How to Convert CSV to JSON

You can paste tabular CSV text directly into the input box or click the file upload area to select a .csv or .txt file from your machine. The parser automatically reads the headers from the first row and transforms each subsequent row into a structured JSON object.

Customizable Options

• Delimiter Selection: Supports standard commas, tabs (TSV), semicolons (common in European CSV exports), and pipe characters.
• Type Parsing: Automatically converts numerical values (e.g., 100) and boolean strings (true/false) into native JSON types rather than keeping them as plain strings.
• Formatted Output: Switch between pretty-printed (indented) JSON for easy reading and minified single-line JSON for production use.
