π JSON β CSV Converter
Convert between JSON arrays and CSV format, bidirectional, instant, client-side.
The JSON to CSV Converter handles one of the most common data format conversion tasks in IT and data work. JSON arrays are the standard output format for APIs and most modern applications, while CSV is the standard for spreadsheets, database imports and data pipelines. Being able to convert between them quickly without writing a script or opening a development environment saves significant time.
The tool works in both directions, JSON arrays to CSV and CSV back to JSON. It supports custom delimiters (comma, semicolon, tab, pipe) to handle regional formats and different application requirements. The quote style option controls how string values are quoted in the CSV output, which matters when importing into applications that have strict parsing rules.
The CSV to JSON direction automatically detects numeric values and converts them to proper JSON numbers rather than strings, which is important for downstream applications that need to perform arithmetic or comparisons on the data. All processing happens in your browser with no data sent to any server.
