Turn CSV data into structured JSON (and back).
Developer utilities should be fast, copy-friendly, and predictable. Paste input, get formatted or converted output, and move on — no CLI install required.
Use this free CSV to JSON Converter whenever you need a reliable result without creating an account or installing software. It loads in one click and works on desktop and mobile browsers.
Tentaco runs this tool in your browser whenever possible. Text and structured input you paste are handled in the page session unless the tool explicitly fetches remote data. Close the tab or clear the page after use on shared computers. Features that call external APIs (such as URL fetchers) only send the data required for that request.
Comma, semicolon, and tab delimiters are supported, with auto-detection from the first rows.
Enable header row mode to use column names as object keys, or emit arrays of values per row.
