A few of the users here at Quay Australia have asked me about how to send out links to spreadsheets saved to Box that will open the workbook in question to a particular worksheet and cell, like the capability in One Drive detailed here: https://superuser.com/questions/804139/can-i-modify-excel-online-share-urls-to-open-to-a-specific-worksheet. I've tried this method with a Box link and it just opens the file where the last editor left off. If you could develop this capability, many of my end-users at Quay Australia would be very thankful.
