What is a YAML to JSON Converter?
Kubernetes, CI pipelines and configs speak YAML; APIs and code speak JSON. Hand-converting fails on exactly the things YAML is tricky about — indentation, quoting, type coercion.
A real YAML parser does the conversion, so anchors, nested lists and scalar types come out as correct JSON.
How to use the YAML to JSON Converter
- Paste the YAML.
- Click Convert.
- Copy the JSON.
Frequently asked questions
Why did my “no” become false?
YAML 1.1 coerces yes/no/on/off to booleans — a famous footgun (the “Norway problem”: NO → false). Quote strings that must stay strings.
Are anchors and aliases supported?
Yes — &anchor/*alias references are expanded into the JSON.
Multiple YAML documents (---)?
The first document converts; split multi-doc files first.
Are comments preserved?
JSON has no comments, so they are necessarily dropped.
