Frequently asked questions

Is my CSV file uploaded to any server?

No. The CSV editor works entirely in your browser using local client-side processing. Your files never leave your device, ensuring complete privacy.

Can I add or remove rows and columns?

Yes. You can add rows and columns with a single click, and remove specific columns or rows using the hover trash icon controls.

What delimiter does the editor support?

The tool automatically detects common delimiters (like comma, semicolon, tab or pipe) when you upload a file, and saves your changes using the standard comma-separated format.

Can I copy the CSV data to clipboard?

Yes, you can copy the serialized CSV directly to your clipboard or download it as a .csv file.
