How to Convert Documents to Markdown Format While Retaining Formulas?

[GudaoStudio]

Hello everyone,
I have a question while trying to localize documents and create a knowledge base (in Chinese). Currently, the publicly available documents support HTML and PDF formats, but I am looking for a format that is easier to edit and manipulate. Is there a way to reconstruct the documents to obtain the Engineering Reference, Input Output Reference, and other documents in markdown format? I have tried to convert all HTML files into markdown format, which was almost successful, but at the cost of losing nearly all the formulas.
I would appreciate any advice or tips from anyone so that I can complete this task.

best.
