The Find & Replace tool in Word does the work for you
Open the Find & Replace dialog by pressing Ctrl+H on Windows or Command+Option+F on Mac. Type the word you want to find in the "Find what" field and the replacement word in the "Replace with" field. Click "Replace All" to change every instance at once, or "Replace" to change them one at a time and review each match first.
The tool works across your entire document, headers, footers, and footnotes. It is faster and more reliable than scrolling through and editing by hand, especially in long documents where you might miss instances or make typos.
Key Takeaways
- Press Ctrl+H (Windows) or Command+Option+F (Mac) to open Find & Replace without navigating menus.
- Use "Replace All" to change every instance of a word throughout your document in seconds.
- Use "Replace" one at a time if you need to check each match before changing it, in case the word appears in different contexts.
- The "Match case" option lets you replace only lowercase or uppercase versions, and "Whole words only" prevents replacing parts of longer words.
- You can undo all replacements at once by pressing Ctrl+Z when ready after, even if you replaced hundreds of instances.
Replace All vs. Replace One at a Time
"Replace All" changes every match in your document when ready. Use this when you are certain the word means the same thing everywhere — for example, replacing a company's old name with its new name throughout a report.
"Replace" (without "All") stops at each match and asks you to confirm. Use this when the word might appear in different contexts. For instance, if you search for "bank," you might find "bank account," "river bank," and "blood bank" — and you may not want to replace all of them the same way.
After you click "Replace," Word highlights the next match. You can click "Replace" again to change it, or "Find Next" to skip it and move to the next one without changing anything.
Using Match Case and Whole Words Only
Match case makes the search sensitive to uppercase and lowercase letters. If you search for "Word" with Match case on, it will find "Word" but not "word." This is useful when you want to replace a proper noun or the start of a sentence without affecting the same word in lowercase elsewhere.
Whole words only prevents the tool from replacing parts of longer words. If you search for "read" without this option, it will also change "reading," "reader," and "already." With "Whole words only" turned on, it changes only the standalone word "read."
Both options sit as checkboxes in the Find & Replace dialog. Check them before you type your search term, or check them after — the order does not matter.
Finding and Replacing Special Characters and Formatting
You can replace more than just words. Click "More options" (or "Format" on some versions) to search for and replace text that has specific formatting — bold, italic, a particular font, or a certain color.
To replace a line break, paragraph mark, or tab, use special codes: type ^p for a paragraph break, ^t for a tab, and ^l (lowercase L) for a line break. These codes work in the "Find what" and "Replace with" fields. For example, you could replace every paragraph break followed by a space with just a paragraph break, cleaning up accidental double spacing between paragraphs.
Regular expressions (a more advanced search method) are available under "More options" if you enable them. This lets you search for patterns rather than exact text — for instance, finding any number or any word that starts with a capital letter. Most users do not need this feature for everyday work.
Undoing a Replace All if You Made a Mistake
If you click "Replace All" and when ready realize you made a mistake, press Ctrl+Z right away. Word will undo all the replacements at once, even if you replaced hundreds or thousands of instances. This works only if you have not made any other edits since the replacement.
If you have made other edits since, you can still undo, but you will undo those edits too. In that case, it is faster to use Find & Replace again to change the words back to what they were before.
Replacing Text in Headers, Footers, and Comments
Find & Replace searches headers and footers automatically — you do not need to do anything special. If your document has a header that appears on every page, and you replace a word there, it changes on every page at once.
The tool also searches tracked changes and comments. If you have comments in your document and you replace a word that appears in a comment, the replacement happens there too. This can be useful if you are cleaning up a document before sending it out, but it also means you should review what gets changed if comments are important to your workflow.
Replacing Across Multiple Documents
Find & Replace works on one document at a time. If you need to replace a word in multiple files, open each document and run Find & Replace separately, or use Word's "Open" dialog to open multiple documents in separate windows and switch between them.
Some versions of Word allow you to search in a folder of documents without opening each one individually — look for "Find in" or a folder search option in the Find & Replace dialog. The exact location varies by Word version and whether you are using the desktop app or the web version.
Frequently Asked Questions
Can I replace a word with nothing to delete it?
Yes. Leave the "Replace with" field empty and click "Replace All." Word will remove every instance of that word. Be careful with this — it is straightforward to delete something you meant to keep. Use "Replace" one at a time if you are unsure.
What if I want to replace a word only in a specific part of my document?
Select the text you want to search in before opening Find & Replace. The tool will then search only within your selection. If you do not select anything, it searches the entire document.
Why does Find & Replace not find a word I know is in my document?
Check for extra spaces before or after the word you typed in the "Find what" field — a space counts as a character. Also check that "Match case" is not turned on if the word appears in a different case than what you typed. If the word is hyphenated or contains special characters, make sure you typed it exactly as it appears.
Can I replace text with a different font or color?
Yes, but only in newer versions of Word. Click "Format" in the Find & Replace dialog, choose the formatting you want the replacement text to have, and then run the replacement. The new text will take on that formatting automatically.
Does Find & Replace work the same way in Word Online as in the desktop app?
The basic function is the same — Ctrl+H opens Find & Replace in both. Some advanced options like regular expressions or format replacement may not be available in Word Online. If you need those features, use the desktop version of Word.
