Questions and answers
How do I convert JSON to CSV?
Drop your JSON files on this page, or choose them, then press Convert. Your browser does the work and you download the CSV file, or a ZIP when there are several.
Will anything be lost?
No data is dropped. Nested data is flattened into column names like address.city, and every value becomes text, as CSV has no number type.
Can I convert several files at once?
Yes. Several files download together as a ZIP, and the whole batch counts as one conversion.
How is nested JSON handled?
Nested objects become dotted columns like address.city, and arrays become numbered columns like tags.0. A top level array gives one row per item.
