What version of Excel is required to use the Excel Checbkook templates?
Depending on which template you pick, Microsoft Excel version 2016 or newer is required for a Windows PC. For Mac users, Microsoft 2019 or newer is required. Google Sheets is not supported. Microsoft does offer an online (web browser) version of Excel but unfortunately, it does not support macros or Power Query. However, you can use the basic version of the checkbook register with the free online version of Excel. See this Google search link to determine what version of Excel you have.
