Self-hosted. Your files never leave your network.

Frequently asked questions
- How are CSV columns mapped to JSON?
- Column headers become JSON object keys, and each row becomes a JSON object in the output array. All conversion runs locally on your self-hosted SnapOtter server.
- Can I convert JSON back to CSV?
- Yes, the tool works in both directions. JSON arrays of objects are flattened into CSV rows with keys as column headers. Processing happens entirely on your own infrastructure.
- Is my data safe during conversion?
- Absolutely. SnapOtter is self-hosted and processes all files locally on your server. Your data is never transmitted to any external service during conversion.
