    What this tool does

    JSON to CSV turns a JSON array of objects into a standard CSV table. It’s designed for quick exports: you can paste JSON from an API response or a config file and instantly get a CSV you can open in spreadsheets.

    Why NO UPLOAD matters

    Your JSON can contain private data (names, emails, internal IDs). This tool runs 100% client-side and never sends anything to a server. All processing happens locally in your browser. Files are never uploaded.

    Privacy & Security
    All processing happens locally in your browser. Files are never uploaded.
