URL-Encoded Input

Decoded YAML Output

What is YAML URL Decoding?

YAML URL decoding reverses the percent-encoding process, converting sequences like %3A back to colons and %0A back to newlines, recovering the original YAML string. It is the inverse of URL encoding and is essential whenever you receive YAML data from a URL query parameter or API endpoint.

According to RFC 3986, all characters that cannot appear literally in a URL are percent-encoded during transmission. This tool uses JavaScript's decodeURIComponent() to restore those characters to their original form, giving you back clean, readable YAML.

This tool uses JavaScript's native decodeURIComponent() function to restore percent-encoded sequences back to their original characters. It handles all standard RFC 3986 percent-encoded sequences, recovering the original YAML content with its colons, indentation, and special characters intact.

How to Decode URL-Encoded YAML

Follow these steps to decode your URL-encoded string back to YAML.

Paste the URL-Encoded String

Paste the percent-encoded string into the left panel. Click Sample to load an example. Example encoded YAML:

name%3A%20John%20Doe%0Aage%3A%2030%0Aroles%3A%0A%20%20-%20admin

Click Decode

Click the Decode button. The right panel instantly shows the decoded YAML output with all special characters restored.

Copy the Decoded YAML

Click Copy to copy the decoded YAML to your clipboard. You can then paste it into your editor, config file, or YAML tool.

When You'd Use YAML URL Decoding

API Response Parsing

Decode YAML data received in URL-encoded form from API responses or query parameters. Restore the original YAML structure before parsing or editing.

Webhook Debugging

Decode URL-encoded webhook payloads containing YAML. Inspect the decoded content to debug webhook integrations and configuration issues.

Configuration Recovery

Recover YAML configurations that were encoded in URLs for sharing. Decode them back to readable form before applying to your systems.

Log Analysis

Decode URL-encoded YAML found in server logs or request traces. Restore the original YAML for easier reading and analysis.

Frequently Asked Questions

What if the decoding fails?

If the input contains malformed percent sequences (like %GG which are not valid hex), decodeURIComponent() will throw an error. The tool shows an error message in that case.

Does decoding validate the YAML?

No. This tool decodes the URL encoding and returns the resulting string. It does not validate whether the decoded output is valid YAML. Use our YAML Validator for validation.

Is this the reverse of YAML URL Encode?

Yes. YAML URL Decode is the exact inverse of YAML URL Encode. Encoding converts YAML to percent-encoded form; decoding converts it back.

Is my data sent to a server?

No. All decoding happens in your browser using JavaScript's decodeURIComponent(). Your data never leaves your device.

Can I decode any URL-encoded string, not just YAML?

Yes. The tool uses standard URL decoding, so it works on any percent-encoded string. The output may or may not be valid YAML depending on the input.
