JSON to YAML Converter
Convert between JSON and YAML in either direction — useful for Kubernetes manifests, CI config, and any API that accepts one format but not the other.
Conversion happens entirely in your browser — nothing you paste here is uploaded anywhere.
Processing happens locally in your browser. Nothing you enter is uploaded.
How It Works
Choose a direction, paste your JSON or YAML, then click Convert. Use the Swap button to flip direction using the current output as the new input.
Example
{"name":"Alice","tags":["admin","beta"]} converts to: name: Alice tags: - admin - beta
