There are no "unique lines" in your sample data... at least, not within the normal (computer usage included) meaning of "unique."

Perhaps Limbic~Region's interpretation is correct; IMO that's likely and entirely plausible... but what do you want to do if an account includes multiple, unduplicated lines... as, for example, does 03.

If not, please explain what you really want to do, using more precise language, since another (semi-)plausible interpretation of your description is that you want each unique data element, per account number, included in a single file which includes all account numbers.


Questions containing the words "doesn't work" (or their moral equivalent) will usually get a downvote from me unless accompanied by:
  1. code
  2. verbatim error and/or warning messages
  3. a coherent explanation of what "doesn't work actually means.
