I have an excel sheet (Excel 2016) that receives feeds in from various sources, which update every 30 seconds. I would like the ability to view this on my ipad and for a colleague to view it at the same time (both as read only). My thinking was to have a secure web page update every ~30 seconds (for example) but I honestly have no idea where to begin with this.
I have a gmail (paid for ) account which I believe can give me a basic web service.

Apologies for the vagueness - 1st time post

Any help, pointers would be greatly appreciated.
