I am in need of a module to display Excel spreadsheets and the option be viewable by all and also able to edit them on the fly with group permissions. I need to allow one of my members to manually update a spreadsheet that we currently use to track information. I know that in Excel, I can save the workbook as a webpage and also make it editable/interactive. My problem with this is, anyone can edit it. Is there a module out somewhere that I may have overlooked that can display and provide appropriate permissions for Excel & Spreadsheets??

Thanks in advance
