I want to Merge column Number to table 1. Is there a way to use VLOOKUP with multiple matching criteria

Answer 1

Yes. You can create a helper column in source table to provide unique identifiers for VLOOKUP() by concatenating individual identifiers like this:

=$A1&$B1

And then you perform VLOOKUP() with multiple criteria like this:

=VLOOKUP($B1&$C1,...)

Answer 2

Use Index/Match as an array formula ( Ctrl-Shift-Enter after inputting formula)

{=INDEX(A7:A10,MATCH(B2&C2,B7:B10&C7:C10,0))}

Paste this in your Table 1
