How to Use:

  • Paste a URL-encoded YAML string into the input box or import a .yaml, .yml, or .txt file
  • The tool will automatically decode the input using decodeURIComponent()
  • If the encoded content is valid, you’ll see the readable YAML appear instantly in the output box
  • Click Decode to reprocess the input manually if needed
  • Use Copy Output to copy the decoded YAML to your clipboard
  • Use Export to File to save the decoded YAML as a file
  • Toggle Maximize output to expand the output textarea if your content is long
  • Click Clear All to reset everything, including input, output, filename, and toggle states

What URL-decode YAML can do:

This tool takes YAML that’s been URL-encoded whether it’s been passed in a query string, stored in a database, or sent through an API and decodes it back into standard, readable YAML. It converts encoded characters like %0A (newline), %3A (colon), and others into their plain-text equivalents. This is useful when working with systems that pass YAML via URLs or forms where encoding is necessary. The tool doesn’t interpret or format the YAML it just decodes it, leaving the content exactly as it was originally written. Everything runs right in your browser, safely and instantly.

Example:

Encoded YAML:

name%3A%20Alice%0Aage%3A%2030%0Acity%3A%20London

Decoded Output:

name: Alice
age: 30
city: London

Common Use Cases:

Use this when copying YAML from URLs, webhooks, or API payloads where it has been encoded for safe transport. It’s also handy when debugging input coming from front-end forms or command-line parameters. With this tool, you can immediately see the original YAML content in a human-readable format.

Useful Tools & Suggestions:

After decoding your YAML, it’s a good idea to Validate YAML to catch any issues that might’ve crept in during encoding. And if you’re planning to convert it, Transform YAML into JSON keeps your workflow smooth and consistent.
