How to Use:

Paste your YAML content into the Input YAML box. If you already have it in a file, use the Choose File button to upload a .yaml, .yml, or .txt file. As soon as you enter valid YAML, Convert YAML to JSON processes it automatically and shows the result in the JSON Output box.

The output updates instantly and flashes when new data is generated. You’ll see the character count update live just beneath the output. You can click Copy Output to copy the result to your clipboard, or Export to File to download it as a .json file. Want to start over? Just hit Clear All to reset everything and reload the converter.

What Convert YAML to JSON can do:

It’s a fast and reliable tool that takes any YAML structure from simple key-value pairs to nested objects and arrays and converts it into clean, properly formatted JSON. It uses a secure in-browser parser, so your data never leaves your device. Whether you’re working with config files, Kubernetes specs, or any other YAML-based format, this tool handles it effortlessly.

Example:

Input:

codename: Alice
email: [email protected]
active: true

Output:

{
  "name": "Alice",
  "email": "[email protected]",
  "active": true
}

Common Use Cases:

Convert YAML to JSON is perfect for developers who need to translate between YAML and JSON without installing CLI tools or writing scripts. Whether you’re debugging an API, formatting config files, or bridging formats between systems, it gives you accurate results instantly. It’s also useful when collaborating with teams that work across both formats.

Useful Tools & Suggestions:

To get things cleaned up before converting, Prettify JSON can be used right after the switch for better readability. And if you’re working with multiple formats, Convert JSON to Properties helps flip the structure again when you need it in a different config style.
