FAQ

How do I convert JSON to CSV?

Paste a JSON array (e.g. [{"name":"Alice","age":30},{"name":"Bob","age":25}]) into the input. The converter extracts keys as column headers and values as rows.

What if my JSON has nested objects?

Nested objects are flattened using dot notation — {"address":{"city":"NY"}} becomes an address.city column.

What separators are supported?

Comma (standard CSV), semicolon (common in European locales), tab (TSV), and pipe.
