Extraction of invoice number from a string column, using matching rules

DE22 — Fri, 14 Nov 2025 14:04:54 GMT

Hello,

Could you, please help me with the situation below:

How can I, extract the invoice number, which starts with S0 and keep only the invoice number - Ex. S0001 00008761.

I should mention that i can find more invoice numbers, into a line and sometime the invoice number might not respect all the number length.

Regex will be your friend for this, but there is inconsistency in your pattern example. If you are literally looking for "S####_########" then the following works:

But as you can see that does not help with situations like:

So if you can use Regex to identify the pattern, you should be able to adapt it. If you need further help. Can you provide the expected output from each line and myself or others can further help. -Jay
