tMap replace character if column is not null

The data is writing out like this ["PII"].

I want to remove the [""] and convert it to PII.

In tMap, I have this expression:

(row14.LABELS!=null && row14.LABELS="" && StringHandling.TRIM(row14.LABELS).length() > 0)?row14.LABELS.replaceAll("[", "")

When I run the job, I am getting the hard error of Detail Message: aggregated_row_tAggregateRow_1 cannot be resolved to a variable.

What am I doing wrong in the above expression? Can I please have an example of how to replace those characters I don't want with blanks if there's data. This column data can be null.

Youll have to escape all double quotes and brackets. The following worked for me:

row14.LABELS != null ? row14.LABELS.replaceAll("[\\[\\]\"]","") : null

You are probably getting that error because you're using an assignment operator '=' when you should be using an equality operator '==' in your conditional. (fyi use '==' for object comparisons and .equals() method for string comparison) If all you need to check is for nulls, my conditional should be sufficient.

Thank you so much for your help 😀. This worked. I also appreciate the explanation on when to use == or .equal. I am new to all this.
