PowerPoint automatically capitalizes the first letter of every sentence you type. This AutoCorrect behavior can be frustrating when you need to keep the first letter lowercase, such as for product names, code snippets, or specific branding terms. The feature is enabled by default in PowerPoint for Windows and Mac. This article explains how to turn off first-letter capitalization in PowerPoint using the AutoCorrect Options dialog box.
Key Takeaways: Disable First-Letter Capitalization in PowerPoint
- File > Options > Proofing > AutoCorrect Options: Opens the dialog where you uncheck the Capitalize first letter of sentences setting.
- Uncheck “Capitalize first letter of sentences”: Stops PowerPoint from automatically uppercasing the first character after a period, exclamation mark, or question mark.
- Restart PowerPoint after changing the setting: Ensures the new AutoCorrect rule takes effect for all new text you type.
How PowerPoint AutoCorrect Capitalization Works
PowerPoint uses a built-in AutoCorrect list that includes several capitalization rules. The rule “Capitalize first letter of sentences” triggers after you type a period, exclamation mark, question mark, or press Enter twice in a row. When PowerPoint detects the end of a sentence, it changes the next character to uppercase. This rule applies to text boxes, placeholders, shapes, and notes. The setting is stored per user profile, not per presentation. Changing it in one presentation affects all future presentations on that computer.
Steps to Turn Off First-Letter Capitalization in PowerPoint
Follow these steps to disable the AutoCorrect rule that capitalizes the first letter of every sentence.
- Open the AutoCorrect Options dialog
In PowerPoint, click the File tab on the ribbon. Select Options from the left navigation pane. In the PowerPoint Options window, click Proofing on the left. Click the AutoCorrect Options button near the top of the right pane. - Locate the capitalization setting
In the AutoCorrect dialog, ensure the AutoCorrect tab is selected. Look for the check box labeled Capitalize first letter of sentences. It is usually the first check box under the heading “Correct capitalization.” - Uncheck the rule
Click the check box to remove the check mark. Do not change any other settings unless you intend to modify additional AutoCorrect rules. - Confirm and close
Click OK to close the AutoCorrect dialog. Then click OK to close the PowerPoint Options window. - Restart PowerPoint
Close all open PowerPoint windows and reopen the application. The change takes effect after the restart. Test by typing a lowercase word after a period in a text box.
What to Do If the Setting Does Not Take Effect
The first letter still capitalizes after following the steps
If the first letter remains capitalized, the issue may be a different AutoCorrect rule. Open the AutoCorrect Options dialog again and uncheck Capitalize first letter of table cells if you are typing inside a table. Also uncheck Correct accidental use of cAPS LOCK key if you are typing in all lowercase and PowerPoint reverts to uppercase.
PowerPoint capitalizes the first letter after a line break
When you press Shift+Enter to create a soft line break, PowerPoint may still capitalize the next word. This is controlled by the same “Capitalize first letter of sentences” rule. If you uncheck it, soft line breaks should also stop triggering capitalization. If the issue persists, check whether the text box has a style override. Right-click the text box, select Format Shape, and verify no text transformation is applied under Text Options > Text Box.
The setting reverts after closing PowerPoint
This can happen if your user profile is corrupted or if group policies enforce the default AutoCorrect settings. Try repairing Office from Control Panel > Programs and Features > Microsoft 365 > Change > Quick Repair. If the setting still reverts, contact your IT administrator to check for enforced policies.
PowerPoint AutoCorrect Capitalization: Before vs After Disabling
| Item | With Capitalization Enabled | With Capitalization Disabled |
|---|---|---|
| Typing after a period | “The quick brown fox. Jumps over” becomes “The quick brown fox. Jumps over” | “The quick brown fox. jumps over” stays lowercase |
| Typing after a question mark | “Is it ready? Yes” becomes “Is it ready? Yes” | “Is it ready? yes” stays lowercase |
| Typing after an exclamation mark | “Stop! Do not” becomes “Stop! Do not” | “Stop! do not” stays lowercase |
| Typing in a table cell | First letter of each cell capitalizes | First letter remains as typed |
You can now control exactly how PowerPoint handles the first letter of each sentence. If you frequently type brand names or code that require lowercase starts, disabling this single rule saves time. For more precise control, explore the Exceptions list in the AutoCorrect dialog to add specific words that should never be capitalized.
