Oh did you see the screen that I attached? that contains special some special characters, however those characters are also present in other values and pivot was not repeating those !
I meant to say non printable characters like like CHAR 160 127 etc, which cant be seen through naked eyes, we need to use a formula, have you imported the data from any DBMS or SAP or any ERP?
SUBSTITUTE()Function to substituteCHAR(160)with""in your source for the specific column.
