After converting, verify that nested objects, arrays, and field names carried over correctly — especially for JSON↔CSV conversions which handle nested data differently.
💾
Always keep a copy of your original data file. Browser-based tools process data in memory and cannot undo changes to your source files.
📋
Special characters (accents, emojis, non-Latin scripts) can break during format conversion. Verify the output in your target application and look for garbled characters.
Yes — free, no sign-up, no size limit. Convert as much JSON data as you need. We also offer CSV to JSON Converter for the reverse conversion.
All conversion runs locally in your browser — your JSON is never sent to any server. API tokens, customer records, and proprietary data stay on your device.
Nested objects are dot-notation flattened into column headers (e.g., "address.city"). Use JSON Formatter to inspect your JSON structure before converting.
Arrays within objects are serialized as JSON strings in the CSV cell. Normalize your data structure with the JSON Formatter before converting if you need a fully flat output.
