MATCH and VLOOKUP both perform this search activity. INDEX, in comparison, retrieves a value from a range of cells, and is exceptionally fast. Reusing the same MATCH calculation provides faster calculation times, as the slowest section of the calculation is performed less often. index match vlookup faster

INDEXMATCH Is Faster Than VLOOKUP. That is, INDEXMATCH is only about 3 faster. With sorted data and an approximate match, INDEXMATCH is about 30 faster than VLOOKUP. With sorted data and a fast technique to find an exact match, INDEXMATCH is about 13 faster than VLOOKUP. On a 100, 000 row lookup table, a VLOOKUP or MATCH looking for an exact match needs to search 50, 000 rows on average. The binary search form, however, only needs to search 18 rows. Even if you need to search twice (as shown in the formulas below), you still get over 1000X improvement in speed with binary search.index match vlookup faster Approximatematch VLOOKUP is very fast.
