JSON to YAML converter
Turn JSON into clean, human-friendly YAML for config files, Helm values or docs. Strings that YAML would otherwise misread are quoted for you.
Loading the tool…How to use it
- Paste JSON or drop a .json file.
- Choose indentation and key sorting.
- Copy or download the .yaml.
Private by design
The conversion runs as JavaScript in this tab. Your data is not uploaded, logged or stored. There is no account and no file-size paywall.
Safe quoting
A JSON string such as "on", "1.0" or "2024-01-01" would change meaning if written bare in YAML. The converter quotes these values so the YAML loads back to exactly the same data.
Questions
Is my file uploaded anywhere?
No. The file is read by JavaScript in this tab and never leaves your device. You can load the page, switch off Wi-Fi and it keeps working.
Is the output valid for Kubernetes and Docker Compose?
Yes. It is standard YAML; the structure mirrors your JSON exactly.
Can I convert back?
Use the YAML to JSON converter.
