Regex step not obeying uppercase in expression

I am trying to identify when a cell’s text is entirely uppercase and am using the assumption that if the first three characters are uppercase, the rest will be too. In this case it’s a city name.

This should work and does on regex testers, but is not in Parabola.


Looks if the first 3 or 2 (accounting for a space or period) letters are uppercase. I am then replacing those first three characters with a symbol so I can then filter by the symbol in the next step.

Hi @Reid_Sheldon - Happy to help! It looks like that expression should work with our Regex step. Could you please email us at and send us the link to the Flow so we can take a closer look?

okay, sent. thank you
