How to convert Excel to CSV for free?

Upload your .xlsx or .xls file and download a CSV ready to import into any system: ERPs, CRMs, databases or analytics tools. It also works the other way: paste or upload a CSV and get a well-formed Excel file. Conversion respects cells with commas, quotes and line breaks.

Financial data without risk

Spreadsheets often contain accounting data, customers or payroll. This converter runs 100% locally: your file never travels to a server, so you can convert sensitive information with peace of mind.

FREQUENTLY ASKED QUESTIONS

Are formulas preserved?

CSV is plain text: calculated values are exported, not formulas. When converting CSV to Excel, values are imported as regular cells.

Which CSV separator is used?

Comma by default, with automatic semicolon detection when importing European CSVs.
