Use a text template to generate an Excel *.xlsx file


This module provides the capability of using a text template to generate an Excel file. It is a WIP and has no working code at the moment. If you are interested in the concept, please star the project, follow it, and file a feature request issue.

The project will use several Perl modules which will have to be installed for the distro to work (I use cpanm for that):


This project started when I was trying to automate creating forms for my tax return. I have a need to generate multiple workbooks, one worksheet per workbook, from a template, and am designing my own format for that purpose. I will use the Raku language to parse the text-file template, then, with the aid of the Raku module Inline::Perl5, I will read my xlsx data files with one of the Perl xlsx readers and then use this module to write new, filtered files in the form of the template.

I am just starting, but I'm looking at a template format something like this, one line per row, cells separated by pipes (|), key/value attribute pairs (using a syntax similar to Raku) following the cell content:

# This is a comment. The following row describes one xlsx row with four columns (the # first column being empty) and it has an ending comment. # Comments are stripped to the end-of-line eol before parsing the row. | some text | 5.26 | ="some formula" :color(red) :width(2) # comment... # empty rows are ignored, the worksheet will have all rows padded with empty cells # to the maximum number of cells found on any row # another comment and more rows following | # this is a row with two empty cells

I plan to use Raku's grammar to parse the template file.
