How It Works
This tool converts CSV (Comma-Separated Values) data into a JSON array of objects. The first row of your CSV is used as the header row, providing the key names for each JSON object. Each subsequent row becomes an object in the resulting array.
The parser automatically detects whether your CSV uses commas, semicolons, tabs, or pipes as delimiters by analyzing the first line. It also properly handles quoted fields containing delimiter characters, newlines, and escaped double quotes following the RFC 4180 standard.
Numeric values are automatically converted to numbers in the JSON output. All processing happens entirely in your browser with no server communication.
