Frequently asked questions

What is a CSV file?

CSV is a simple table format: one row per line, columns separated by commas. Every spreadsheet and database can import it. CSV imports into Excel, Google Sheets, databases and almost every analytics tool.

What can I convert CSV files to?

TSV, JSON, YAML, TOML, XML, NDJSON, Excel, ODS. Pick a target after adding your files.

Are my files uploaded to a server?

No. The conversion runs entirely in your browser using WebAssembly. Your files never leave your device, so it is safe for private photos, contracts and business data. Once the page has loaded it even works offline.

Is it free? Are there limits?

It is free, with no sign-up, no watermark and no daily limits. Because nothing is uploaded there is no upload size limit either; the only limit is your device’s memory, which matters mostly for very large videos.
