Understand the job shared by the functions

VLOOKUP, XLOOKUP, and the INDEX-MATCH combination all locate related information, but they express the task differently. The source explains INDEX as the retrieval component and MATCH as the position-finding component, then compares the combined approach with dedicated lookup functions. Understanding those roles helps determine whether a formula matches the arrangement of the table instead of choosing a method only because its name is familiar.

Choose the behavior deliberately

Look at where the searched values and returned information sit, how matching should work, and which Excel versions need to use the file. An existing lookup may be perfectly adequate, while another structure may benefit from a more flexible alternative. Check the relevant syntax and test a known record before changing the workbook. A newer function is useful when it addresses the actual constraints, not merely because it can replace an older expression.
