JSON to CSV Converter

JSON to CSV Converter is a free web tool that turns JSON data into CSV files. You can paste raw JSON, upload a .json file, or fetch a public JSON endpoint by URL. The conversion runs in your browser, so the data is parsed and converted locally without being uploaded to a server.

The tool lets you choose a delimiter for the output, including comma, semicolon, tab, or pipe, and turn nested object flattening on or off. Nested keys are mapped to dot-separated column headers such as user.address.city, and values containing commas, quotes, or line breaks are quoted according to RFC 4180. Before exporting, you can review the result in an interactive table view with sorting, search, and pagination, then copy the CSV or download it as a .csv file.

The page is aimed at developers, data analysts, and spreadsheet users who need to move API responses or database exports into Excel, Google Sheets, Pandas, or SQL tools.
