JSON <-> YAML Converter
About JSON & YAML
Developers and DevOps engineers frequently need to switch between data formats. JSON (JavaScript Object Notation) is the standard for APIs and web data, while YAML (YAML Ain't Markup Language) is preferred for configuration files (like Kubernetes, Docker, and Ansible) due to its readability.
How to use: Paste your JSON code on the left to convert it to YAML on the right, or paste YAML on the right to convert it to JSON on the left. The tool uses a robust parsing engine to ensure accuracy.
Frequently Asked Questions
Does this support arrays?
Yes, complex nested structures including arrays and objects are fully supported.
Is my data sent to a server?
No, all conversion happens locally in your browser using JavaScript.
What if my JSON is invalid?
The tool will display an error message below the text area indicating that parsing failed.
Can I convert large files?
Yes, as long as your browser doesn't freeze, you can convert thousands of lines of code.
Is spacing preserved?
We output standard 2-space indentation for both formats.
Can I use this for Kubernetes files?
Absolutely, it is perfect for converting k8s manifests between formats.
