Paste your JSON data or upload a .json file, and FileNaut automatically converts it to CSV format. Preview the result and download as .csv file.
Can it handle nested JSON objects?▼
Yes. Nested objects are flattened using dot notation (e.g., user.address.city) so all data fits into a flat CSV structure.
What JSON structures are supported?▼
FileNaut handles arrays of objects (most common), nested objects, arrays within arrays, and mixed data types. Invalid JSON is flagged with error messages.
