in data pump pro 10.5 I used the below keywords (on exporting the data to xlsx)
when I transferred it to v12 the [counter] isn't working anymore in it (everything else does).
is there a replacement keyword I can use that did the same thing (GUID or anything unique). I just want to make sure it creates a new file no matter what. so that counter helped to make sure it would never overwrite or append data to a xlsx file.
