I cannot upload an XLS File
First make sure you are uploading to the right area (i.e. if it's a product upload, make sure 'product' is selected from the drop-down menu in and upload is also selected. If it's a large file, you could cut the excel file into pieces and upload them that way. So for example, the file is 10mb XLS, you could make it 3.3MB and upload 3 times (adding additional data with each upload). Be careful to make sure the last one is processed before adding the next spreadsheet.
