Power Automate: Remove Characters From A String

A Power Automate flow can remove invalid characters from a file name. There are two approaches to do this: defining a list of non-valid characters and removing them from the file name, or creating a list of valid characters and keeping them in the file name. The flow uses actions such as Compose, Pass, Check, and Filter to achieve this. After creating the flow, it can be tested to ensure it works properly. The flow successfully removes non-valid characters from a string by building an array of characters in the text string and filtering out the non-valid characters. Another approach is to define a list of valid characters and filter out any characters that are not in the list.
