How to Zoom on Google Sheets on Android

Open Google Sheets. It's the green icon with a white table inside. It's usually in the app drawer or on the home screen.

Tap the file you want to view. Its contents will appear.

Pinch the screen with two fingers and spread them apart. Do this motion right on the part of the sheet where you'd like to zoom in. You'll now see that area larger. You can zoom in even closer by repeating this motion. To zoom back out, pinch two fingers together on the screen.
