Does the llamaindex PDF indexer correctly deal with multi-column PDFs? Most I've seen don't, and you get very odd results because of this.

- pierre 2y agoLocally you can choose pypdf or mupdf wich are good but not perfect. If you can send your data online llamaparse is quite good.

- rspoerri 2y agoi've made quite good conversions from pdf to markdown with https://github.com/VikParuchuri/marker https://github.com/VikParuchuri/marker . it's slow but worth a shot. Markdown should be easily parseable by a rag. i'm trying to get a similar system setup on my computer.
- nl 2y agoThis looks worth exploring, so thanks. The author has done a bunch of work beyond what PyMuPDF does on multicolumn layouts.
