# Group numbers with VLOOKUP

=VLOOKUP(value,group_table,column,TRUE)

If you need to group by number, you can use the VLOOKUP function with a custom grouping table. This allows you to make completely custom or arbitrary groups.

In the example shown, the formula in F7 is:

=VLOOKUP(D5,age_table,2,TRUE)

### How this formula works

This formula uses the value in cell D5 for a lookup value, the named range "age_table" (G5:H8) for the lookup table, 2 to indicate "2nd column", and TRUE as the last argument indicate approximate match.

*Note: the last argument is optional, and defaults to TRUE, but I like to explicitly set the matching mode.*

VLOOKUP simply looks up the age and returns the group name from the 2nd column in the table. This column can contain any values that you wish.

### Pivot tables

Pivot tables can automatically group numbers, but the VLOOKUP approach allows you to perform completely custom grouping.
