How To Change Capital Letters To Lowercase In Excel

How To Articles

When it comes to working with data in Excel, there are often various formatting tasks that need to be performed. One common task is converting capital letters to lowercase, and in this article, I’ll walk you through the process. This is a simple yet essential function that can make your data more consistent and easier to analyze.

Using the LOWER Function

One way to change capital letters to lowercase in Excel is by using the LOWER function. This function converts all capital letters in a specified cell or range of cells to lowercase. Here’s how you can use it:

  1. First, select the cell where you want the lowercase text to appear.
  2. Then, enter the formula =LOWER(cell_reference), replacing cell_reference with the reference to the cell containing the text you want to convert. For example, if your text is in cell A1, the formula would be =LOWER(A1).
  3. Press Enter, and the text in the selected cell will be converted to lowercase.

Using the Text to Columns Feature

Another method to change capital letters to lowercase is by using the Text to Columns feature. This method is helpful when you want to change the case of an entire column of data. Here’s how you can do it:

  1. Select the column that contains the text you want to convert.
  2. Navigate to the “Data” tab in the Excel ribbon and click on “Text to Columns.”
  3. In the “Convert Text to Columns Wizard,” choose “Delimited” and click Next.
  4. If you don’t have a delimiter, you can choose “Fixed width” and click Next to skip this step.
  5. In the third step, if you see the “Column data format” shows “General,” select the column and change it to “Text” to ensure that the case doesn’t change.
  6. Click Finish to apply the changes, and your text will be converted to lowercase.

Using a Formula with the EXACT Function

You can also use a formula that incorporates the EXACT function to achieve the same result. This method allows you to maintain the original data and display the lowercase version in a separate column. Here’s a step-by-step guide:

  1. Create a new column next to the one containing the text you want to convert.
  2. Enter the formula =LOWER(A1) in the first cell of the new column, where A1 is the reference to the cell containing the original text.
  3. Drag the fill handle down to apply the formula to the entire column.
  4. To ensure the case changes dynamically if the original data is altered, you can use the EXACT function. In another adjacent column, enter the formula =EXACT(A1,B1), where A1 is the original text cell and B1 is the corresponding cell in the lowercase column.
  5. This will return TRUE if the lowercase version matches the original text, allowing you to identify any discrepancies.


In this article, I’ve covered multiple methods for changing capital letters to lowercase in Excel. Whether you opt for the simplicity of the LOWER function, the versatility of Text to Columns, or the dynamic nature of a formula with the EXACT function, you have various options to suit your specific data formatting needs. By incorporating these techniques into your Excel repertoire, you can ensure that your data is consistently formatted and ready for analysis.
