JSON and YAML Converter
Move configuration between JSON and YAML with a two-way converter that preserves structure. Kubernetes manifests, CI configs, and API settings can all move freely between the formats.
Using the JSON ↔ YAML Converter: step by step
- Choose JSON to YAML for more readable output, or YAML to JSON for stricter machine format.
- Paste your document into the source panel.
- Press convert and review the result in the output panel.
- Copy the converted configuration into your project files.
What people use the JSON ↔ YAML Converter for
- Turning JSON config into YAML for Kubernetes or CI pipeline definitions.
- Converting YAML settings into JSON for tools that only accept it.
- Simplifying a dense JSON file into readable YAML for review.
- Checking whether a YAML edit still matches the original JSON structure.
Inside the JSON ↔ YAML Converter
The converter parses the full YAML feature set, including nested maps, sequences, and inline values, and serializes JSON back into indented block-style YAML rather than flow style. Conversion preserves key order and data types, including numbers, booleans, and null, so round trips are stable. Both parsers run client-side, keeping infrastructure configuration with internal hostnames or tokens off the network.
Limitations worth knowing
YAML anchors and aliases are resolved during conversion; their reuse structure will not reappear identically in the output.
JSON ↔ YAML Converter FAQ
Is YAML output indented or flow style?
Block style with indentation, the readable form most projects standardize on.
Does it support YAML lists and nested maps?
Yes, the full common YAML structure converts in both directions.
Is my configuration sent anywhere?
No. Conversion is local, which keeps deployment manifests and tokens private.
