Formula to split accounting codes in one column into 2 columns

[nobbsl]

Hi there, I'm very new to Alteryx and hoping someone can please  help me with a formula.

I have an excel spreadsheet with various accounting codes in 1 column (see attached).

I need to split the codes into 2 columns based on their leading character i.e. Codes starting with a letter be placed in a new column labelled "Project Code" and codes starting with a number be placed in another column labelled "Cost Centre".

Is anyone able to help me with a formula to do this please?

Thanking you in advance

I am using RegEx to check if the first letter is number of letter.
