JSON to CSV Converter accepts a JSON array of objects and produces a flat CSV file. Choose delimiter (comma, semicolon, or tab), toggle header inclusion, and download the result or copy it to the clipboard. Error messages explain invalid or non-array JSON input.
The tool expects a top-level JSON array of objects, e.g. [{"name":"Alice","age":30},...]. Objects with different keys are handled by using the union of all keys across all objects as column headers.
Values containing the delimiter character, double quotes, or newlines are automatically wrapped in double quotes, and internal double quotes are escaped by doubling them — per the RFC 4180 CSV standard.
The tool expects a top-level array. Wrap a single object in square brackets, e.g. change {"name":"Alice"} to [{"name":"Alice"}], to convert it.
Nested objects and arrays are converted to their JSON string representation within the cell, since CSV is a flat format with no concept of nesting.

Yes, there's a toggle to include or omit the header row, useful if you're appending the output to an existing CSV file.
Yes, for objects with consistent keys the column order follows the key order of the first object. Objects with extra keys add new columns at the end.
