Google Sheets is a powerful tool for organizing and analyzing data, and one of the many features it offers is the ability to underline text. Whether you're creating a table of contents, emphasizing certain words or phrases, or just want to make your spreadsheet look more professional, underlining text can be a handy feature to know how to use.

To underline text in Google Sheets, start by selecting the cells that you want to underline. Once you've selected the cells, you can either click on the "Underline" button in the toolbar at the top of the screen, or use the keyboard shortcut Ctrl+U (Cmd+U on a Mac). This will underline all of the text in the selected cells.

If you only want to underline certain words or phrases within a cell, you'll need to use a different method. One way to do this is to use the "Format" menu and select "Text" and then "Underline." This will open up a menu where you can select the text you want to underline. Another way is to use the "Find and Replace" feature, and replace a certain character or word with the same character or word, but with underline.

Once you've underlined the text, you can adjust the formatting as needed. For example, you can change the color of the underline, or make it thicker or thinner. To do this, simply select the underlined text and use the formatting options in the toolbar at the top of the screen.

In conclusion, underlining text in Google Sheets is a quick and easy process that can help you to organize and emphasize important information in your spreadsheets. By following the steps above, you'll be able to underline text in no time.
