About the JSON to CSV Converter

The JSON to CSV Converter transforms a JSON array of objects into a comma-separated values (CSV) file. Paste a JSON array and get a clean CSV output with automatically mapped column headers, ready to open in Excel, Google Sheets, or any data analysis tool.

Converting JSON to CSV is a common task when exporting API data for use in spreadsheets, generating reports from database records, or preparing data for import into tools that don't accept JSON directly. The converter maps each key of the first object to a CSV column header and writes the values row by row.

All conversion runs locally in your browser — no JSON data is uploaded or sent to any server. The output is downloadable as a .csv file. Nested JSON objects are flattened to their string representation in the corresponding cell.
