DecodeString

Takes a Base64-encoded string and converts it to a normal string.

Commonly used when receiving Base64-encoded data from an external system, API, or connector — for example, decoding a value pulled from an HTTP response header, an XML/JSON field, or a credential that was Base64-encoded for transport, so it can be read or processed as plain text further downstream in the ruleset.

Example:

• Input: Q2xlbzEyMw==
• Output: Cleo123
