Using uploaded files as data module sources
Uploaded files are supported types of data files, such as Microsoft Excel (.xlsx and .xls) spreadsheets or text (.csv) files, that you can upload into Cognos® Analytics by yourself.
Files that are already uploaded to Cognos Analytics are stored in Team content or My content. You can also upload files after you start creating your data module by using the upload file facility in the Select sources dialog box.
