Microsoft Office, often just called Office, is a group of computer programs and online services made by Microsoft. It helps people create and manage documents, spreadsheets, presentations, and more. Bill Gates first announced it on August 1, 1988.

At first, Office was a package of three main programs: Microsoft Word (for writing), Microsoft Excel (for numbers), and Microsoft PowerPoint (for presentations). Over time, these programs gained many shared features, like a spell checker. Microsoft Office is available for computers running Microsoft Windows and macOS. There are also versions for mobile devices like Android phones and iOS (Apple) devices. You can even use a version of Office right in your web browser, called Office on the web.

Since Office 2013, Microsoft has offered Office through a subscription service called Microsoft 365. This means you pay a regular fee to use the software and get updates. This subscription model has become very popular, even more so than buying a one-time license for the software. In 2022, Microsoft started to change the name of "Microsoft Office" to "Microsoft 365" for many of its products, but they later decided to keep the "Office" name for some traditional versions.

What's Inside Microsoft Office?

Microsoft Office comes with many different programs and services to help you with school, work, and personal projects.

Office on the web is a free, simpler version of Microsoft Office that you can use in your web browser. It includes online versions of Word, Excel, and PowerPoint. You can also access Outlook.com, OneNote, and OneDrive from the same place.

These online apps can open, edit, and save common Office files. You can also open older Office files, but they will be converted to newer formats if you want to edit them online. Files with special features like macros or passwords cannot be fully used in the web apps.

Office on the web doesn't have all the advanced features of the full desktop versions. However, you can easily open a document in the desktop app if you need more tools. Office on the web works with most modern web browsers like Microsoft Edge, Firefox, Google Chrome, and Safari. You can use it for free with a Microsoft account.

Shared Features

Most versions of Microsoft Office have a similar look and feel. For example, the "Ribbon" menu, which organizes tools into tabs, was first introduced in Office 2007. This design has even influenced how other Microsoft programs, like those in Windows 7, look.

Office programs can open and edit files saved on cloud services like OneDrive, allowing you to work on your documents from anywhere.

File Types

Before Office 2007, Microsoft Office used its own special file types. This meant that if you wanted to share files, everyone needed to use Microsoft Office. In 2008, Microsoft made information about these file types available for free.

Starting with Office 2007, the main file types became "Office Open XML" files (like .docx, .xlsx, .pptx). These are more open and can be used by other office programs too. Microsoft also made tools to help older versions of Office open these new files. Office 2010 and later versions can also open and save files in the OpenDocument Format (ODF).

Microsoft also provides tools to remove hidden information, called "metadata," from Office documents. This helps protect your privacy by removing details like who created the document or when it was last saved.

Adding More Features

A cool thing about Office is that people can create "add-ins" or "plugins" to make the programs do even more. These are like small apps that you can add to Word, Excel, or PowerPoint. For example, you might find an add-in that helps you create special charts or translate text.

Developers can sell these add-ins in the Office Store. When you open a document that uses an add-in, you might be asked to download it or start a free trial. Companies can also create their own special add-ins for their employees to use.

Password Protection

Microsoft Office has a security feature that lets you protect your documents with a password. This means only people who know the password can open or change your Word, Excel, PowerPoint, or Access files. The passwords use strong encryption to keep your information safe.

Support for Office Versions

Microsoft provides support for its Office products for a certain amount of time after they are released. This support includes security updates and technical help. Older versions of Office, like Office 2000 to Office 2016, usually received ten years of support. However, newer versions like Office 2019 and Office 2021 have shorter support periods.

Where You Can Use Office

Microsoft Office works on many different devices:

  • Windows computers: This is the most common place to use Office.
  • macOS computers: Office has special versions for Apple's Mac computers.
  • Mobile devices: There are Office apps for Windows phones, Android phones and tablets, and Apple iPhones and iPads.

The Mac and Windows versions of Office have been able to share the same file types for a long time, making it easy to work on documents across different computers.

How to Get Office

You can get Microsoft Office in a few ways:

  • Buying it once: You can buy a version like "Home & Student" or "Home & Business" with a one-time payment. These versions don't get major new features, just security updates.
  • Subscription (Microsoft 365): This is the most popular way now. You pay a regular fee (monthly or yearly) for Microsoft 365. This gives you access to the Office programs on multiple devices, plus cloud storage and other online services. With a subscription, you always get the latest features and updates.

There are different Microsoft 365 plans for families, businesses, and schools. Students can often get special deals or even free access to some Office apps through school programs.

Programs and Features That Are No Longer Available

Over the years, Microsoft has stopped offering some Office programs and features. Here are a few examples:

  • Binder: Used to combine several documents into one file.
  • FrontPage: A program for creating websites.
  • InfoPath: Used for designing and filling out electronic forms.
  • Office Assistant: This was a helpful animated character, often a paperclip named "Clippy," that offered tips and help.
  • Office Picture Manager: A basic photo management program.
  • Skype for Business: An app for instant messaging and video calls in a business setting.
