Frequently Asked Questions
What JSON formats are supported?
The tool supports JSON arrays of objects (e.g., [{"name":"Alice","age":30}]). Each object in the array becomes one row. All objects should share the same keys for best results.
Are nested objects supported?
Yes. Nested objects are flattened using dot notation. For example, {"address":{"city":"New York"}} becomes a column called address.city.
Is my data stored anywhere?
No. All conversion happens in your browser — your data is never sent to any server. The tool is completely client-side.
What if my JSON has special characters?
Values containing commas, quotes, or newlines are automatically wrapped in double quotes and escaped per the RFC 4180 CSV standard.
