Google Sheets

Google Sheets is a spreadsheet program included as part of the free, web-based Google Docs Editors suite offered by Google. The service also includes: Google Docs, Google Slides, Google Drawings, Google Forms, Google Sites and Google Keep. Google Sheets is available as a web application, mobile app for: Android, iOS, Microsoft Windows, BlackBerry OS and as a desktop application on Google's ChromeOS. The app is compatible with Microsoft Excel file formats. The app allows users to create and edit files online while collaborating with other users in real-time. Edits are tracked by a user with a revision history presenting changes. An editor's position is highlighted with an editor-specific color and cursor and a permissions system regulates what users can do. Updates have introduced features using machine learning, including "Explore", offering answers based on natural language questions in a spreadsheet.

History
Google Sheets originated from XL2Web, a web-based spreadsheet application developed by 2Web Technologies, founded by Jonathan Rochelle and Farzad “Fuzzy” Khosrowshahi. XL2Web was acquired by Google in 2006 and turned into Google Labs Spreadsheets. It was launched as a test for a limited number of users, on a first-come, first-served basis on June 6, 2006. The limited test was later replaced with a beta version available to all Google Account holders, around the same time as an official announcement press release was issued. In March 2010, Google acquired the online document collaboration company DocVerse. DocVerse allowed multiple-user online collaboration on Excel-compatible documents as well as other Microsoft Office formats such as Microsoft Word and Microsoft PowerPoint. Improvements based on DocVerse were announced and deployed in April 2010. In June 2012, Google acquired Quickoffice, a freeware proprietary productivity suite for mobile devices. In October 2012, Google Spreadsheets was renamed Google Sheets and a Google Chrome app was released that provided shortcuts to Sheets on Chrome's new tab page.
