    What this tool does

    JSON Formatter makes JSON easier to read (pretty print) or smaller (minify) without sending your data to a server. If the input is invalid, you’ll see a clear error message.

    Why NO UPLOAD matters

    JSON often contains private data (tokens, emails, internal IDs). This tool runs entirely in your browser, so nothing is uploaded. All processing happens locally in your browser. Files are never uploaded.
