FAQ
Which JSON values are supported?
Objects, arrays, strings, numbers, booleans and null are supported, including empty collections and nested values.
Does conversion preserve string meaning?
Yes. Values that could otherwise look like YAML booleans, numbers or nulls are quoted so they remain strings.
Does this create YAML anchors or comments?
No. JSON has no anchors, tags or comments, so the converter does not invent those YAML-only features.
Is JSON uploaded?
No. Parsing, conversion, copying and downloading happen in your browser.
