When you want to create a line break (line feed) in a cell, you press Alt + Enter, to start a new line. You can put one or more line breaks in a cell, to make the contents easier to read. But how can you find and replace line breaks in Excel?

Find Line Breaks in Excel
Line breaks are easy to add, but a little trickier to remove.
To find specific text in Excel, you can use Ctrl + F to open the Find and Replace dialog box. However, if you try to type Alt + Enter in the Find What box, you’ll just hear a beep from your computer. Excel won’t let you put that shortcut into the Find What box.
Instead of using Alt + Enter, you can use a special shortcut to enter a line break in the Find What box: Ctrl + J
Why does that work? A line break is character 10 in the ASCII character set, and the Ctrl + J shortcut is the ASCII control code for character 10.
Find and Replace a Line Break
To find a line break, and replace it with a space character, follow these steps. There is a video below, that shows the steps.
- Select the cells that you want to search
- On the keyboard, press Ctrl + H to open the Find and Replace dialog box, with the Replace tab active
- Click in the Find What box
- On the keyboard, press Ctrl + J to enter the line break character — NOTE: No text will appear in the Find What box — just a small blinking dot
- Press the Tab key on the keyboard, to move to the Replace With box
- Type a space character
- Then, click Find Next or Find All, to find the cells with line breaks.
- OR, click Replace or Replace All, to replace the line breaks with space characters.
NOTE: If these steps don’t work, try the tips and troubleshooting suggestions below.

Tips and Troubleshooting
Update: Here are a few tips and troubleshooting suggestions, to use while you find and replace line breaks in Excel. Thank you to everyone who commented, and added suggestions.
- If Ctrl + J does not work, press the Alt key, and type 0010 on the number keypad (do not use the numbers above the letters)
- If the Excel file has never been saved, try saving the file before doing this find and replace
- Try doing this find and replace when you first open Excel, before using the Find box for any other searches. Or, try the next tip — you might have extra line breaks in the Find box.
- Be sure that you aren’t inserting more than one line break in the Find box — the Find box looks empty after you type Ctrl+J, so it is easy to accidentally type in there again. To avoid this problem:
- Click on the Replace tab — you’ll see a light border around the word.
- Press the Tab key — that will select the Find What box, and anything that is entered there.
- Type Ctrl+J (that will replace anything that you previously typed in Find)

This tip doesn’t work on an unsaved document. The document should be saved and then Ctrl J works..
I could not find this in the MS Excel support info, so THANK YOU SO MUCH!!! I knew it had to exist somewhere!
Thank you for the hint, it worked!
Thanks for this,
It’s amazing how much you can learn and can forget if you haven’t used a technique after a few years.
