Turn a CSV table into structured JSON for an API, a script or a config file — without pasting your data into some random website's server. BunnyConvert parses the CSV in your browser, so business data and customer lists never leave your device.

How it works
- Open the CSV to JSON tool and add your .csv file.
- Convert — rows become JSON records using the header row as keys.
- Download the JSON file, ready for your API or code.
Frequently asked questions
- How are the JSON keys determined?
- The first row of your CSV is used as the header, and each following row becomes a JSON object with those keys.
- Is this safe for sensitive data?
- Yes — parsing happens in your browser, so exports with customer or financial data are never uploaded to any server.
- Is CSV to JSON free?
- Yes, it's completely free on the web with no limits. Files over 20MB are a Pro feature.
