How It Works

1

Parses the CSV header row locally to determine object key names.

2

Splits each subsequent row into matching key-value pairs, handling commas inside quoted fields.

3

Outputs indented, copy-ready JSON, built in your browser without sending your data to an Alona Tool server.

Frequently Asked Questions

Yes, the parser correctly handles quoted CSV values so commas inside a field are not treated as column separators.
