Frequently asked questions
What can I convert JSON to?
This tool formats and validates JSON and converts it to YAML or CSV, so you can move data between APIs, config files, and spreadsheets quickly.
Does it validate my JSON?
Yes — it flags syntax errors as you work so you catch problems before they reach your application code.
Is my data sent anywhere?
No. All parsing and conversion happens in your browser, so your data stays on your device.
