    Before you start

    Read a bounded YAML subset into JSON without evaluating custom tags. Anchors, aliases, merge keys and multiple documents are rejected; duplicate keys are errors.

    How to use this tool

    1. Paste content into “YAML input” or choose a local file. A selected file takes priority until removed.
    2. Check your input, then select “Convert to JSON”.
    3. Review the JSON result, then use the available copy or download controls.

    Supported inputs and limits

    YAML text is limited to 1 MiB; review types and structure after JSON conversion.

    Worked example

    Example input

    id: 9007199254740993
    name: "中文"
    ok: true
    Example options
    {}

    Example output

    {
      "id": 9007199254740993,
      "name": "中文",
      "ok": true
    }

    When something does not work

    Correct the reported syntax or range and run again. Formatting is not execution: scripts, SQL, expressions and pasted markup do not run against your system or a remote service.

    Frequently asked questions

    Are my files uploaded?

    No. Files and tool input are processed in your browser. Moving around the site can keep a temporary workspace in the same tab. Refreshing or closing the tab clears it, so download results you want to keep.

    What should I check in this result?

    Read a bounded YAML subset into JSON without evaluating custom tags. Anchors, aliases, merge keys and multiple documents are rejected; duplicate keys are errors.
