About CSV to JSON

The CSV to JSON Converter transforms comma-separated data into a JSON array of objects, using the first row as the property names for every object. It's the quickest way to move spreadsheet exports and database dumps into a format your code or API can consume. Parsing runs locally in your browser, so your data never touches a server. It handles quoted fields and configurable delimiters. To convert the other way, use the JSON to CSV converter.

How to Use

1Open CSV to JSON and paste or type your data into the input area.
2Adjust any available options to match the result you want.
3Your output is generated instantly — no button-clicking required for most tools.
4Use the Copy or Download button to save your result.

Common Use Cases

Debugging API responses while building web and mobile apps
Cleaning up minified or messy JSON from logs and network tabs
Preparing configuration files and fixtures for testing
Converting data between JSON and other formats for imports/exports

Frequently Asked Questions

Does the first row become the JSON keys?

Yes. The header row is used as the property names, so each subsequent row is converted into an object with those keys mapped to its cell values.

Does it handle commas inside quoted fields?

Yes. Fields wrapped in double quotes can contain commas, line breaks, and escaped quotes, and they are parsed as a single value rather than split.

Is CSV to JSON free to use?

Yes. CSV to JSON is completely free with no sign-up, no subscription, and no usage limits. Every tool on CodeUtilityKit is free forever.

Is my data safe when I use CSV to JSON?

Absolutely. CSV to JSON runs entirely in your browser. Your input is processed locally with JavaScript and is never sent to, stored on, or logged by any server — so it is safe even for private or sensitive data.
