is that as the Excel file is parsed and each cell is encountered a cell handling function creates a relatively large nested cell object that contains the cell value and all of the data that relates to the cell formatting. For large files (a 10MB Excel file on a 256MB system) this overhead can cause the system to grind to a halt.
However, in a lot of cases when an Excel file is being processed the only information that is required are the cell values. In these cases it is possible to avoid most of the memory overhead by specifying your own cell handling function and by telling Spreadsheet::ParseExcel not to store the parsed cell data. This is achieved by passing a cell handler function to "new()" when creating the parse object. Here is an example.
#!/usr/bin/perl -w use strict; use Spreadsheet::ParseExcel; my $parser = Spreadsheet::ParseExcel->new( CellHandler => \&cell_handler, NotSetCell => 1 ); my $workbook = $parser->Parse('file.xls'); sub cell_handler { my $workbook = $_[0]; my $sheet_index = $_[1]; my $row = $_[2]; my $col = $_[3]; my $cell = $_[4]; # Do something useful with the formatted cell value print $cell->value(), "\n"; }
The user specified cell handler is passed as a code reference to "new()" along with the parameter "NotSetCell" which tells Spreadsheet::ParseExcel not to store the parsed cell. Note, you don't have to iterate over the rows and columns, this happens automatically as part of the parsing.
The cell handler is passed 5 arguments. The first, $workbook, is a reference to the "Spreadsheet::ParseExcel::Workbook" object that represent the parsed workbook. This can be used to access any of the "Spreadsheet::ParseExcel::Workbook" methods, see ``Workbook''. The second $sheet_index is the zero-based index of the worksheet being parsed. The third and fourth, $row and $col, are the zero-based row and column number of the cell. The fifth, $cell, is a reference to the "Spreadsheet::ParseExcel::Cell" object. This is used to extract the data from the cell. See ``Cell'' for more information.
This technique can be useful if you are writing an Excel to database filter since you can put your DB calls in the cell handler.
If you don't want all of the data in the spreadsheet you can add some control logic to the cell handler. For example we can extend the previous example so that it only prints the first 10 rows of the first two worksheets in the parsed workbook by adding some "if()" statements to the cell handler:
#!/usr/bin/perl -w use strict; use Spreadsheet::ParseExcel; my $parser = Spreadsheet::ParseExcel->new( CellHandler => \&cell_handler, NotSetCell => 1 ); my $workbook = $parser->Parse('file.xls'); sub cell_handler { my $workbook = $_[0]; my $sheet_index = $_[1]; my $row = $_[2]; my $col = $_[3]; my $cell = $_[4]; # Skip some worksheets and rows (inefficiently). return if $sheet_index >= 3; return if $row >= 10; # Do something with the formatted cell value print $cell->value(), "\n"; }
However, this still processes the entire workbook. If you wish to save some additional processing time you can abort the parsing after you have read the data that you want, using the workbook "ParseAbort" method:
#!/usr/bin/perl -w use strict; use Spreadsheet::ParseExcel; my $parser = Spreadsheet::ParseExcel->new( CellHandler => \&cell_handler, NotSetCell => 1 ); my $workbook = $parser->Parse('file.xls'); sub cell_handler { my $workbook = $_[0]; my $sheet_index = $_[1]; my $row = $_[2]; my $col = $_[3]; my $cell = $_[4]; # Skip some worksheets and rows (more efficiently). if ( $sheet_index >= 1 and $row >= 10 ) { $workbook->ParseAbort(1); return; } # Do something with the formatted cell value print $cell->value(), "\n"; }
KNOWN PROBLEMS
- *
- Issues reported by users: http://rt.cpan.org/Public/Dist/Display.html?Name=Spreadsheet-ParseExcel
- *
- This module cannot read the values of formulas from files created with Spreadsheet::WriteExcel unless the user specified the values when creating the file (which is generally not the case). The reason for this is that Spreadsheet::WriteExcel writes the formula but not the formula result since it isn't in a position to calculate arbitrary Excel formulas without access to Excel's formula engine.
- *
- If Excel has date fields where the specified format is equal to the system-default for the short-date locale, Excel does not store the format, but defaults to an internal format which is system dependent. In these cases ParseExcel uses the date format 'yyyy-mm-dd'.
