Describe the Update

SCTK already supports extracting Excel documents. Especially for free software, Libre Office documents are rather common as well, but cannot be extracted at the moment, while the general structure seems to be similar to at least some extent (archive holding XML files).

How This Feature will help you/your organization

Make sure to catch licenses from Libre Office documents, which are used for documentation for example.

Possible Solution/Implementation Details

Add functionality to extract the corresponding containers.

Example/Links if Any

Gnome File Roller supports extracting the individual files of a .ods (spreadsheet) file for example.

Thanks. We already some minimal way to extract this in extractcode with an option for office document. This may not be the extract you expect, instead it treats modern office documents as the zip they really are, and process them as an archive. Could this be what you are looking for?

[stefan6419846]

As mentioned, this seems to work for Microsoft Office documents only, but not for Libre Office specific formats - at least with the dependencies bundled by the latest SCTK release. Handling them as ZIP files is totally fine for me.

The actual maintainers might know better about this, but I assume that this should probably go into https://github.com/aboutcode-org/extractcode
