What is xlsx2md?

xlsx2md is a single-file JavaScript web app that reads .xlsx Excel files locally in the browser and extracts narrative text, tables, and images as Markdown. It processes entire workbooks in one pass, preserving rich text, links, formulas (preferring cached values), and even chart configs or shape SVGs. A lightweight Node CLI handles batch jobs with options like `--out` for Markdown or `--zip` exports.

Why is it gaining traction?

It stands out by running fully client-side—no servers, no uploads—ideal for sensitive files, while outputting clean Markdown ready for GitHub or AI prompts. Features like table detection modes (`balanced` or `border`), rich text in `github` formatting, and ZIP archives with fixed timestamps beat clunky online converters. Developers dig the zero-install browser flow plus CLI flexibility.

Who should use this?

Data engineers feeding Excel reports into LLMs, analysts converting multi-sheet workbooks to docs, or frontend devs building local file processors. It's spot-on for teams avoiding cloud tools with proprietary spreadsheets, or anyone scripting batch Markdown exports from .xlsx files.

Verdict

Grab it if you need quick, private Excel-to-Markdown conversion—browser app and CLI deliver reliably. At 11 stars and 1.0% credibility, it's immature with room for edge-case polish, but thorough docs and tests signal potential.
