Is this Excel to CSV converter free?

Yes — Morphix is 100% free, with no signup, no watermark and no per-file caps from us.

Are my spreadsheets uploaded anywhere?

No. Parsing runs in your browser with SheetJS, so the workbook never leaves your device.

Can it export every sheet of a workbook?

Yes. Every worksheet is converted and listed separately, so you can download each one as its own CSV file.

Why does Excel show all data in one column?

That happens when your regional Excel expects semicolons. Switch the delimiter to semicolon before downloading and the columns will split correctly.

Excel to CSV — Convert XLSX to CSV in Browser

Convert Excel to CSV without uploading

Spreadsheets usually hold the most sensitive data you own — payroll, customers, invoices. Morphix parses your workbook locally with SheetJS, so nothing is transmitted anywhere. You get the same clean CSV Excel's own "Save As" produces, without the account, the queue or the watermark.

Every sheet, separately

Excel can only export the active sheet at a time. Morphix converts the whole workbook at once and lists each worksheet with its row count and a preview, so you can download exactly the tabs you need.

Comma, semicolon or tab

Comma — the standard for databases, scripts and US/UK Excel.
Semicolon — use this if European Excel dumps every row into one column.
Tab — safest when your cells themselves contain commas.
Output is UTF-8 with a BOM, so accents and non-Latin characters survive the trip into Excel.
