To do what you want requires a shared work/collaboration space such as SharePoint. It should be easier just to merge the Excel files from each user into a new file. There are many options to choose from when merging. You might be able to do this over bluetooth if WiFi isn't permitted. Otherwise, copy them all to a USB device and merge there. Macros should not matter using this process. There's lots of info on the web.
