Can Excel Spreadsheets or PowerPoint Presentations be put as files on a web site?
Some Federal agency’s internal testing has determined that the free viewer programs for these types of files may not meet all of the Section 508 software criteria. Therefore, files of these types deployed via the Internet should be converted to HTML, and then reviewed to ensure their compliance with the 508 standards for Web-based Internet and Intranet documents. If placing Excel or PowerPoint (.ppt or .xls files) documents on an INTRANET site in original form is absolutely necessary – for example a group template, then it the responsibility of the author and the business unit manager to ensure that all persons needing access to the file have full working versions of the application, not just the viewers.
