Convert Excel to CSV online, free, with the formatting preserved exactly. Excel (XLSX) is the standard spreadsheet format with formulas, formatting, multiple sheets and charts. CSV is a simple tabular format that every spreadsheet and database can import. This tool uses a full LibreOffice engine on our secure servers to reproduce fonts, layout, tables and images faithfully — the same technology behind professional office suites — so your CSV looks just like the original, not a rough approximation.

Why convert Excel to CSV?
CSV gives you a fully editable file you can open and change in your favourite editor. Turning a Excel into CSV unlocks the content so you can reuse, update or restyle it instead of being stuck with a fixed layout.
How accurate is the conversion?
Very accurate. Because we run the full LibreOffice rendering engine rather than a simple text extractor, complex formatting — multi-column layouts, tables, embedded images, headers and footers, fonts — is reproduced faithfully. This is the same open-source engine trusted by governments and enterprises worldwide.
Common Uses
