How to Type Roman Numerals in Word & Excel (3 Easy Ways)
Roman numerals are the “old-style” numbers made from letters, like I, V, X, L, C, D, M. You’ll see them in outlines, chapter headings, and formal documents.
This guide shows you how to convert normal numbers (1, 2, 3…) into Roman numerals (I, II, III…) using:
- Word (convert one number using a field)
- Word (make a Roman numeral list using automatic numbering)
- Excel (convert many numbers using a formula)
Once you generate Roman numerals in Word or Excel, you can copy and paste them into Google Docs, PowerPoint, emails, and anywhere else.
1-Minute Answer (fastest methods)
- Need ONE Roman numeral in Word (example: 24 → XXIV)?
Use a Word field: Ctrl + F9 → type =24*ROMAN → press F9 - Need a Roman numeral LIST in Word (i, ii, iii or I, II, III)?
Use Numbering: Home → Numbering ▼ → choose a Roman numeral style - Need MANY conversions (a list/column)?
Use Excel: =ROMAN(24) → XXIV or =ROMAN(A1) → fill down
Quick Reference (Word vs Excel)
| What you want | Best method | Where | Steps (short) |
|---|---|---|---|
| Convert one number (e.g., 24 → XXIV) | Field code | Word | Ctrl+F9 → type =24*ROMAN → F9 |
| Create a Roman numeral list (I, II, III / i, ii, iii) | Numbering | Word | Home → Numbering ▼ → choose Roman style |
| Convert many numbers (a list/column) | ROMAN() formula | Excel | =ROMAN(A1) → fill down |
Copy & Paste (quick mini section)
Here are Roman numerals 1 to 10 you can copy instantly:
I II III IV V VI VII VIII IX X
For bigger numbers (like 24 → XXIV), use the Word/Excel methods below so you don’t have to guess.
Convert a number to Roman numerals in Word (Field code)
This method is best when you need one Roman numeral inside a Word document (for example, converting 24 into XXIV).
Important beginner note
You must insert Word’s special field braces using Ctrl + F9.
Typing normal curly braces { } from your keyboard will not work.
Step-by-step (Word Field Code)
- Click where you want the Roman numeral to appear.
- Press Ctrl + F9.
- You should see field braces appear.
- You should see field braces appear.
- Click inside the braces and type:
=24*ROMAN- Replace 24 with your number.
- Replace 24 with your number.
- Press F9 to convert it.
- Example: 24 → XXIV
Common mistakes (Word field method)
- Typed braces won’t work (you must use Ctrl + F9)
- Forgetting to press F9 (the field won’t convert until you update it)
- Putting the code outside the braces (it must be inside)
Create a Roman numeral list in Word (automatic numbering)
This method is for list numbering (outlines, steps, headings).
It’s not the same as converting a single value like “24”.
Word can show Roman numeral lists in uppercase (I, II, III) or lowercase (i, ii, iii) depending on the style you pick.
Step-by-step (Roman numeral list in Word)
- Type your list items, with one item per line.
- Select the lines (or just place your cursor where the list starts).
- Go to Home → Numbering ▼ (the wording may vary slightly by version).
- Choose a Roman numeral numbering style (uppercase or lowercase).
Convert numbers to Roman numerals in Excel (ROMAN function)
Excel is best when you need to convert many numbers (like a whole list). Use the ROMAN() function.
Example 1: Convert one number
- Type in any cell: =ROMAN(24)
- Result: XXIV
Example 2: Convert a whole column (recommended)
- Put your normal numbers in a column (example: A1:A20).
- In the next column (example: B1), type: =ROMAN(A1)
- Press Enter.
- Fill the formula down to convert the rest of the column.
Excel limitations (important)
- Works only for 1 to 3999
- Positive numbers only
- Returns an error for 0, negative numbers, or numbers above 3999
Which method should you use?
- 1 number → Word field method (Ctrl+F9 → =Number*ROMAN → F9)
- A Roman numeral outline/list → Word numbering (Roman numeral style)
- Many numbers → Excel ROMAN() formula and fill down
Troubleshooting (quick fixes)
Word: “The braces don’t work”
- You probably typed { } manually. Delete them and use Ctrl + F9 to insert real field braces.
Word: “I pressed F9 and nothing happened”
- Click the field/result and press F9 again.
- On some laptops, you may need to hold Fn while pressing F9 (depends on your keyboard).
Excel: “ROMAN() shows an error”
- Check the number is a real number between 1 and 3999.
- Make sure it’s not 0 or negative.
Excel: “It converted the wrong cell”
- Check your reference. If your number is in A5, the formula should be =ROMAN(A5).
- When you fill down, Excel should update the row automatically.
