Filtering Emails

[Del235]

I've created a table that contains email addresses and I don't want to include certain domains.  If I have addresses that appear as johndoe@test.com, I've used an Filter Type : Advanced Filter and Show Items When the Value:  Does Not Contain test.com.

This has no effect.

Why?  How do I filter out test.com?

Hi @Del235

Can you try trimming the column to remove possible whitespace?

CleanEmail = TRIM(CLEAN(LOWER('Table'[Email])))
 
the create a new column:
Test =
NOT CONTAINSSTRING('Table'[CleanEmail], "test.com")

Use Test = True for filtering.

Hi @Del235 ,

I tried to recreate your scenario in Power BI, and on my end the “Does not contain test.com” filter is working as expected. This usually indicates that the behavior might be related to how the data is formatted rather than the filter logic itself. 

First, you can check for hidden spaces or characters in the email values, as these can sometimes affect filtering. You can validate this by creating a column like Length = LEN(YourTable[Email]) if similar emails return different lengths, it likely means there are trailing spaces or invisible characters. 

Secondly, avoid such issues, you can clean and standardize the data by creating a column like Clean Email = LOWER(TRIM(YourTable[Email])), and then use Is Test Domain = CONTAINSSTRING([Clean Email], "test.com"). Applying the filter on this cleaned column generally resolves these inconsistencies. 

Please find the screenshots below for your reference:

@Del235 this should work though, can you create a column and put it in the table to see if you get true or false:

Is Exist = CONTAINSSTRING(YourTable[YourEmailAddressColumn], "test.com")
