JSON to CSV Converter

Convert JSON Data to CSV Format

The CSV-X JSON to CSV converter allows you to transform JSON (JavaScript Object Notation) data into CSV (Comma-Separated Values) format, which is widely supported by spreadsheet applications like Microsoft Excel, Google Sheets, and LibreOffice Calc. This conversion is useful when you need to analyze API response data in a spreadsheet, import JSON data into a database that accepts CSV imports, or share data with non-technical stakeholders who prefer working with spreadsheets.

To use the converter, simply paste your JSON data into the input area. The tool accepts both JSON arrays of objects and single JSON objects. When converting, the keys of the first object become the CSV column headers, and each object in the array becomes a row. The converter uses Papa Parse's unparse function to handle edge cases like values containing commas, quotes, and newlines, ensuring RFC 4180-compliant CSV output.

Supported JSON Formats

The converter handles flat JSON arrays of objects, which is the most common format returned by REST APIs. Nested objects are serialized as JSON strings within the CSV cells. For best results, provide an array of objects with consistent keys. The output can be downloaded as a .csv file that opens directly in any spreadsheet application, or you can copy the CSV text to use elsewhere.
