Yes, there is a way to automatically insert a comma between numbers in Word. You can use the AutoCorrect feature in Word to achieve this. Here are the steps:

1. Open a new or existing document in Word.
2. Click on the "File" tab in the top left corner of the screen.
3. Click on "Options" at the bottom of the left-hand menu.
4. In the Word Options dialog box, click on "Proofing" in the left-hand menu.
5. Click on the "AutoCorrect Options" button.
6. In the AutoCorrect dialog box, click on the "AutoFormat As You Type" tab.
7. Check the box next to "Formatted text (with layout)" under the "Replace as you type" section.
8. Check the box next to "Use replacement table" under the "Replace as you type" section.
9. Click on the "OK" button to close the AutoCorrect dialog box.
10. Type a number with more than three digits, such as "12345".
11. Press the spacebar or type a non-numeric character, such as a letter or punctuation mark.
12. The number should automatically be formatted with a comma, like this: "12,345".

That's it! Now, every time you type a number with more than three digits, Word will automatically insert a comma between the thousands and hundreds places. This can save you time and make your documents look more professional.
