YAML to JSON
Convert YAML config files into JSON and catch indentation mistakes.
JSON to YAML
Turn JSON into YAML for config files. It happens in your browser.
Your files stay with you. Your files never leave your browser. This tool runs on your device: nothing is uploaded to our servers, so there is nothing for us to store or see.
How to use it
- Paste JSON or open a .json file.
- Pick the indentation and whether to sort keys.
- Copy the YAML or download data.yaml.
Questions people ask
Will the YAML mean exactly the same as my JSON?
Yes. Strings that could be mistaken for numbers or booleans, such as "true" or "411001", are quoted so they keep their type.
Why is my JSON rejected?
It must be strict JSON: double quotes, no comments, no trailing commas. The error tells you the line and column.
Does it keep the order of keys?
Yes, unless you turn on Sort keys.
Is my data uploaded?
Your text is processed in your browser and never sent to our servers.
