Do I need to sign up?

No. Converting and downloading need no account. Signing in is only for saving the result to the cloud and continuing on another device.

Is the result watermarked?

No. Nothing is watermarked and there is no limit on how many times you convert.

Is my file uploaded to your servers?

No. The whole conversion happens in your browser. Open DevTools (F12) and watch the Network tab to check. The one thing that uses the network is the text-recognition engine for scans, downloaded once and only if you agree.

How big a file can I convert?

There is no limit. We no longer measure your file up front — that number was ours, not any device’s real ceiling. We just start; if this device genuinely cannot fit it, the browser says so and we pass on the reason, a way forward, and an event ID.

Does it work on a phone?

Yes, with the same features as on a computer. Very large files will simply take longer.

Will you start charging later?

It is free and unlimited today. We avoid absolute promises nobody can back, and there is no hidden sign-up wall or usage cap either.

Can I paste it into GitHub?

Yes — the output is GitHub-flavoured table syntax.

What about line breaks inside cells?

They become , which renders as a line break on GitHub and similar renderers.

And Markdown to Excel?

Not offered yet — paste the table into the online spreadsheet and use Text to Columns on “|”.

Excel to Markdown — free, no watermark, no sign-up

Turn an Excel or CSV file into Markdown tables: one “## sheet name” heading and a GFM table per sheet, numeric columns right-aligned, and pipes, line breaks and angle brackets escaped so nothing breaks the table. Paste it into a README, docs site, GitHub issue or notes app.

What comes across, and what does not

How to use it
