DESCRIPTION
The Spreadsheet::ParseExcel module can be used to read information from
Excel 95-2003 binary files.
The module cannot read files in the Excel 2007 Open XML XLSX format.
See the Spreadsheet::XLSX module instead.
Parsernew()
The "new()" method is used to create a new "Spreadsheet::ParseExcel"
parser object.
my $parser = Spreadsheet::ParseExcel->new();
It it possible to pass a password to decrypt an encrypted file:
$parser = Spreadsheet::ParseExcel->new( Password => 'secret' );
Only the default Excel encryption scheme is currently supported. See
"Decryption".
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 returns a "Workbook" object.
my $parser = Spreadsheet::ParseExcel->new();
my $workbook = $parser->parse('Book1.xls');
If an error occurs "parse()" returns "undef". In general, programs
should contain a test for failed parsing as follows:
my $parser = Spreadsheet::ParseExcel->new();
my $workbook = $parser->parse('Book1.xls');
if ( !defined $workbook ) {
die $parser->error(), ".\n";
}
The $filename parameter is generally the file to be parsed. However, it
can also be a filehandle or a scalar reference.
The optional $formatter parameter can be an reference to a "Formatter
Class" to format the value of cells. This is useful for parsing
workbooks with Unicode or Asian characters:
my $parser = Spreadsheet::ParseExcel->new();
my $formatter = Spreadsheet::ParseExcel::FmtJapan->new();
my $workbook = $parser->parse( 'Book1.xls', $formatter );
The Spreadsheet::ParseExcel::FmtJapan formatter also supports Unicode.
If you encounter any encoding problems with the default formatter try
that instead.
error()
The Parser "error()" method returns an error string if a "parse()"
fails:
my $parser = Spreadsheet::ParseExcel->new();
my $workbook = $parser->parse('Book1.xls');
if ( !defined $workbook ) {
die $parser->error(), ".\n";
}
If you wish to generate you own error string you can use the
"error_code()" method instead (see below). The "error()" and
"error_code()" values are as follows:
error()error_code()
======= ============
'' 0
'File not found' 1
'No Excel data found in file' 2
'File is encrypted' 3
The "error_code()" method is explained below.
Spreadsheet::ParseExcel will try to decrypt an encrypted Excel file
using the default password or a user supplied password passed to
"new()", see above. If these fail the module will return the 'File is
encrypted' error. Only the default Excel encryption scheme is currently
supported, see "Decryption".
error_code()
The Parser "error_code()" method returns an error code if a "parse()"
fails:
my $parser = Spreadsheet::ParseExcel->new();
my $workbook = $parser->parse('Book1.xls');
if ( !defined $workbook ) {
die "Got error code ", $parser->error_code, ".\n";
}
This can be useful if you wish to employ you own error strings or error
handling methods.
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 main methods of the Workbook class are:
$workbook->worksheets()
$workbook->worksheet()
$workbook->worksheet_count()
$workbook->get_filename()
These more commonly used methods of the Workbook class are outlined
below. The other, less commonly used, methods are documented in
Spreadsheet::ParseExcel::Worksheet.
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.
worksheet_count()
The "worksheet_count()" method returns the number of Worksheet objects
in the Workbook.
my $worksheet_count = $workbook->worksheet_count();
get_filename()
The "get_filename()" method returns the name of the Excel file of
"undef" if the data was read from a filehandle rather than a file.
my $filename = $workbook->get_filename();
Other Workbook Methods
For full documentation of the methods available via a Workbook object
see Spreadsheet::ParseExcel::Workbook.
Worksheet
The "Spreadsheet::ParseExcel::Worksheet" class encapsulates the
properties of an Excel worksheet.
A Worksheet object is obtained via the "worksheets()" or "worksheet()"
methods.
for my $worksheet ( $workbook->worksheets() ) {
...
}
# Or:
$worksheet = $workbook->worksheet('Sheet1');
$worksheet = $workbook->worksheet(0);
The most commonly used methods of the Worksheet class are:
$worksheet->get_cell()
$worksheet->row_range()
$worksheet->col_range()
$worksheet->get_name()
The Spreadsheet::ParseExcel::Worksheet class exposes a lot of methods
but in general very few are required unless you are writing an advanced
filter.
The most commonly used methods are detailed below. The others are
documented in Spreadsheet::ParseExcel::Worksheet.
get_cell($row, $col)
Return the "Cell" object at row $row and column $col if it is defined.
Otherwise returns undef.
my $cell = $worksheet->get_cell($row, $col);
row_range()
Returns a two-element list "($min, $max)" containing the minimum and
maximum defined rows in the worksheet. If there is no row defined $max
is smaller than $min.
my ( $row_min, $row_max ) = $worksheet->row_range();
col_range()
Returns a two-element list "($min, $max)" containing the minimum and
maximum of defined columns in the worksheet. If there is no column
defined $max is smaller than $min.
my ( $col_min, $col_max ) = $worksheet->col_range();
get_name()
The "get_name()" method returns the name of the worksheet, such as
'Sheet1'.
my $name = $worksheet->get_name();
Other Worksheet Methods
For other, less commonly used, Worksheet methods see
Spreadsheet::ParseExcel::Worksheet.
Cell
The "Spreadsheet::ParseExcel::Cell" class has the following main
methods.
$cell->value()
$cell->unformatted()value()
The "value()" method returns the formatted value of the cell.
my $value = $cell->value();
Formatted in this sense refers to the numeric format of the cell value.
For example a number such as 40177 might be formatted as 40,117,
40117.000 or even as the date 2009/12/30.
If the cell doesn't contain a numeric format then the formatted and
unformatted cell values are the same, see the "unformatted()" method
below.
For a defined $cell the "value()" method will always return a value.
In the case of a cell with formatting but no numeric or string contents
the method will return the empty string ''.
unformatted()
The "unformatted()" method returns the unformatted value of the cell.
my $unformatted = $cell->unformatted();
Returns the cell value without a numeric format. See the "value()"
method above.
Other Cell Methods
For other, less commonly used, Worksheet methods see
Spreadsheet::ParseExcel::Cell.

$is_numeric
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

$workbook
A scalar reference to the Workbook object.
FmtString($self, $cell, $workbook)
Get the format string for the Cell. It is passed the following
parameters:

$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";
}
Decryption
If a workbook is "protected" then Excel will encrypt the file whether a
password is supplied or not. As of version 0.59 Spreadsheet::ParseExcel
supports decrypting Excel workbooks using a default or user supplied
password. However, only the following encryption scheme is supported:
Office 97/2000 Compatible encryption
The following encryption methods are not supported:
Weak Encryption (XOR)
RC4, Microsoft Base Cryptographic Provider v1.0
RC4, Microsoft Base DSS and Diffie-Hellman Cryptographic Provider
RC4, Microsoft DH SChannel Cryptographic Provider
RC4, Microsoft Enhanced Cryptographic Provider v1.0
RC4, Microsoft Enhanced DSS and Diffie-Hellman Cryptographic Provider
RC4, Microsoft Enhanced RSA and AES Cryptographic Provider
RC4, Microsoft RSA SChannel Cryptographic Provider
RC4, Microsoft Strong Cryptographic Provider

KNOWN PROBLEMS
· Issues reported by users:
http://rt.cpan.org/Public/Dist/Display.html?Name=Spreadsheet-ParseExcel
<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'.

documentation more useful, improving and simplifying the API, and
improving the maintainability of the code base. After that new
features will be added.
· Fix open bugs and documentation for SaveParser.
· Add Formula support, Hyperlink support, Named Range support.
· Improve Spreadsheet::ParseExcel::SaveParser compatibility with
