Share data in real time

I have a spreadsheet we use to create 'match cards' at a tournament. There is a data file which occasionally needs to be changed during the tournament. We are looking to see if it would be possible to edit that data on a different computer while the spreadsheet is in use. Attached is the match card spreadsheet. We tried to 'share' the workbook but that was not allowed because it uses a Macro for printing. Is there a different solution? I am willing to move the data to a seperate place if that makes it easier.

you can use Excel webapp where multiple people can edit at the same time. You may not use macro in it but you can still print it using the 'backend' computer.
