JSON ↔ YAML Converter
Convert between JSON and YAML formats
Frequently Asked Questions
Why convert between JSON and YAML?
They describe nearly the same data model, but YAML is easier for humans (indentation, comments) and dominates Kubernetes, GitHub Actions, and Docker Compose; JSON is machine-friendlier and ubiquitous in APIs. Converting between them speeds up debugging, migration, and sharing.
Which directions are supported?
Both JSON → YAML and YAML → JSON. Paste either format and the other appears instantly, preserving key order and nesting. Arrays of JSON objects convert cleanly to YAML lists.
What are the common format errors?
- JSON: single quotes, comments, trailing commas - YAML: tabs for indentation (YAML requires spaces), missing space after `:`, unquoted strings with special characters The tool points to the offending line so you can fix it quickly.
What happens to YAML comments when converting to JSON?
Standard JSON has no comments, so they are dropped. If you need to keep context, store it in an explicit `description` field or switch to JSON5/JSONC, which permit comments.
Is my data uploaded?
No. Conversion is fully client-side, so production Kubernetes manifests and Helm charts are safe to paste.
When should I pick JSON vs YAML?
Configuration files (K8s, CI/CD, Ansible) lean toward YAML because of comments and clarity. API payloads, logs, and cross-language messaging prefer JSON for parser consistency. When you need both, just convert.
