The tool parses CSV and converts to JSON.
Copy the resulting JSON array.
Use CSV to JSON when importing spreadsheet data into web applications, APIs, or databases that expect JSON format. It is perfect for converting exported reports from Excel or Google Sheets into structured data for programmatic use. Frontend and backend developers use it to prepare seed data, configuration files, or test fixtures from tabular sources.
Yes, the first row of your CSV is automatically used as JSON property names. Each subsequent row becomes a JSON object with keys matching those headers. If your CSV lacks headers, the tool assigns generic column names (col1, col2, etc.) to keep the output structured.
The tool supports comma, semicolon, tab, and pipe separators for maximum flexibility. It can auto-detect the delimiter in most cases, or you can manually specify one. This ensures compatibility with CSV exports from different applications and locales.
Yes, the parser properly handles quoted strings that contain commas, newlines, or other special characters inside them. It follows the RFC 4180 standard for CSV parsing, correctly handling escaped quotes and multi-line fields to produce accurate JSON output.
