Which sheet becomes the CSV?

The sheet that's open when you export. A CSV holds one sheet — switch sheets in the studio and export again for the others.

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 CSV 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.

Q: Why convert XLSX to CSV?

An .xlsx workbook is Excel's standard workbook format since 2007; a CSV file is comma-separated values — one line per row, the format every database, CRM and online store imports. Online stores, CRMs, email tools and databases import CSV — not .xlsx.

Convert XLSX to CSV — the right way

Online stores, CRMs, email tools and databases import CSV — not .xlsx. Drop your .xlsx workbook above; it opens in Mega Excel Studio with the export window set to CSV, so you can look it over, change anything and download. The open sheet is written as UTF-8 CSV with each value as Excel shows it, formula results rather than formulas, and text that a spreadsheet could run as a formula made safe. A CSV file is comma-separated values — one line per row, the format every database, CRM and online store imports, and opens in Excel, Google Sheets, databases, CRMs and every importer.
