JSON ↔ CSV

Paste your JSON array into the converter. Each JSON object becomes a CSV row, and object keys become column headers. Nested objects are flattened with dot notation (e.g., user.name becomes a column).

The tool supports JSON arrays of objects: [{"name":"John","age":30}]. Each object should have the same structure. Nested objects and arrays are supported but will be flattened or stringified.

Yes, you can typically choose delimiter (comma, semicolon, tab), quote character, and whether to include headers. Some tools also support selecting specific fields or flattening nested structures differently.
