Viewer for Microsoft Excel XLST files
This hack allows uploaded Excel files on the Wiki or in tickets to be viewed in the web browser as a HTML table. It allows everybody to easily view the files without downloading and saving the Excel files and without even requiring Microsoft Excel. It is derived from the ExcelViewerPlugin hack, but depends upon the openpyxl library.
If you have any issues, create a new ticket.
Download the zipped source from here.
First install the openpyxl library: easy_install xlrd.
General instructions on installing Trac plugins can be found on the TracPlugins page.
After installing add the following to the mime_map property in your trac.ini file to tell Trac which types of file work with the plugin:
Upload an Excel document from an up-to-date version of Microsoft Excel as an attachment. As long as it is in the new xlst format the plugin will work. For older files use ExcelViewerPlugin. If it doesn't work confirm xlrd is installed correctly by running python and entering "import xlrd". You should see no error. Also ensure that mime_map is set properly as documented above.
