Excel to Markdown Converter
Turn Excel spreadsheets into Markdown tables — drop an .xlsx file and copy a clean, aligned table for your README, docs or AI prompt. Runs entirely in your browser.
🔒 Your files never leave your device — conversion runs locally in your browser.
How it works
Drop your spreadsheet
An .xlsx from Excel, or one exported from Google Sheets or Numbers. Parsed locally, never uploaded.
Each sheet becomes a table
Displayed values are converted to aligned Markdown tables, one per sheet, with the header row styled.
Copy or download
Copy the Markdown for a README, docs or a prompt — or download the .md file.
About the formats
Excel — Microsoft Excel spreadsheet (.xlsx)
XLSX is Microsoft Excel's spreadsheet format, also produced by Google Sheets, Numbers and LibreOffice exports. A workbook holds one or more sheets of rows and columns — exactly the shape of a Markdown table. Converting a sheet to Markdown gives you a plain-text table you can paste into a README, a pull request, documentation or an AI prompt.
Markdown — Markdown
Markdown is a plain-text format that marks structure with simple punctuation — # for headings, ** for bold, - for lists. It has become the native output format of the AI era: ChatGPT, Claude, Copilot and coding agents all write Markdown, GitHub renders it, and note apps like Obsidian store everything in it. A .md file is just text, which is why it opens in any editor but looks unformatted without a renderer like this one.
Frequently asked questions
Is this safe? Do my files get uploaded?
No upload happens — ever. Converting Excel to Markdown runs entirely inside your browser. Your documents never leave your device, nothing is stored on any server, and the tool keeps working if you go offline after the page loads. That's also why there are no file size limits, no queues and no sign-up.
What if my workbook has multiple sheets?
Every sheet is converted: each becomes its own Markdown table under a heading with the sheet's name, so a multi-tab workbook turns into one well-structured document. Empty sheets are skipped automatically.
Are formulas and number formatting preserved?
You get the displayed values — what you see in the cells is what lands in the table. Formulas are replaced by their current results (Markdown has no formula engine), and formatted numbers like currencies, percentages and dates are carried over as their formatted text.
Does this work with Google Sheets or Numbers files?
Via export, yes: download the sheet as .xlsx (File → Download in Google Sheets) and drop it here. For a quick copy-paste path without exporting, copy the cell range and paste it into the Markdown Table Generator instead — both routes produce the same clean table.

Can I convert multiple spreadsheets at once?
Yes — drop in as many files as you like. Because conversion happens on your own computer instead of a server, there is no per-file fee, no daily cap and no waiting in line. Files are processed one after another and you can download results individually or grab everything as a single ZIP.
Is there a file size or quantity limit?
There is no hard limit. Server-based converters cap uploads because your files consume their bandwidth and CPU; here the work happens on your machine, so the only practical limit is your device's memory. Even book-length documents convert in seconds — text is light work for a modern browser.
