In two-dimensional XLOOKUP formulas, it doesn't matter which way around the XLOOKUPs go. In this example, the ID lookup is first in the formula, and the column header lookup is nested.

The Double X Lookup function stands out due to its ability to perform two-way lookups, a feature that surpasses the limitations of traditional Excel functions like VLOOKUP and HLOOKUP.

The lookup function in Excel can save you a lot of time and effort, but only if you actually know how to use its many forms and alterations.
