Excel UPPER Function – Overview

UPPER function is one of the many text function in Excel.

What does it do?

It takes a string as the input and converts all the lower case characters in that text string to upper case.

When to Use it?

Use it when you have a text string and you want to convert it all characters into upper case. This can often be the case when you get the data from an external source and you want to clean it and make it consistent.

One example of this could be when you have Product Ids in inconsistent format and you want to make it all in upper case.

UPPER Function Syntax

=UPPER(text)
  • text: This is the text string in which you want to convert lower case characters to upper case.

Examples of Using Excel Upper Function

Here are some practical examples to show you how to use the UPPER function in an Excel worksheet.

Example 1 – Convert text in all Cells into Uppercase

Suppose you have a dataset as shown below where you want to make it consistent and make all the cells text in uppercase.

=UPPER(A2)

Example 2 – Combine Cells While Keeping one Part in Upper Case

Suppose you have the address data as shown below and you want to combine this data.

Excel Upper Function - Example 2 dataset

Since the state code is in lower case, you can use the combination of TextJoin and Upper formula to combine and get the address with state codes in upper case.

Below is the formula that would do this:

=TEXTJOIN(", ",TRUE,A2,B2,UPPER(C2))

Excel Upper Function with textjoin

If you’re using a version where TextJoin function is not available, you can use the below formula (which uses the CONCATENATE function):

=CONCATENATE(A2,", ",B2,", ",UPPER(C2))

  1. Numbers, special characters, and punctuations are not changed by the Upper function.
  2. The UPPER function only affects the lowercase characters of the text string. Any character other than the lowercase text characters is left unchanged.
  3. If you use a null character (or a reference to an empty cell), it will return a null character.
