Does the first row need to be headers?

Yes. The tool treats the first row as the column names. These become the keys in the resulting JSON objects. Ensure your CSV has a header row.

What about fields containing commas?

The parser correctly handles RFC 4180 quoting. Fields wrapped in double quotes may contain commas, and escaped quotes (double double-quotes) are unescaped in the output.

Can I convert a CSV exported from Excel?

Yes. Excel-exported CSVs use standard comma-separated format with quoted fields. Paste the CSV content directly into the input field and the tool will parse it correctly.

CSV to JSON reads the first row of your CSV as column headers and maps every subsequent row into a JSON object. Handles quoted fields that contain commas or newlines, and trims surrounding whitespace from values. The output is a formatted JSON array ready to use in your application or API.
