How Do I Convert a Case in Word? 5 Methods to Change Text Case in Microsoft Word (2026 Guide)

This is the fastest and most popular way to change case in Word. The Shift + F3 shortcut has been available since Word 97 and works in every version of Word for Windows.

Step-by-Step Instructions

1. Select the text you want to convert. You can select a single word (double-click it), a sentence (Ctrl + click), a paragraph (triple-click), or the entire document (Ctrl + A).
2. Press Shift + F3 once. Your text will change to the next case in the cycle.
3. Keep pressing Shift + F3 to cycle through the available options until you reach the one you want.

What the Cycle Looks Like

Limitations of Shift + F3

• Only 3 options: It cycles through lowercase → Sentence case → UPPERCASE. No Title Case or tOGGLE cASE.
• No style-guide awareness: Sentence case detection is basic — it capitalizes the first letter after a period but doesn’t recognize proper nouns.
• Can’t do developer formats: No camelCase, PascalCase, snake_case, or kebab-case.

The ribbon’s Change Case button gives you access to 5 case options — two more than the keyboard shortcut. This is the method most people should use when they need Title Case or tOGGLE cASE.

Step-by-Step Instructions

1. Select the text you want to convert.
2. Go to the Home tab on the ribbon.
3. In the Font group, click the Change Case button (it looks like Aa with a small dropdown arrow).
4. Choose from the dropdown menu:

Word’s Find & Replace (Ctrl + H) can do more than swap words — it can also change the formatting and casing of matched text. This is powerful when you need to change specific words or phrases to a different case without affecting the rest of your document.

Step-by-Step: Convert Specific Text to UPPERCASE

1. Press Ctrl + H to open Find & Replace.
2. In the Find what field, type the text you want to change (e.g., important notice).
3. In the Replace with field, type the replacement in your desired case (e.g., IMPORTANT NOTICE).
4. Click More >> to expand options.
5. Check “Match case” if you want the search to be case-sensitive.
6. Click Replace All to change every occurrence in the document.

Pro Tip: Use Wildcards for Pattern-Based Conversion

Enable “Use wildcards” in Find & Replace to match patterns. For example, you can find all text inside quotation marks and replace it with an uppercase version — useful for converting dialogue or quoted terms in legal documents.

For power users who need to automate case conversion across multiple documents, tables, or specific elements (like all headings), VBA macros offer unmatched control.

How to Open the VBA Editor

1. Press Alt + F11 to open the Visual Basic Editor.
2. Go to Insert → Module.
3. Paste the macro code below.
4. Press F5 to run.

Macro: Convert Selected Text to Title Case

Sub ConvertToTitleCase()
    If Selection.Type = wdSelectionNormal Then
        Selection.Range.Case = wdTitleWord
    Else
        MsgBox "Please select some text first.", _
               vbExclamation, "No Selection"
    End If
End Sub

Macro: Convert All Headings to UPPERCASE

Sub ConvertHeadingsToUpperCase()
    Dim para As Paragraph
    For Each para In ActiveDocument.Paragraphs
        If Left(para.Style, 7) = "Heading" Then
            para.Range.Case = wdUpperCase
        End If
    Next para
    MsgBox "All headings converted to UPPERCASE!", _
           vbInformation, "Done"
End Sub

Macro: Convert Entire Document to Sentence Case

Sub ConvertDocToSentenceCase()
    ActiveDocument.Content.Case = wdTitleSentence
    MsgBox "Entire document converted to Sentence case!", _
           vbInformation, "Done"
End Sub

Available VBA Case Constants

Microsoft Word offers 5 case options. A dedicated online case converter offers 15+ formats — including developer formats that Word simply cannot do. If you need camelCase, snake_case, PascalCase, kebab-case, CONSTANT_CASE, or dot.case, this is the only option.

How It Works

1. Open onlinecaseconvertor.com in any browser.
2. Paste your text from Word (or type directly).
3. Click the case format button you need.
4. Copy the result with one click and paste it back into Word.
