How do I separate the alpha prefix from a text (abc123 or a1234)?

[kskaug1]

I cannot use Text-to-column as the alpha spacing is inconsistent. Is there a
formula that I can use to pull the alpha (or numberic) prefix from a text in
Excel.

Ex:
abc123
ab1234
abcd12345
123abc
12abcde

Thanks!

characters..........
