Yes, you can lock the formatting in Microsoft Word. When you apply a specific format to text, such as font or color, you don't have to worry about it being changed incorrectly. You can lock text formatting in Word so that no one can make changes to the formatting.
To do this, select the text you want to format, then go to the Home tab, which should be open by default. Click the arrow next to the font and styles panel to open up more options. Select the dropdown menu next to the Change Styles button, then select the option entitled "Protect".
Now, Word will ask you to enter a password. Enter your password twice, and then click OK. You will now have locked the formatting. When other people try to change the text formatting, a dialog box will open to ask for the password. When they enter the correct password, they will be allowed to make changes.
If you ever want to unlock the formatting, simply go to the same menu, and select the option to unprotect.
