Frequently asked questions

How do I open a CSV file?

Drag the file onto this page or click “Choose file”. Check the preview, pick the delimiter if needed and click “Load”.

Is my file uploaded?

No. Your file is read and processed only in your browser. No data is sent to a server.

How do I save my changes?

Click “Download CSV”. You get a new CSV file with all your changes, with the same delimiter as the original file.

Can I open CSV files from Excel?

Yes. The delimiter is detected automatically, also the semicolon that Excel often uses. The downloaded file opens correctly in Excel, special characters included.
