Is index match or Sumifs faster?
From a purely speed perspective LOOKUP and INDEX-MATCH (type 1) are the fastest, followed by INDEX-MATCH (type 0), with SUMIFS the slowest as it is required to scan the entire criteria range whilst the other functions stop once they find a match.
How do I use index match instead of Vlookup?
Why use INDEX MATCH instead of VLOOKUP?
- To get the same result using INDEX MATCH, you need to apply the formula =INDEX($C$2:$C$9,MATCH(F2,$A$2:$A$9,0)) to cell G2.

What does the match function do in Excel?
The MATCH function searches for a specified item in a range of cells, and then returns the relative position of that item in the range. For example, if the range A1:A3 contains the values 5, 25, and 38, then the formula =MATCH(25,A1:A3,0) returns the number 2, because 25 is the second item in the range.
