DEVELOPER BENCH
Serialize a JSON value as plain YAML with consistent indentation using a pure-TypeScript writer. The converter handles plain objects, arrays, strings, numbers, booleans, and null.

No preset yet. A preset stores the values in this form — never the result — and only for workbenches that run entirely in your browser.
Collections
Saved on this device only. Turn on sync to carry them to another device.
BATCH / ONE VALUE PER LINE
Up to 200 lines, one at a time, in this browser. Each line takes the place of json and everything else stays as you set it. Nothing is uploaded, and the row limit is not exceeded silently.
METHOD / LOCAL RUN
The JSON value is parsed and emitted with a deterministic pure-TypeScript serializer that quotes scalar keys only when required.
Boundary: Supports plain objects, arrays, strings, numbers, booleans, null. Does not handle exotic types, anchors, or YAML 1.2 specific features.
The calculation or transformation runs in your browser using the values entered above. No input is sent to UtilityForge for this tool.

No. This published tool runs locally in your browser. UtilityForge does not send the values entered in this workbench to a server.
No. This workbench runs in the page: JSON input are read by the code your browser already downloaded, and UtilityForge receives neither the values nor the result.
Yes, and it is enforced rather than advertised: JSON input (100,000 characters). The limit is a browser input limit on a tool that runs on this device, so nothing is truncated after being sent anywhere.
