UlvixorCSV to JSON Converter
Paste your CSV and get a perfectly formatted JSON array instantly, using the first row as the field headers. Everything runs in your browser, so your data is never uploaded to a server.
How it works
- Paste or type your CSV into the input panel (or use the built-in example).
- The tool treats the first row as the header and converts each following row into a JSON object.
- The result appears as an indented JSON array, ready to use.
- If the CSV has a formatting error, a message shows exactly which row it's on.
- Copy the resulting JSON or download it as a .json file.
Use cases
- Turn an Excel or Google Sheets export into JSON for an API or script.
- Prepare mock data in JSON format from a spreadsheet.
- Migrate tabular data into a NoSQL database or a configuration file.
- Quickly inspect the contents of a CSV by viewing it as structured objects.
