What is it?
The pattern match filter provides the option to use regex to trim the results of a column down to only the pattern/text you are looking to retain.
How is it used?
Add Table Filter > Fill, Replace & Overwrite > Find Pattern Matches
To use the find pattern matches filter, simply specify the column you would like to target, then input a regular expression to match what you are looking for. More information on Regular Expressions (regex) can be found here.
