I faced this exact struggle when trying to get clean Word exports for clients who don't touch Markdown. Pandoc is powerful but the CLI and template management can be a massive overhead for simple tasks.

I ended up building MarkdownCo Pro to bridge that gap. It focuses on maintaining formatting precision without needing to mess with Haskell filters or complex LaTeX setups. It’s been a fun challenge to handle nested lists and table alignments properly in .docx—definitely one of the trickier parts of the conversion logic.

I've been working on a tool specifically to handle these messy PDF-to-Markdown conversions because I ran into the same issues with tables and multi-column layouts.

I’ve optimized https://markdownconverter.pro/pdf-to-markdown to handle complex PDFs, including those tricky tables that span multiple pages and 2-column formats that usually trip up tools like Docling. It also extracts embedded diagrams/images and links them properly in the output.

Full disclosure: I'm the developer behind it. I’d love to see if it handles your specific datasheets better than the models you've tried. Feel free to give it a spin!

Cool! But given that often electronics documentation is covered by NDAs, my preferred solution is local-first if at all possible.
