Research existing solutions for extracting text from proprietary Microsoft file formats.


For moin2, we already have quite some converters (including Open Document Format [OpenOffice / LibreOffice]), but nothing for Microsoft Office formats. Now we need to create a survey of the GPL2+ license compatible code that can extract text from these proprietary file formats.

We need to know:

  • is a license compatible to GPL2+ used?
    • for python libraries e.g.: GPL, BSD, MIT, ... (not: Apache License 2)
    • in general: a free software license, not any proprietary license
  • the programming language used
    • strongly preferred is library code in python (we can just call it)
    • also maybe working is a commandline tool (supported platforms?) that we can call as a subprocess
  • windows-only solutions are not wanted
  • compatibility with different file formats (mainly Word but also Excel and Powerpoint)
  • compatibility with different versions (i.e. .DOC and .DOCX)
  • reliability (is it well-maintained code, is it recently updated?)

Deliverable: wiki page


Many Moin users would like to have a platform-independant, pure python way to extract text for indexing.

Researching existing code base is a first step on this direction.

Skill Requirements

You'll need to do a lot of search on the Web. Discuss with moin devs online on IRC.
