Power Automate – Custom Connector C# – Remove special characters

A common requirement is the ability to remove special characters from a string. Power automate has some basic string expressions, but to remove a set of special characters from any given string is harder than it should be.

Common solutions:

A big expression with nested replace (less actions but hard to read)

A loop within power automate (lots of actions & not scalable)
