Hi @Anonymous ,

Thanks for your sharing.

According to your images, I make a sample as following.

I use the formula `=LOOKUP(1,0/FIND(A1,Sheet1!A$1:A$2),Sheet1!B$1:B$2)`

in B1 of Sheet 2 to to find the corresponding values.

If I have any misundertandings, you could let me know.

-------Update--------

If File-1 and File-2 are in one worksheet, you could refer to following.

Based on the image above of my sample, the formula is `=LOOKUP(1,0/FIND(F2,A$2:A$3),B$2:B$3)`

.
