A GSHEET file is a spreadsheet created by Google Sheets, an online spreadsheet program included with Google Drive. It contains a URL reference to a Google Sheets spreadsheet in Google Drive. GSHEET spreadsheets store data in cells arranged in a grid of rows and columns similarly to an .XLSX file.

Google Drive is a file storage service that also provides the Docs, Sheets, and Slides programs. Drive can be downloaded and installed in Windows or macOS as a desktop client for synchronizing remote Google Drive files with the local computer. If you install the Google Drive desktop client, your GSHEET spreadsheets are accessible within a special folder named Google Drive, which is on the local hard drive. This folder is used to synchronize files with the remote Google Drive. The GSHEET file acts as a pointer to the spreadsheet stored online, which means that when you double-click the file the spreadsheet is opened in Google Drive in your default web browser.
The Google Sheets interface appears similar to Microsoft Excel with a toolbar that allows you to insert rows and columns and functions, notes, charts, and images. You can also format data as currency or percent and move decimal places or change the text font, size, and color.
NOTE: In 2018, the Google Drive desktop applications were discontinued but you can still access Google Drive online.
