Excel::Template(3) User Contributed Perl Documentation Excel::Template(3)
 

Excel::Template - Excel::Template

First, make a template. This is an XML file, describing the layout of the spreadsheet.
For example, test.xml:
  <workbook>
      <worksheet name="tester">
          <cell text="$HOME" />
          <cell text="$PATH" />
      </worksheet>
  </workbook>
Now, create a small program to use it:
  #!/usr/bin/perl -w
  use strict;
  use Excel::Template;
  # Create the Excel template
  my $template = Excel::Template->new(
      filename => 'test.xml',
  );
  # Add a few parameters
  $template->param(
      HOME => $ENV{HOME},
      PATH => $ENV{PATH},
  );
  $template->write_file('test.xls');
If everything worked, then you should have a spreadsheet called text.xls in your working directory that looks something like:
             A                B                C
    +----------------+----------------+----------------
  1 | /home/me       | /bin:/usr/bin  |
    +----------------+----------------+----------------
  2 |                |                |
    +----------------+----------------+----------------
  3 |                |                |

This is a module used for templating Excel files. Its genesis came from the need to use the same datastructure as HTML::Template, but provide Excel files instead. The existing modules don't do the trick, as they require replication of logic that's already been done within HTML::Template.

I do a lot of Perl/CGI for reporting purposes. In nearly every place I've been, I've been asked for HTML, PDF, and Excel. HTML::Template provides the first, and PDF::Template does the second pretty well. But, generating Excel was the sticking point. I already had the data structure for the other templating modules, but I just didn't have an easy mechanism to get that data structure into an XLS file.

This creates a Excel::Template object.
Parameters
FILE / FILENAME
Excel::Template will parse the template in the given file or filehandle automatically. (You can also use the parse() method, described below.)
If you want to use the __DATA__ section, you can do so by passing
  FILE => \*DATA
    
RENDERER
The default rendering engine is Spreadsheet::WriteExcel. You may, if you choose, change that to another choice. The legal values are:
Excel::Template->RENDER_NML
This is the default of Spreadsheet::WriteExcel.
Excel::Template->RENDER_BIG
This attempts to load Spreadsheet::WriteExcel::Big.
Excel::Template->RENDER_XML
This attempts to load Spreadsheet::WriteExcelXML.
USE_UNICODE
This will use Unicode::String to represent strings instead of Perl's internal string handling. You must already have Unicode::String installed on your system.
The USE_UNICODE parameter will be ignored if you are using Perl 5.8 or higher as Perl's internal string handling is unicode-aware.
NOTE: Certain older versions of OLE::Storage_Lite and mod_perl clash for some reason. Upgrading to the latest version of OLE::Storage_Lite should fix the problem.
Deprecated
BIG_FILE
Instead, use RENDERER => Excel::Template->RENDER_BIG

This method is exactly like HTML::Template's param() method.

This method actually parses the template file. It can either be called separately or through the new() call. It will die() if it runs into a situation it cannot handle.
If a filename is passed in (vs. a filehandle), the directory name will be passed in to XML::Parser as the Base parameter. This will allow for XML directives to work as expected.

Create the Excel file and write it to the specified filename, if possible. (This is when the actual merging of the template and the parameters occurs.)

It will act just like HTML::Template's output() method, returning the resultant file as a stream, usually for output to the web. (This is when the actual merging of the template and the parameters occurs.)

This allows you to register a class as handling a node. q.v. Excel::Template::Factory for more info.

This is a partial list of nodes. See the other classes in this distro for more details on specific parameters and the like.
Every node can set the ROW and COL parameters. These are the actual ROW/COL values that the next CELL-type tag will write into.
WORKBOOK
This is the node representing the workbook. It is the parent for all other nodes.
WORKSHEET
This is the node representing a given worksheet.
IF
This node represents a conditional expression. Its children may or may not be rendered. It behaves just like HTML::Template's TMPL_IF.
LOOP
This node represents a loop. It behaves just like HTML::Template's TMPL_LOOP.
ROW
This node represents a row of data. This is the 1 in A1. There is no COLUMN node, as of yet.
FORMAT
This node varies the format for its children. All formatting options supported in Spreadsheet::WriteExcel are supported here. There are also a number of formatting shortcuts, such as BOLD and ITALIC.
BACKREF
This refers back to a cell previously named.
CELL
This is the actual cell in a spreadsheet.
FORMULA
This is a formula in a spreadsheet.
RANGE
This is a BACKREF for a number of identically-named cells.
VAR
This is a variable. It is generally used when the 'text' attribute isn't sufficient.

None, that I know of.

This is production quality software, used in several production web applications.

I use Devel::Cover to test the coverage of my tests. Every release, I intend to improve these numbers.
Excel::Template is also part of the CPAN Kwalitee initiative, being one of the top 100 non-core modules downloaded from CPAN. If you wish to help out, please feel free to contribute tests, patches, and/or suggestions.
