Software & Apps MS Office How to Turn On/Off Excel's AutoComplete Feature How to control AutoComplete in Excel Share Pin Email Print MS Office Excel Word Powerpoint Outlook By Ted French Writer Former Lifewire writer Ted French is a Microsoft Certified Professional who teaches and writes about spreadsheets and spreadsheet programs. our editorial process Ted French Updated November 13, 2019 The AutoComplete option in Microsoft Excel will automatically fill in data as you type, but it isn't useful in every circumstance. Fortunately, you can disable or enable AutoComplete whenever you like. When You Should and Shouldn't Use AutoComplete This feature is helpful when entering data into a worksheet that contains lots of duplicates. With AutoComplete on, when you start typing, it will auto-fill the rest of the information from the context around it, to speed up data entry. Say you're entering the same name, address, or other information into multiple cells. Without AutoComplete, you'd have to retype the data or copy and paste it over and over, which wastes time. For example, if you typed "Mary Washington" in the first cell and then many other things in the following ones, like "George" and "Harry," you can type "Mary Washington" again a lot faster by just typing "M" and then pressing Enter so that Excel will auto-type the full name. You can do this with any number of text entries in any cell in any series, meaning that you could then type "H" at the bottom to have Excel suggest "Harry," and then type "M" again if you need to have that name auto-completed. There's no need to copy or paste any data. However, AutoComplete isn't always your friend. If you don't need to duplicate anything, it will still auto-suggest it each time you start typing something that shares the same first letter as the previous data, which can often be more of a bother than a help. Enable/Disable AutoComplete in Excel The steps for enabling or disabling AutoComplete in Microsoft Excel are different depending on the version you're using: In Excel 2019, 2016, 2013, and 2010 Navigate to the File > Options menu.
