Paste a JSON array of objects into the left panel and get a clean CSV in the right panel instantly. Each object becomes a row, and keys become column headers. Download the result as a .csv file ready for Excel or Google Sheets.
CSV is a flat, tabular format. The converter works best with a JSON array of objects where every object has the same keys — each object becomes one row, and the keys become column headers. Nested objects or arrays within a row will be serialized as strings. If your JSON is a single object rather than an array, wrap it in square brackets first.
The input must be a JSON array of objects, e.g. [{"name": "Alice", "age": 30}, {"name": "Bob", "age": 25}]. Each object becomes one CSV row and the keys become column headers.
The converter handles mixed keys gracefully — all unique keys across all objects are used as column headers, and missing values are left empty in the corresponding cells.
Nested objects and arrays are serialized as strings in the CSV cell. For complex nested structures, you may want to flatten your JSON first before converting.
Yes. The output uses standard comma-separated values with a header row, which opens directly in Excel, Google Sheets, LibreOffice Calc, and any other spreadsheet application.
No. Conversion happens entirely in your browser using the PapaParse library. Your data never leaves your machine.
