Are merged cells kept?

Yes — they become cells with colspan and rowspan, so the table looks like the sheet.

Why convert XLSX to HTML?

An .xlsx workbook is Excel's standard workbook format since 2007; a web page is the language every web page is written in. Showing a workbook on a web page or in an email without a screenshot nobody can copy from.

How much does it cost?

You can open your file, convert it and check or change everything in the studio before you pay anything. Downloading the finished file is part of every MojoPDF plan — start with the 7-day trial for $1 and cancel any time.

Is it safe to convert XLSX files to HTML here?

Yes. Your file travels over an encrypted connection and stays private to you — nobody else can open it. Projects you save are kept in your account until you delete them, and download links we email you expire after 7 days.
