How to Convert JSON to CSV Online
Paste your JSON array into the input panel and click Convert to CSV. The tool automatically detects all keys from the JSON objects and creates CSV columns, including nested objects through automatic flattening. Toggle Include Header to control whether the first row contains column names.
The JSON input must be an array of objects (or a single object). Each object becomes one row in the CSV output. Nested objects are flattened using dot notation — for example, "address.city" becomes a column header.
