In this Excel lesson you will teach yourself how to create a case sensitive vlookup. This is a clever way to solve many problems caused by caps lock keyboard button.

## Case-sensitive vlookup

Vlookup function doesn't care about case-sensitivity. So what to do when you do?

This is an example:

The task is to vloookup the value to the word. Formula should care about case-sensitivity.

The solution is this array formula:

**=VLOOKUP(value,IF(EXACT(value,column),table),column_number,0)**

0 here means the exact match for the vlookup function.

Formula in the example is:

**{=VLOOKUP($D2,IF(EXACT($D2,$A$2:$A$10),$A$2:$B$10),2;0)}**

Please be aware that it is an array formula so you need to use **CTRL + SHIFT + ENTER** keyboard shortcut. That's why there are braces around the formula. They appears after you typed CTRL + SHIFT + ENTER.

## Case-sensitive lookup

The problem is that your data differ only by case so capitalization is important for you. That's why you need case sensitive lookup. Let's construct a formula which will solve your problem. INDEX formula suits the best. Syntax here will be:

**=INDEX(value_you_need, row_number, column_number)**

**value_you_need**is a data range from your data table**row_number**- this is hard to get. You have to use EXACT function for case sensitive function**column_number**is always 1

In this example you need the **Price** and you have **Product ID**s. The formula you need is:

=INDEX(B1:B5;SUMPRODUCT((EXACT(A1:A5;E2))*(ROW(A1:A5)));1)
