How it works
In Excel or Google Sheets, change case with a helper column: =UPPER(A2) for ALL CAPS, =LOWER(A2) for lowercase, =PROPER(A2) to capitalize each word — then paste the results back as values. Excel has no Shift+F3 shortcut like Word.
Insert a helper column next to your text.
Use =UPPER(A2), =LOWER(A2), or =PROPER(A2) and fill down.
For sentence case: =UPPER(LEFT(A2,1))&LOWER(MID(A2,2,LEN(A2))).
Copy the helper, Paste Special ▸ Values over the original, delete the helper.
What this does
Excel deliberately has no "Change Case" button; case conversion is done with the three text functions UPPER, LOWER, and PROPER in a helper column. PROPER capitalizes every letter that follows a non-letter, which is right for names ("anna meyer" → "Anna Meyer") but quirky for words with apostrophes or codes ("don't" → "Don'T"). Sentence case needs a small combined formula.
A worked example
Column A holds shouting customer names like "ANNA MEYER". In B2, =PROPER(A2) returns "Anna Meyer"; filling down fixes the whole list. Copy column B, then Paste Special ▸ Values over column A and delete the helper — the originals are replaced in place. Imported data arrives SHOUTING or all-lowercase constantly — CRM exports, form submissions, legacy systems. A helper column with one function call normalizes thousands of rows in seconds.
Common mistakes
- Looking for Word's Shift+F3 — Excel does not have it.
- Deleting the original column before pasting the formulas back as VALUES, which breaks the references.
- Expecting PROPER to handle "McDonald" or "iPhone" — it returns "Mcdonald" and "Iphone".
- Running PROPER over codes like "A-1b" and getting "A-1B" — letters after digits and dashes get capitalized too.
FAQ
Is there a change-case shortcut in Excel?
No. Unlike Word's Shift+F3, Excel needs the UPPER/LOWER/PROPER functions, Flash Fill, or a paste from the converter above.
How do I convert case without formulas?
Type the first corrected value and press Ctrl+E (Flash Fill) — or paste your column through the converter above and copy the result back.
What does PROPER do with apostrophes?
It capitalizes the letter after them: "o'brien" becomes "O'Brien" (good) but "don't" becomes "Don'T" (usually not wanted).
