What the YAML Formatter does
YAML Formatter: formats Status and YAML Output from YAML Input (or paste JSON to convert).
Supply YAML Input (or paste JSON to convert) and you get Status and YAML Output back. Edit a field and the answer updates in place.
Typical users are developers debugging a payload. Spotting a malformed field is far quicker when the structure is laid out clearly.
Because it is all local, the tool is as fast as your device and as private as your own notes.
The rest of this page documents each field, the method, and a worked example built from the values the YAML formatter loads by default.
What do the YAML Formatter fields mean?
The YAML Formatter uses 1 input. You can work from the defaults, or clear them and start fresh, both work.
| Field | What to enter | Default |
|---|---|---|
| YAML Input (or paste JSON to convert) | paste or type any amount of text | name: YoursTools tools: 801 active: true |
How does the YAML Formatter work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same formatted output.
Checks happen up front, so errors surface next to the form instead of hiding in the output.
Worked example
These are the values the YAML Formatter loads by default, and the result it produces from them. Here is the calculation as it stands the moment the page loads.
| YAML Input (or paste JSON to convert) | name: YoursTools tools: 801 active: true |
|---|
| Status | Normalized YAML indentation (tabs → 2 spaces) |
|---|---|
| YAML Output | name: YoursTools tools: 801 active: true |

How to use it
- Paste your content into YAML Input (or paste JSON to convert).
- The tool reacts immediately rather than waiting for you to finish the form.
- The results panel then shows Status and YAML Output.
- Copy Link is the quickest way to send the exact scenario to someone else.
What this tool does not do
- Output follows the common convention for this format; a specific toolchain may have its own house style.
- Processing happens in your browser, so very large inputs are bounded by available memory.
- Nothing is saved between visits, so keep your own record of anything you need again.
Frequently asked questions
One thing: YAML Input (or paste JSON to convert). Nothing starts empty, letting you treat it as a what-if tool rather than a data-entry form.
With the values loaded when the page opens, status comes out as Normalized YAML indentation (tabs → 2 spaces). Any edit re-runs the calculation, so there is no stale number on screen.
Not at all: the whole thing runs offline once the page has loaded, which tells you nothing is being sent.
Nothing at all. There is no registration, no paywall and no per-use quota.
