Convert YAML to JSON
Parse YAML files into strict JSON for APIs, validation and tooling.
What happens when you convert YAML to JSON
Parses YAML and emits strict, indented JSON. This is the direction to go when a tool, API or validator insists on JSON, or when you want to check that a hand-edited YAML file actually parses the way you intended.
Good for
- Feeding a configuration file to an API or schema validator
- Debugging YAML indentation by seeing the structure it really produces
- Converting CI or Kubernetes manifests for tooling that wants JSON
Worth knowing
- YAML comments are discarded — JSON has no way to represent them.
- YAML anchors and references are expanded into their full values.
- Multi-document YAML files, separated by ---, are not supported; convert one document at a time.
YAML to JSON, answered
How do I convert YAML to JSON?
Drop your YAML file into the box above (or click to browse), make sure JSON is selected as the target format, press Convert, then download the result.
Is this YAML to JSON converter really private?
Yes. The conversion runs entirely in your browser — your YAML file is never uploaded to any server, so nobody but you ever sees it.
Is converting YAML to JSON free?
Completely free — no watermarks, no sign-up and no daily quota. Processing happens on your own device, so there are no server costs to pass on to you.
Can I convert multiple YAML files at once?
Yes — drop as many files as you like. Convert them individually or use "Convert all", then download everything as a single ZIP.
