So I just tried this with a bunch of medium-complex documents and it's wildly wrong. I suspect the authors have never seen an actually complicated Word document?
Do you have any actual examples of documents where it did not work?
My examples are all internal/confidential, but if someone from the project wants an example I could probably do some search/replace redaction. It would be a lot of work though because there's photographs and such too, and indexes, and tables, and documents inserted by reference, cross references, conditional fields, bibliography fields, formula fields, etc etc.
vibe coded, it seems from the commit history (and readme lol)
