Hey @Data_Alter,

Should row 5 not be PQ872-10 just like row 2 and 3?

[IraWatt · Accepted solution]

@Data_Alter, one option is to use Regex to pattern match and parse the text you want.

this regex for this works on the data you gave as an example:

(PQ.*?-[^-]*|WPL-\D+-\d+|WPL \d+ \d+|WPL\d+-\d+)

The pipe | separates the different pattens in the example. For instance, the first pattern I found was 

PQ.*?-[^-]*

This matches with PQ then any characters before a dash then a dash then any character which is not a dash.

If you want to learn more about Regex the community has some really quick interactive videos on getting to grips with it here https://community.alteryx.com/t5/Interactive-Lessons/tkb-p/interactive-lessons/label-name/Parsing%20...
