This fast and widely compatible nature should not be mistaken for Google Sheets being less powerful than its competitors on the list. In fact, the ability to download and use plugins from the Chrome Web Store makes this potentially more feature-rich and customizable than other offerings.
All you need to get started with Google Sheets is a free Google account and internet access to download the app from the Play Store. Sheets is best known for how easily you can switch between devices without having to manually save your work. You can edit offline with Google Sheets, and your spreadsheets will automatically update when your phone has internet access again.
It has deep integration with other Google products, including Gmail, Google Drive, Google Meet, and the companion office app, Google Docs. There are official Google Sheets templates that you can choose from before creating a new spreadsheet, or simply import ones you find online. All the magic of conditional formatting can be found in Google Sheets, making it fully viable for professional office use.
