What this tool does

YAML Key Sorter gives you a fast, focused way to sort mapping keys recursively while retaining sequence order. Everything runs locally in this tab.

The result is produced only after the input is checked. If the value cannot be processed, the workspace reports a specific error instead of guessing.

Example

z: 3
project:
  name: Codingvila
  active: true
a: 1

Limitations

• Review important output before using it in production.
• Very large inputs remain subject to browser memory limits.
