How to Spell Check in Excel (Windows & Mac)

How to Spell Check in Excel (Built-In)

Excel includes a spell checker, but unlike Word, it doesn't run automatically. You need to trigger it manually. Here's how on both platforms.

Windows

1. Select the cells, sheet, or range you want to check. To check the entire sheet, click any single cell.
2. Press F7, or go to Review > Spelling in the ribbon.
3. Excel will stop on each misspelled word and show suggestions. Click Change to accept a suggestion, Ignore Once to skip, or Add to Dictionary for names and technical terms.
4. When it finishes, you'll see "Spell check complete."

Mac

1. Select the cells you want to check.
2. Press ⌘+; (Command + semicolon), or go to Tools > Spelling from the menu bar.
3. Review each flagged word and choose Change, Ignore, or Add.

Tip: If you select a specific range before pressing F7, Excel will only check those cells. If you click a single cell, it checks the entire active sheet starting from that cell.

Excel Spell Check Limitations

Excel's spell checker gets the basics done, but it has some real blind spots:

• No grammar checking — it catches "teh" but not "their is a problem" or "the data are shows"
• One cell at a time — the spell checker moves cell by cell, which is slow on large spreadsheets
• No real-time underlining — unlike Word, you won't see red squiggly lines as you type
• Skips formulas — any text inside formulas (like CONCATENATE results) is completely ignored
• No context awareness — it can't tell if "lead" should be "led" based on the sentence
• Misses proper nouns — product names, company names, and abbreviations get flagged as errors even when correct

For spreadsheets with simple labels, the built-in spell check is fine. But if your cells contain sentences, notes, or client-facing text, you need something smarter. Tools like dedicated grammar checkers fill this gap.

How to Enable AutoCorrect in Excel

Excel also has an AutoCorrect feature that fixes common typos as you type — like changing "teh" to "the" automatically.

Windows

1. Go to File > Options > Proofing.
2. Click AutoCorrect Options.
3. Make sure "Replace text as you type" is checked.
4. You can add custom replacements here — useful for abbreviations you type often.

Mac

1. Go to Excel > Preferences > AutoCorrect.
2. Check "Replace text as you type".
3. Add any custom replacements you need.

AutoCorrect is helpful for common typos, but it only handles a fixed list of replacements. It won't catch grammar errors, contextual mistakes, or typos that aren't in its dictionary.

Better Option: Grammar + Spell Check in Excel with FlowWrite

If you regularly write text in Excel — column headers, notes, comments, client-facing labels — you need more than a basic spell checker. FlowWrite is a lightweight Mac menu bar app that adds AI-powered grammar and spell checking to Excel and every other app on your Mac.

Here's how it works:

1. Select the text in any Excel cell (or multiple cells).
2. Press Tab.
3. FlowWrite corrects spelling and grammar, then replaces the text in place.

Unlike Excel's built-in spell checker, FlowWrite understands context. It knows the difference between "their" and "there," catches subject-verb agreement errors, and fixes awkward phrasing — all in under two seconds.
