How to Convert Small Letter to Capital Letter in Excel: A Guide

Converting small letters to capital letters in Excel is a simple task that can be done using the UPPER function. This function changes all lowercase letters in a text string to uppercase. To do this, you will need to use a formula that includes the cell reference of the text you want to convert.

Step by Step Tutorial: How to Convert Small Letter to Capital Letter in Excel

Before we dive into the steps, let’s clarify what we’re about to do. We will use the UPPER function in Excel to convert lowercase text in a cell to uppercase. This function is handy when you want to standardize the text for presentations or reports.

Step 1: Select the cell where you want the capital letters to appear

The first thing you need to do is click on the cell where you want the converted text to be displayed. This cell will contain the formula that converts the text from another cell to uppercase.

When you select the cell, make sure it’s not the same cell that contains the lowercase text you want to convert. If you do that, you’ll overwrite the original text, and we don’t want that!

Step 2: Type the UPPER function formula

Next, you’ll need to type in the formula “=UPPER(cell reference)” without the quotation marks. Replace “cell reference” with the actual cell reference that contains the text you want to convert.

For example, if the text you want to convert is in cell A1, the formula would be “=UPPER(A1)”. Make sure to include the parentheses and the cell reference inside them.

Step 3: Press Enter to apply the formula

After typing in the formula, hit the Enter key on your keyboard. The text in the referenced cell will instantly be converted to uppercase and displayed in the cell where you entered the formula.

Remember, the original text in the referenced cell won’t change. It will remain in lowercase, but the text in the new cell – where you input the formula – will be in uppercase.

After you complete the action, the cell with the formula will display the text in uppercase. Any changes made to the original text will automatically update the uppercase version, thanks to the dynamic nature of Excel formulas.

Tips: Converting Small Letter to Capital Letter in Excel

  • Make sure you’re referencing the correct cell in your UPPER function formula.
  • The UPPER function will not affect numbers, special characters, or spaces – only letters.
  • If you want to convert multiple cells to uppercase, you can drag the formula down or across to apply it to other cells.
  • To quickly change the case of text in Excel without using a formula, you can use the “Change Case” feature in the Excel ribbon under the “Home” tab.
  • Remember that the UPPER function formula will not alter the original text, so if you want to replace the lowercase text with uppercase permanently, you’ll need to copy the uppercase text and use “Paste Values” to overwrite the original text.
