JSON to CSV Converter
Convert JSON arrays into CSV format. Runs entirely in your browser.
FAQ
What JSON format is expected?
The input must be a JSON array of objects, e.g. [{"a":1}, {"a":2}]. Each object becomes a row, and the keys become column headers.
How are nested objects handled?
Nested objects and arrays are serialized as JSON strings within the CSV cell. For deeply nested data, consider flattening first.
Is my data private?
Yes. The conversion is performed entirely in your browser — nothing is uploaded.
