In Trifacta or Google Cloud Dataprep, i'm trying to flag rows with non alpha numeric (�). What formula do I use? tried this formula but doesn't work
Replace Matches of `�` from EMPLOYEE_FIRST with NOT VALID
Can you clarify what you mean by "doesn't work"?
The following step works for me in Dataprep. You can paste it directly into the New Step wizard:
replacepatterns col: EMPLOYEE_FIRST with: 'NOT VALID' on: `�` global: true
If that does not work for you, can you please post a screenshot of what happens after adding (or trying to add) this step?
