Splitting House Numbers with letters

I’m processing some data where I have house numbers stored in a String named houseNumber. Usually they are just digits, but sometimes they might have a letter after the number. E.G 1a, 1b, 1c etc…

I want to split houseNumber into two strings. houseNumberNum and houseNumberLet, so in the case of houseNumber being 26b, houseNumberNum would be ‘26’ and houseNumberLet would be ‘b’

I’ve tried various regular expressions with split, but thus far I’ve had no success. Can anyone help please? TIA!

hey @andrewjames

try this,

To get only Numbers/ digits from a string

To get only Alphabets(case insensitive), from a string
System.Text.RegularExpressions.Regex.Replace(yourString, “[^a-z A-Z]”, “”)

Let me know if this helped.



Capital D gets anything, but numbers. Lowercase d is for numbers.


Using Capital D gives me numbers only, which is desired in this case.
Using lowercase d gives me alphabets only.

We are on same page. correct?

Using D will get the Non-Digits , which are getting replaced with NULL
So remaining data will be Numbers only.
