Formula for VLOOKUP

=VLOOKUP(value,group_table,column,TRUE)

Explanation of formula

If you need to categorize by number then, you can customize the VLOOKUP function for meeting the requirements. The customization enables a user to create arbitrary groups or intervals for grouping numbers with VLOOKUP. For instance, the above-attached screenshot discusses the age vs. age group of people belonging to several demographics. A user is asked to sort out the given ages into group forms.

Here, Column D illustrates ‘age’ which would be taken into factor along with ‘age’ and ‘group’ columns illustrated in Column G and Column H respectively. Next, a user would enter the equation into Column E, where the age group of a corresponding age would be specified—once the user presses ENTER. Let’s have a closer look at how the formula works:

How does the formula work?

Figure 1 demonstrates the formula bar with the VLOOKUP function. We have used the following formula for sorting group numbers with VLOOKUP custom function:

=VLOOKUP(D5,G5:H8,2,TRUE)

The formula considers the value of D5 as its lookup value. Next, it focuses on G5:H8 as its age_table. Here, 2 indicate that the values are the location in the 2nd column index (Column H). Last but not least, we add TRUE to the equation which serves the purpose of approximate match mode in the equation.

Once we have entered an enclosed the variables and functions—the VLOOKUP function with the scan through the age group, and it would scan the corresponding group name from the 2nd index column. The column can contain customizable text or numeric values as per the preference of the user. Let’s have a look at the following example for understanding the uniqueness and versatility of the formula:
