JSON to YAML

How to convert JSON to YAML?

Simply input your JSON in the editor, either by copy-pasting or by browsing and uploading a file, and it will automatically be converted to YAML in the other editor.
You can then either copy the result to your clipboard or download it as a file.
Note: This tool also supports the reverse conversion, from YAML to JSON.

Why convert JSON to YAML?

Converting a JSON document to YAML is often useful when you want to make the data more readable. YAML is appreciated for its human-readable structure.

However, JSON is more commonly used in web applications and APIs, especially for data exchange between servers and clients, due to its lightweight and machine-friendly format.

When you have a large, poorly indented JSON file, it becomes very difficult to read. This tool converts it into well-formatted YAML, making it much more readable.

There can certainly be other reasons to convert JSON to YAML, and if you’re on this webpage, it means you need it!

It is worth noting that JSON data is valid YAML; in principle, the conversion should not change anything! However, we still reformat it into a more readable YAML style 🙂

Why use a JSON to YAML converter?

This YAML converter is basic but super fast compared to generative AIs (but for how much longer...?)
