Convert Excel to CSV
This tool converts an Excel spreadsheet (.xlsx or .xls) to a plain CSV file with LibreOffice, ready for importing into databases, scripts and other apps.
When to use it
- Import spreadsheet data into a database or app.
- Get a plain-text version of a sheet for scripting.
- Share tabular data in a universal format.
Private & secure
Your Excel workbook is exported to plain CSV with LibreOffice on our server. It is uploaded encrypted, processed in a one-time workspace, and both files are deleted the instant the CSV is returned — your data is never kept.
Frequently Asked Questions
What if my workbook has several sheets?
CSV holds a single sheet, so the first (active) sheet is exported. Convert each sheet separately if you need them all.
Are my files uploaded to a server?
Yes. Exporting the active sheet to clean CSV runs through LibreOffice server-side, so the workbook is uploaded briefly. It is processed in isolation and erased once the CSV comes back.
Is it free? Is there a watermark or size limit?
Yes — free, no account, and no limits. Excel files up to 100 MB each can be converted.
