Microsoft PowerPoint OpenXML File Surgeon
This is a small utility for performing some font-related surgical operations on Microsoft PowerPoint OpenXML files (PPTX). Microsoft PowerPoint, as of at least January 2020, can produce PPTX files which are "broken" when it comes to fonts:
Broken Font Embedding: Sometimes it contains some font embedding information, but the actual font data is partially missing and PowerPoint is not willing to correct this through any means of its user interface (including disabling and re-enabling the font embedding option or exporting and re-importing via XML format). For this,
pptx-surgeonprovides the possibility to completely remove all font embedding information which resets the PPTX file back to a consistent state (where PowerPoint again is willing to correctly embed the fonts from scratch).
Hidden Font References: Often it contains references to previously used fonts, although no user interface reachable shape any longer uses these fonts. For this,
pptx-surgeonprovides the possibility to map font names in both the theme, slide master and slides. This gets rid of the previous references to old fonts.
