If you've used Excel for years, switching to a web app may sound scary. Most importantly, though, Excel Online now lets you connect your spreadsheet with other web apps to gather data and start automated workflows-and since it syncs with traditional Microsoft Excel, you can use the Online version to add automations to any spreadsheet. Similar to Google Sheets, Microsoft Excel Online lets you collaborate with others in real-time, gather answers in an online survey, and crunch numbers with Excel functions. Microsoft Excel Online is a free, online version of Excel that includes the functions, chart tools, and more that you'd expect from a spreadsheet. That latter version is perhaps the most interesting. Today, you can use Excel on Windows, Mac, iOS, Android, and even the web. It's not just a desktop app anymore, either. Decades after its introduction on the original Macintosh, Excel continues to be the most powerful spreadsheet app. Excel is synonymous with spreadsheets, and for good reason.
