How do I convert CSV to JSON?

Paste your CSV data into the tool or upload a CSV file. The tool automatically detects headers and converts the data to JSON format with proper structure and data types.

Does it handle CSV headers?

Yes, the tool automatically detects headers in the first row and uses them as JSON property names. You can also disable header detection if needed.

What output formats are supported?

You can output as a JSON array (default) where each row is an object, or as a JSON object with row keys (row_1, row_2, etc.).

Is my CSV data secure?

Yes, all conversion happens locally in your browser. Your CSV data is never uploaded to any server.
