input

The JSON or YAML text to convert (up to 2 MB).

Target format. Default: yaml for JSON input, json for YAML input.

More options (4)

Source format; auto tries JSON first, then YAML.

Spaces per level. JSON: 0 puts items on their own lines without indentation. YAML: values below 2 are treated as 2.

Sort object keys alphabetically (default: keep input order).

JSON: single line without spaces. YAML: single-line flow style. Overrides indent.

How it works

  1. Paste your JSON or YAML text into the input field and set the format options you need.
  2. Press Run; the tool parses, validates, and converts your text with line-accurate error messages if anything is malformed.
  3. Download the converted file — converted.json or converted.yaml — or copy the output directly from the page.

Limits

Input text may be up to 2 MB and structures up to one million nodes; output may reach 8 MB. Each visitor gets 20 free runs per day without logging in. Runs beyond that draw 1 credit per call from prepaid credits tied to an API key.

Privacy

Your input is processed for the request and discarded afterwards; it is not kept or used for any other purpose. Usage records store only the time, tool name, status, duration, credits used, and a salted hash of the IP address.

Questions

Do I need an account for the first 20 runs?

What happens once I exceed 20 runs in a day?

Each additional run costs 1 credit drawn from prepaid credits attached to your API key.

Is my input text stored after conversion?

No. The input is processed for the request and discarded immediately; it is not retained or used for anything else.

How do I call this tool from code?

Can I upload a file or fetch a URL on this page?

No. The page accepts pasted text only; file upload and URL fetching are available through the API, not through this form.
