How to Change Default Proofing Language in Microsoft Office

In today’s global and multicultural economy, we often find users who want to work in other languages. In this article, we show you how to use Microsoft Word, PowerPoint or other Office applications in the language(s) in which you want to work.

It is a good idea to check the options available in Office directly before you start installing new language packages for the application.

To do this, click on File > Options and select the language from the side menu. Note that the changes you make here apply to all Office applications, not just those in which you have opened the language settings.

There are two main language configuration options on this page. You can change the editing languages (including proofing) or the display language.

It is quite easy to add another editing language to Office. All you have to do is select one of the available languages from the Add Additional Editing Language menu and click the Add button to add it.

The languages available depend on the language version of Office and any other language packs, language interface packs or ScreenTip languages installed on your computer. If the correction tools, displays or help languages you want are not available, you may need to purchase and install a language pack or language interface pack.

In Office, the language options are located in the Set Office Language Settings dialog box. The display and help languages can be set independently. For example, you can set everything according to the language of your operating system or use a combination of languages for your operating system, editing, display and help.
