About JSON to CSV Converter

JSON to CSV Converter is a free web tool that turns JSON data into CSV files. You can paste JSON, upload a file, or fetch it from a public JSON endpoint URL. Sample datasets are included for trying it out.

Conversion runs entirely in the browser, so data is not uploaded to a server or stored. Before exporting, you can inspect the result in an interactive table with column sorting and search filtering, or view the raw CSV. The output can be copied to the clipboard or downloaded as a .csv file.

Options include choosing the delimiter (comma, semicolon, tab or pipe), including or omitting a header row, flattening nested objects into columns, and converting automatically as you type. The input editor offers syntax highlighting. It is aimed at developers, data analysts and spreadsheet users who need a quick, private conversion.
