How It Works
Header row: When enabled, first row becomes object keys. When disabled, generates array of arrays.
Dynamic typing: Automatically converts numbers, booleans, and null values. Strings remain strings.
Delimiter: Leave empty for auto-detection (comma, semicolon, tab). Specify if auto-detection fails.
Output format: Array of objects (with header) or array of arrays (without header).
All conversion happens locally in your browser. Your data is never sent to any server.
