Understand the basic lookup arguments

XLOOKUP requires a lookup value, a lookup array, and a return array. Additional arguments can specify the missing-value response, matching method, and search direction. The source uses this structure as the foundation for lookups involving more than one criterion. Knowing the purpose of each argument makes an advanced expression easier to inspect than memorizing one long formula whose components are unclear.

Check the environment and the intended match

The article notes version requirements, including Excel 2021 or later on desktop and supported web and mobile editions. Confirm compatibility before introducing the function into a shared workbook. Establish the exact record the formula should identify, then decide how multiple requirements will be represented. Test the simplest case first and add complexity only after the original lookup works. This keeps a criteria problem separate from a mismatch in the source and return ranges.
