CSV to JSON Converter

Use this CSV to JSON converter to turn spreadsheet exports, comma-separated rows, tab-separated data, or sample datasets into structured JSON arrays. It is useful for API mock data, prototypes, and documentation examples.

How to use CSV to JSON Converter

Paste CSV, semicolon-separated, or tab-separated rows.
Choose the delimiter and decide whether the first row should become object keys.
Copy or download the JSON array for prototypes, docs, or mock API data.

Example workflow

Paste spreadsheet rows with headers such as name, email, and role, then convert them into a JSON array of objects.

Privacy and limits

CSV conversion runs locally in your browser, which is useful for small spreadsheets, sample data, and internal examples.

Review converted data types before using the output in code. CSV values are often interpreted as strings.

Common uses
