About Json Csv Converter
Json Csv Converter is used to convert JSON arrays to CSV for use in spreadsheets, and CSV back to JSON for use in APIs and applications. It flattens the JSON array's object keys into CSV column headers and maps each object's values into rows, or reverses the process. Deeply nested JSON objects do not map cleanly to flat CSV — flatten your JSON or use the nested key separator option before converting. Json Csv Converter runs free in your browser at abovetool.com — no signup required.
