YAML ↔ JSON Converter
Translate configurations between YAML and JSON layouts instantly. Clean nested schemas with custom spacing.
Bi-directional YAML and JSON Configuration Translation
YAML (YAML Ain't Markup Language) is popular for human-readable configurations (like Docker Compose or Kubernetes charts), whereas JSON is the primary language of REST APIs and client-server communication.
Having a secure tool to translate structures back and forth speeds up development. Because formatting configuration files often exposes database keys, environment secrets, and microservice hosts, running this tool locally on the client-side keeps your architectures safe.
Frequently Asked Questions
Is my data sent to any servers?
No. All YAML parsing and JSON encoding processes are executed locally in your browser using secure client-side code. Your configuration values never leave your computer.
Does the YAML parser support comments?
Yes. When converting YAML to JSON, comments are stripped out (as JSON does not support comments). When converting JSON to YAML, the output is formatted as a clean comment-free YAML document.
What version of YAML is supported?
The converter utilizes the js-yaml engine which fully supports the YAML 1.2 specification, including arrays, dictionaries, scalar types, and multiline blocks.
