## **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.
