FAQ
How are nested objects handled?
Nested objects are flattened using dot notation. For example, {"user": {"name": "Alice"}} becomes a column named 'user.name' with value 'Alice'. Arrays of primitives are joined with semicolons.
What if my JSON has inconsistent keys?
The converter collects all unique keys across all objects and uses them as columns. Objects missing a key will have an empty cell for that column. This is standard CSV behavior.
Can I convert CSV back to JSON?
Yes. Use a CSV-to-JSON converter (or the reverse of this tool). The conversion is lossless for flat data but may not perfectly reconstruct nested structures that were flattened during JSON-to-CSV conversion.
