Good to know. Merged cells keep the value in the first cell only, and formatting like fonts and colors isn't carried over. The preview shows only the first rows.

FAQ

FAQ

What if a cell contains a | or a line break?

In Markdown, | is escaped as \| and line breaks become <br>, so the table stays intact.

Does it handle workbooks with several sheets?

Yes. After opening the file you can pick a sheet, and its contents go into the input box where you can still edit them.

Is my pasted data sent anywhere?

No. The conversion happens only in your browser.
