## Filter unique distinct records (case sensitive) [UDF]

The User Defined Function demonstrated above extracts unique distinct records also considering upper and lower case letters. For example, a record containing A and B is not the same as a record containing a and b.

A User defined Function is a custom function anyone can build, you simply add the VBA code to your workbook and you are good to go.
