How to Convert String to GUID in Power Automate?

Assume you need to generate a new globally unique identifier (GUID). In that instance, Power Automate offers the guid(), which generates and returns a new GUID as a string. It is a handy function, however, it does not generate a GUID based on the string we provide.

So, this Power Automate tutorial will explain how to convert a string into a GUID format with dashes (with or without curly braces), unlike the guid() in Power Automate, which generates and returns a new unique identifier.

For example, I will create an Instant cloud flow, and that will trigger manually. Then, it will convert the string to a guid with curly or without curly braces.
