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**

`=`

**UPPER**(**text**)

**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.
