About this tool

Convert between CSV (comma-separated values) and JSON formats in both directions. Our converter handles CSV headers as JSON keys, supports custom delimiters (comma, semicolon, tab, pipe), properly handles quoted fields containing commas or newlines, and generates clean JSON arrays of objects. In JSON-to-CSV mode, it flattens JSON objects into tabular format with automatic header generation. Use it to convert spreadsheet exports for API consumption, transform API responses for spreadsheet analysis, migrate data between systems, or prepare data for database imports. The tool handles edge cases like empty fields, mixed types, and special characters in values.
