Convert YAML to JSON, or JSON to YAML, without sending the text to another service.
YAML is parsed with a YAML 1.2 reader and printed as indented JSON. JSON is parsed and printed as YAML. Aliases are limited so a huge alias expansion cannot stall the page.
YAML to JSON reads one document. JSON to YAML requires legal JSON, then prints a YAML document. Comments in YAML are not kept, because JSON has nowhere to put them.
Custom tags and enormous alias graphs are out of scope. If the text uses anchors heavily, simplify it before converting. The result is data, not a promise that a particular application will accept the keys.
Choose the direction that matches what you pasted.
Paste one document.
If YAML fails, look for a tab in the indentation or a tab character used as a space.
The JSON is { "ok": true }.
Expecting the YAML indentation to survive a round trip through JSON unchanged.
No. The conversion keeps the data, not the comments.
No. Paste one document.
