Hi Paul,
The standard approach would normally be to wrap a MATCH() function inside an INDEX() function. i.e.
However I suspect this is not working because (most of ) your plan descriptions are in excess of 300 characters and I guess Excel doesn't like this.
I note that many of the strings are the same at various lengths. For instance at the first 10 characters level, 5793 of the 6326 strings are identical. It may be possible to break these down in some way to overcome what appears to probably be a 256 character restriction.
If you can give us some idea of the algorithm for producing the plan descriptors it may be possible to do something further.
