Use Find & Replace to change one word or many at once
The fastest way to replace a word in Microsoft Word is to open the Find & Replace dialog and type the word you want to change and what you want it to become. Word will show you each match one at a time, or you can replace all instances in the document at once. This takes seconds instead of scrolling through manually.
You can reach Find & Replace three ways: press Ctrl+H on Windows or Command+Option+F on Mac, go to the Home tab and click Replace, or use the keyboard shortcut. The dialog box is the same regardless of which method you use.
Key Takeaways
- Press Ctrl+H (Windows) or Command+Option+F (Mac) to open Find & Replace when ready from anywhere in your document.
- Type the word to find in the first field and the replacement word in the second field, then click Replace All to change every instance at once.
- Use Match Case if you need to preserve capitalization—for example, replacing "John" but not "john" in the same document.
- Click Find Next to review each match before replacing it, which prevents accidental changes to words you did not intend to modify.
- Use Whole Words Only to replace "read" without accidentally changing "already" or other words that contain those letters.
Step-by-step: Replace all instances at once
Open your Word document and press Ctrl+H (Windows) or Command+Option+F (Mac). The Find & Replace dialog will appear on the right side of your screen or in a separate window, depending on your Word version.
In the Find field, type the word you want to replace. In the Replace With field, type the new word. For example, if you wrote "colour" throughout a document but need "color" instead, type "colour" in Find and "color" in Replace With.
Click the Replace All button. Word will replace every match in the entire document and show you how many replacements it made. If you want to undo the changes, press Ctrl+Z when ready.
Review each match before replacing it
If you are unsure whether every instance of a word should be replaced, use Find Next instead of Replace All. This lets you see each match highlighted in your document before you decide whether to change it.
Click Find Next to jump to the first match. Word will highlight it in your document so you can see the context. If you want to replace this one, click Replace. If you want to skip it and move to the next match, click Find Next again. Continue until you have reviewed all matches.
This method takes longer but prevents mistakes. For instance, if you search for "read" and the word appears in "already" or "thread," you will see it highlighted and can skip those matches.
Use Match Case to preserve capitalization
By default, Find & Replace ignores capitalization. If you search for "john," it will find "John," "JOHN," and "john" all the same way. If you need to replace only the capitalized version or only the lowercase version, check the Match Case box before you search.
For example, if your document mentions both "John" (a person's name) and "john" (part of a product name), you can replace only "John" by turning on Match Case. This prevents Word from changing the product name by mistake.
Use Whole Words Only to avoid partial matches
When you search for a word, Word normally finds it anywhere it appears—even inside other words. If you search for "read," Word will highlight "read," "already," "thread," and "widespread" all the same way. To find only the standalone word "read," check the Whole Words Only box.
This is especially useful for short words or common letter combinations. For instance, searching for "the" without Whole Words Only will match "the," "there," "them," "weather," and "cathedral." Turning on Whole Words Only ensures you replace only the word "the" by itself.
Common mistakes to avoid
The biggest mistake is clicking Replace All without reviewing what you are replacing. If you search for a short word like "is" or "to," you might accidentally change parts of longer words or create nonsense. Always use Find Next first if you are uncertain, or use Whole Words Only to limit matches.
Another common error is forgetting to clear the Find field from a previous search. If you searched for "apple" earlier and did not clear it, you might accidentally replace "apple" when you meant to replace something else. Always check both fields before you click Replace All.
Do not assume Replace All worked correctly without checking the result. Word shows you the number of replacements it made—if that number seems too high or too low, undo the change with Ctrl+Z and try again with different settings.
Frequently Asked Questions
Can I undo a Replace All if I made a mistake?
Yes. Press Ctrl+Z when ready after Replace All, and Word will undo every replacement at once. If you have made other changes since then, you can still undo, but it will undo those changes too. If you wait too long or close the document, you may not be able to undo.
How do I replace a word only in part of my document?
Select the section of text you want to change before you open Find & Replace. When you click Replace All, Word will only replace matches within your selection. This is useful if you want to change a word in one chapter but not another.
What if I need to replace a word with nothing (delete it)?
Leave the Replace With field empty and click Replace All. Word will remove every instance of that word from your document. Be careful with this—it is straightforward to accidentally delete words you meant to keep.
Can I search for line breaks or special characters?
Yes, but you need to use special codes. In the Find field, type ^p for a paragraph break or ^t for a tab. You can replace these with other characters or leave the Replace With field empty to remove them. Check your Word version's help menu for a full list of codes.
Does Find & Replace work the same way in Google Docs?
Google Docs has a similar feature called Find and Replace, opened with Ctrl+H. It works the same basic way—type what you want to find and what you want to replace it with—but has fewer advanced options like Match Case or Whole Words Only. The core function is identical.
