How It Works

This tool takes a JSON array of objects and converts it into CSV (Comma-Separated Values) format. It automatically extracts all unique keys from every object to form the CSV header row, ensuring no columns are missed even if some objects have different fields.

Values containing the delimiter character, double quotes, or newlines are automatically wrapped in double quotes and properly escaped following the RFC 4180 standard. You can choose between comma, semicolon, tab, or pipe as your delimiter to match your target application's requirements.

All conversion happens in your browser using JavaScript. No data is uploaded to any server, so your sensitive data stays completely private.
