The quickest way: use the Format menu

Open your document in Microsoft Word and select the text you want to change. Highlight it by clicking at the start of the text, holding down your mouse button, and dragging to the end. Once the text is highlighted in blue, go to the Format menu at the top of the screen.

Click Format, then look for Text in the dropdown menu. A submenu will appear with options including Uppercase, Lowercase, Capitalize Each Word, Toggle Case, and Sentence case. Click Uppercase and your selected text will change immediately.

This method works in Word for Windows and Word for Mac. The text converts right away — you do not need to confirm or save separately. If you change your mind, press Ctrl+Z (Windows) or Command+Z (Mac) to undo.

Key Takeaways

  • Select the text you want to change by clicking and dragging to highlight it in blue.
  • Go to Format > Text > Uppercase to convert highlighted text to all capital letters.
  • The change happens instantly and can be undone with Ctrl+Z or Command+Z if you change your mind.
  • Word offers other text case options like Lowercase, Capitalize Each Word, and Sentence case in the same menu.
  • This method works the same way in Word for Windows and Word for Mac.

Other case options Word provides

Lowercase converts all text to lowercase letters — useful if you have text in all caps that you want to make smaller. Capitalize Each Word puts a capital letter at the start of every word, which is common in titles. Sentence case capitalizes only the first letter of the sentence and proper nouns, which matches standard writing rules.

Toggle Case flips whatever case the text is already in — if a letter is uppercase, it becomes lowercase, and vice versa. This is less common but useful if you need to reverse a conversion you made by mistake or if you are working with text that has mixed capitalization you want to flip.

What to do if the Format menu does not show Text options

In some versions of Word, the Text submenu location varies slightly. If you click Format and do not see a Text option, look for Change Case instead — it may be listed directly in the Format menu without a submenu. Click it and the same case options will appear.

If you are using an older version of Word or a different application that looks like Word, the menu path might be different. Check your application's Help menu and search for "change case" or "text case" to find the exact location in your version.

Selecting text correctly before converting

The conversion only works on text you have selected. If you select nothing and click Format > Text > Uppercase, nothing will happen. Make sure the text you want to change is highlighted in blue before you go to the menu.

You can select a single word by double-clicking it. You can select a whole paragraph by triple-clicking anywhere in that paragraph. You can select multiple paragraphs by clicking at the start of the first one, holding Shift, and clicking at the end of the last one. You can also select all text in your document by pressing Ctrl+A (Windows) or Command+A (Mac), then convert it all at once.

Converting text in headers, footers, and tables

The Format > Text > Uppercase method works in headers and footers the same way it works in the main document body. Click inside the header or footer area first, select your text, then use the menu. Word treats headers, footers, and table cells as regular text for case conversion purposes.

If you have text in a table cell, select it the same way you would select text anywhere else — click and drag to highlight it, or double-click a single word. Then go to Format > Text > Uppercase. The conversion happens instantly, just as it does in the rest of your document.

Undoing a case change you did not mean to make

If you convert text to uppercase and then realize you wanted to keep it as it was, press Ctrl+Z on Windows or Command+Z on Mac immediately. This undoes the last action. You can undo multiple times if you need to go back several steps.

If you have already saved your document after the conversion, you can still undo by opening the Edit menu and clicking Undo, or by pressing the keyboard shortcut. Word keeps a history of your recent changes. If you closed and reopened the document, the undo history is gone, so you would need to select the text again and convert it back manually using the Format menu.

Frequently Asked Questions

Can I convert text to uppercase without using the Format menu?

Word does not have a keyboard shortcut that works directly for case conversion. You must use the Format > Text > Uppercase menu. However, once you use it once, you can repeat the same action by pressing Ctrl+Y (Windows) or Command+Y (Mac) on newly selected text, which repeats your last action.

What if I want to change only part of a word to uppercase?

Select only the letters you want to change by clicking and dragging across just those characters. Then use Format > Text > Uppercase. Word converts only the selected portion, leaving the rest of the word unchanged.

Does this work in Word Online or Word on my phone?

Word Online has the same Format > Text > Uppercase menu. Word on mobile phones (iPhone, Android) may have a different interface — look for a text formatting menu or three-dot options button. The exact steps vary by device and Word version, so check your app's help section if you cannot find the case conversion option.

Can I set up Word to automatically convert text to uppercase as I type?

Word does not have a built-in setting to auto-convert to uppercase while you type. You must select text after typing it and then use the Format menu. Some third-party add-ons for Word may offer this feature, but they are not part of Word itself.
