CSV to JSON Converter

CSV to JSON conversion transforms Comma-Separated Values (CSV) data into JavaScript Object Notation (JSON) format. Each row in the CSV becomes a JSON object, and each column becomes a property of that object.

This tool features:

• Auto-detect delimiter — Automatically detects commas, semicolons, tabs, or pipes.
• Header row support — Uses the first row as object keys, or generates generic column_1, column_2, etc.
• Number detection — Automatically converts numeric strings to numbers.
• RFC 4180 compliant — Handles quoted fields, escaped quotes, and multiline values.

1. Paste your CSV — Copy and paste any CSV data into the input textarea. You can also click Load Example to load sample data.
2. Choose settings — Select the delimiter (or leave as Auto-detect) and toggle whether the first row should be used as header names.
3. Convert — Click Convert to JSON to generate the JSON output. The tool handles proper escaping and number detection automatically.
4. Copy or download — Use the copy button on the output area or click Download .json to save the result as a file.
