I have an excel sheet that needs to be in HTML format so it can be put on a wedb page. How do I save it and set it up so it can be used by customers on the web. There are formula's to make it interactive, Check boxes etc.
Take a look at File->Save As Web Page, and check "Add Interactivity".
From Excel Help:
When you publish an interactive workbook on a Web page, the result is an HTML file that contains special components that allow browser users to interact with the workbook. For example, users can switch between sheets using a sheet selector, manipulate data and formatting, and change formulas in each sheet. The interactive components used in the HTML file cannot be opened and modified in Excel, so you should maintain a master copy of the Excel workbook from which you published so that you can make changes to it and republish the workbook if necessary.
