Word Bold All Instances of a Word?

No, Microsoft Word does not have a single button that bolds every occurrence of a specific word at once. However, you can do it in a few steps using the Find and Replace feature with formatting, which takes less than a minute once you know the trick.

How to Bold All Instances of a Word

Here is the exact procedure for Word 2016, 2019, 2021, and Microsoft 365 on Windows. The steps are nearly identical on Mac, with the only difference being that you press Command + H to open Find and Replace.

  1. Press Ctrl + H to open the Find and Replace dialog box.
  2. In the Find what field, type the exact word you want to bold. For example, type important.
  3. Click More >> at the bottom left to expand the dialog box.
  4. Click in the Replace with field.
  5. Click the Format button at the bottom, then choose Font.
  6. In the Font dialog box, under Font style, select Bold. Click OK.
  7. Click Replace All.

Word will now bold every instance of the word you typed in the Find what box. A message will appear telling you how many replacements were made. Click OK, then close the dialog box.

Why This Works

The Find and Replace feature in Word is not limited to text. It can also replace formatting. When you set the Replace with field to have bold formatting, you are telling Word to change the formatting of whatever text matches the Find what field, even though the text itself stays the same. This is why you leave the Replace with field empty of text but apply the Bold font style to it.

This technique works for any formatting, not just bold. You can italicize, underline, change the font color, highlight, or even apply multiple formats at once. For example, if you want to make every instance of a word bold and red, you would set both Bold font style and a red font color in the Replace with formatting.

What About Whole Words vs. Parts of Words?

By default, Word’s Find and Replace will match the word even if it is part of a longer word. For example, if you search for cat, it will also match cat in catalog and concatenate. To avoid this, expand the Find and Replace dialog box (click More >>) and check the box that says Find whole words only. This ensures that only standalone instances of your word are bolded.

You might also want to consider case sensitivity. If you search for Apple with the Match case option checked, it will only bold instances where the word is capitalized exactly that way. If you leave it unchecked, it will bold apple, Apple, and APPLE all at once.

Common Mistakes and How to Avoid Them

  • Forgetting to click in the Replace with field before setting formatting. If you set the bold format while the cursor is still in the Find what field, you will search for bold text instead of replacing with bold text. Always click in the Replace with field first.
  • Leaving the Replace with field empty of text. This is correct. If you accidentally type something there, it will replace your word with that text. Double-check that the field is blank except for the formatting.
  • Not clearing formatting after you are done. If you later try to do a normal find and replace, the bold formatting may still be applied to the Replace with field. To clear it, open Find and Replace, click in the Replace with field, click Format, and choose Clear Formatting.
  • Using Find instead of Replace All. The Find tab only locates occurrences; it does not change them. You must use the Replace tab and click Replace All.

Alternatives: Macros and Styles

If you frequently need to bold a specific word, you might want to use a macro. A macro is a recorded sequence of actions that you can run with a single click or keyboard shortcut. To record a macro that bolds all instances of a word, you would:

  1. Go to View > Macros > Record Macro.
  2. Name the macro (e.g., BoldWord) and assign it to a button or keyboard shortcut.
  3. Perform the Find and Replace steps exactly as described above, but instead of typing a specific word, use the Find what field with a placeholder that you will replace each time.
  4. Stop recording.

However, macros are not ideal for a one-off task because the Find what text is fixed. A simpler alternative is to use Word’s Styles. If you want to bold a word every time it appears in a heading or a specific paragraph style, you can modify that style to be bold. But for arbitrary occurrences throughout the document, the Find and Replace method is the most straightforward.

What About Google Docs?

If you are using Google Docs, the process is similar but not identical. In Google Docs, you can use the Find and Replace feature (Ctrl + H) and then:

  1. Type the word in Find.
  2. Leave Replace with empty.
  3. Click More options (the three vertical dots).
  4. Check Match case if you want exact case.
  5. Click Replace or Replace all.

But wait, this only replaces the text with nothing, which would delete the word. To bold it, you need to use a slightly different approach: after finding the word, you cannot set formatting directly in the Replace with field. Instead, you would need to manually bold each occurrence or use an add-on. The Word method is much more efficient for this specific task.

Limitations and Caveats

This method works on the text as it appears. If the word is already bold, it will remain bold. If the word is partially bold (e.g., one character bold, the rest not), the Replace All will make the entire word bold. Also, if the word appears in a text box, header, footer, or footnote, the Find and Replace will not affect those areas by default. To include them, you need to run the Find and Replace separately in each of those areas.

Another limitation: if the word is part of a hyperlink, the bold formatting may not apply cleanly because hyperlinks have their own style. You may need to unlink the hyperlink first, or manually bold it.

Frequently Asked Questions

Can I bold all instances of a word in a PDF using Word?

No, Word cannot edit a PDF directly. You would need to convert the PDF to a Word document first (using Word’s Open command) and then use the Find and Replace method. Note that the conversion may not be perfect, especially for complex layouts.

Will this method bold the word in headers and footers?

No, by default Find and Replace only works in the main body of the document. You must repeat the process separately for headers, footers, footnotes, and text boxes. To do that, click into each of those areas and run the same Find and Replace.

How do I undo if I accidentally bold too many words?

Press Ctrl + Z immediately after the Replace All to undo the entire operation. If you have made other changes since, you can undo multiple steps by pressing Ctrl + Z repeatedly, or use the Undo dropdown arrow to select the specific action.

Can I bold all instances of a word that appears in different cases (e.g., “Word” and “word”)?

Yes, if you leave the Match case option unchecked, Word will treat all variations as matches. However, be careful: it will also match the word inside other words unless you check Find whole words only.

Is there a way to bold all instances of a word using a keyboard shortcut?

Not directly. You can assign a macro to a keyboard shortcut to automate the Find and Replace, but the macro will only work for the specific word you hard-code into it. For a one-off word, the manual Find and Replace is fastest.
