Trouble Removing Invisible Characters

[Anonymous]

Greetings! 

I am having trouble removing invisible characters. I have tried using the clean/trim function + the REPLACE function but the characters are still there. When I check the length of a row, it is either blank OR 0. This is throwing off my model bc the 0 will not be recognized when I count the number of blank rows. 

Any ideas on how I can remove this? Below is a screenshot and link to sample data.

Hello,

Can you maybe use this logic for the len column:

LENGTH - WCSR = IF(WCSR[TrackingNumber] = BLANK(), 0, LEN( WCSR[TrackingNumber] ))

Meaning, you can use the comparison of the TrackingNumber column values to Blank() to identify which fields are not completed.

If you just want to count the no of blank rows you could try the countblank function.
