Free JSON to CSV Converter Online

Yes. The downloaded CSV file opens directly in Microsoft Excel, Google Sheets, LibreOffice Calc, Apple Numbers, and any other spreadsheet application. Values containing commas, quotes, or line breaks are escaped correctly so columns line up properly. If Excel ever splits columns oddly, check that your regional list separator matches the comma used in the file.

Yes. Nested objects are flattened into columns using dot notation. For example, {"address": {"city": "Delhi"}} becomes a column named address.city. This keeps everything in a single flat table that spreadsheets can read. Very deeply nested structures or arrays inside arrays may need simplifying first, since a flat CSV grid cannot represent arbitrary hierarchy.

The input should be an array of objects, such as [{"name": "John", "age": 30}, {"name": "Asha", "age": 25}]. Each object becomes one row in the CSV and each key becomes a column. A single object also works as one row. The objects do not all need identical keys — the converter collects every key it finds and fills missing values with blanks.

The converter scans all objects, collects the complete set of keys, and creates a column for each one. Where a particular object does not have a value for a column, that cell is left empty. This means you get a consistent table even with irregular data, which is common in real API responses where some records include optional fields and others do not.

Values that contain commas, double quotes, or line breaks are automatically wrapped in quotes and escaped according to the CSV standard. This prevents a value like "Pune, Maharashtra" from being split into two columns. The escaping ensures the file opens cleanly in any spreadsheet program without misaligned data, which is a frequent problem when CSVs are built by hand.

Yes, as long as the response is a JSON array of objects. Copy the response from your browser's network tab, an API client like Postman, or a curl command, paste it in, and convert. This is a quick way to share API data with non-technical teammates or load it into a spreadsheet for filtering, sorting, and charting without writing any export code.

Yes. All conversion happens locally in your browser using JavaScript, so the JSON you paste and the CSV you download never touch a server. This makes the tool safe for internal records, customer data, or any sensitive export. As always, handle the downloaded file responsibly, but the conversion step itself keeps your data entirely on your own device.

This usually happens when objects contain nested structures that get flattened with dot notation, producing headers like user.address.city, or when some objects include extra optional fields. Review your JSON to confirm the shape you expect. Simplifying nesting before converting, or selecting only the fields you need, gives a cleaner header row that is easier to work with in a spreadsheet.
