Excel UPPER Function

While working with Excel, we are able to convert any text string into capital letters by using the UPPER function.  UPPER function converts text into capital letters or uppercase.  This step by step tutorial will assist all levels of Excel users in the usage and syntax of the UPPER function.  

Figure 1. Final result:  Excel UPPER function

Syntax of the UPPER Function


  • text – a text that we want to convert to uppercase; text can be a text string or a cell reference
  • UPPER function does not affect numbers and punctuations

Setting up the Data

Our table consists of two columns: Text (column B) and Result (column C).  Column B consists of a list of phrases or text strings that we want to convert to uppercase.  The results will be recorded in column C.

Figure 2. Sample data to convert to uppercase

Convert to uppercase using UPPER function

In order to convert the text strings in column B into uppercase, we will follow these steps:  

Step 1.  Select cell C3

Step 2.  Enter the formula:=UPPER(B3)

Step 3.  Press Enter

Step 4:  Copy the formula in cell C3 to cells C4:C7 by clicking the “+” icon at the bottom-right corner of cell C3 and dragging it down

Figure 3. Entering the formula using UPPER

The result in cell C3 is the converted text “EXCEL FUNCTION”, consisting of capital letters.  In cells C4 and C5, note that our formula returned the uppercase of the text, without affecting the numbers “1234” or the punctuation asterisk “*”.  

In cell C7, the resulting text “ALPHABET” is the same as the text in B7, because B7 or “ALPHABET” is already in uppercase.
