Uploaded files contain data that are stored on the IBM Cognos Analytics server in a columnar format.
Only certain types of files can be uploaded. Supported file formats include Microsoft Excel (.xlsx and .xls) spreadsheets, and text files with comma-separated, tab-separated, semi colon-separated, or pipe-separated values.
By default, you can upload data files of up to 100 MB from your local drive. If you want to upload a workbook, remember that only the first sheet in a Microsoft Excel workbook is uploaded. If you want to upload the data from multiple sheets in a workbook, you must save the sheets as separate workbooks. After you upload files, they can be used as a source to create a data module.
The uploaded files are automatically saved in My content. Later, you can copy or move them to a folder or package in Team content.
