Everything is editable to fit your situation and stays on your device.Terms, Compatibility, Refunds & Legal DisclaimersThe workbook opens in Microsoft Excel (Windows or Mac), Excel for the web, the Excel mobile apps, Google Sheets (in any modern browser, on any operating system — including Chromebook and Linux), and other apps that read .xlsx files. The free web calculator runs in a current version of Chrome, Edge, Safari, or Firefox. It's designed for a desktop or laptop; phones and small tablets can open the files but aren't the intended screen size. You'll need your own valid Microsoft Excel license or a free Google account. We don't control the changes Microsoft, Google, or Apple make to their apps, browsers, or operating systems over time, and those changes can affect how the files behave — so the 7-day refund below is your safety net.Refunds.
