Hi, we need to do a “reverse partial lookup”.

i.e. we have a list of old_product_codes (Col A) and new_product_codes (col B).

And we need to know if any of the new_product_codes contain (or equal) any of the old_product_codes

We have found ways of making this work on smaller lists, but we now have 317K new_product_codes and 40,000 old_product_codes.

And any method we have tried has timed out. Or crashed Excel.

If you have any suggestions, we would gladly take a look!

That looks excellent, that'll be our first "power query" so we may be on a bit of a learning curve getting that working!
BUT certainly look forward to getting my teeth into that..............
Thanks
