Filtering from Power Query - (with clear example)

[rowingblazers]

Hello,

I have a column with a list of data that I want to organize by certain cities.

So what I have right now is something similar to

NY59V9
NJ47W3
SF111A3

339TX

94CT28

As you can see my dataset is a mix of number/random alphabets+ two state abbrevation. 
I would like to only extract those Abbreviation and create a new column but I just can't really figure out how. 

NY

NJ

SF

TX

CT

Can anyone give me some advice?
Please let me know if you have any question. 

Best,
KP

Use following formula in a custom column. Replace Data with your column name.

=Text.Start(Text.Select([Data], {"A".."Z"}),2)
