Data Validation – is used to validate the Data in a cell/Range. In Data Validation, we have criteria such as List, Whole Number etc. And have custom criteria option where we can give function/formula.
Instead of VLOOKUP, we can use INDEX and MATCH functions. Limits of VLOOKUP is we cannot fetch the data from the left side of the Lookup range. Using INDEX-MATCH, we can fetch the data anyways.
