Frequently Asked Questions
How do I convert Excel (.xlsx) to Markdown table?
Paste your Excel (.xlsx) into the box above and the Markdown table appears instantly below — there is no button to press and nothing to upload. The whole conversion runs in your browser, so you can copy the result or download it as a file. If the input has a problem, a clear message explains exactly what to fix.
Is this converter free and private?
Yes on both counts. It is completely free with no signup or limits, and it is private because everything happens locally in your browser — your data is never sent to a server. That makes it safe for confidential exports and customer data, and it keeps working offline once the page has loaded.
Is my spreadsheet uploaded anywhere?
No. The file is read directly in your browser using JavaScript and never leaves your device — nothing is sent to a server at any point. That is what makes it safe for financial models, HR data and other confidential spreadsheets, and it is why the tool still works with your network disconnected.
Is there a size limit?
There is no fixed limit because nothing is uploaded — the only real constraint is your device's memory, so even large files convert quickly on a normal computer. Very large inputs are handled more comfortably on a desktop browser than on a phone.
Does it work on mobile and every browser?
Yes. It runs in any modern browser on Windows, Mac, Linux, iPhone and Android with nothing to install, and works offline once loaded. The result can be copied or downloaded on any device.
