Super cool. Working on a local AI tool specifically for document workflow automation (where context = screen/web/folders/files), and this could come in super useful. I do most of the PDF/DOCX/etc. parsing natively in Rust, but having a nice way to see the output without spinning up Word or Powerpoint is a huge leap.

Thanks for releasing publicly.

nice - did you write a custom parser for PDF/DOCX? we wrote one for XLSX after running into event loop issues with sheet JS

[dvt]

Using lopdf[1] for PDF parsing, rtf-parser[2] for RTF, calamine[3] for XLSX, and I'm sure you know that DOCX/PPTX/etc. is basically just a zip file of XML + text. The LLM cares about textual data (which just gets moderately cleaned up post-extraction), so I (thankfully) didn't have to deal with rendering. But showing a preview or end-result to a user would be a huge plus, so I can see myself using your library.

What about rendering? That's the hard part.

[andrewlu0]

we built a library @extend-ai/react-xlsx on top of it that renders the parsed contents onto a canvas

testing was mostly manual with a test corpus we generated. its not perfect but its pretty close for most files we've seen

[dvt]

For me, rendering was just a nice-to-have.

Sorry I meant to ask the author of Extend UI not you.

First of all thanks for the great library. It is so much more thay an UI kit!

We wrote (should say are writing) our own xlsx parser in Rust on IronCalc:
