FAQ

  • What does comparing two presentations actually report?
    Whether shapes, text and layout match between the two files, so you can find what changed between two revisions of a deck without opening both.
  • Which formats can be compared?
    PPT, PPS, PPTX, POTX, PPSX, PPTM and ODP.
  • Is this a diff tool that produces a marked-up presentation?
    No. It answers whether and where the presentations differ; it does not generate a third deck with tracked changes. Building that on top of the result is your code’s job.
  • Can I compare a legacy .ppt against a modern .pptx?
    Yes. Both are read into the same model before comparison, so a format change between revisions does not by itself register as a difference in content.
