I have had this problem too, if you right click on the link in the email and click Save Link As, it will download.

The information is there. I used the information from the register list to get my BMV information in to HA.
In my setup, the BMV has VRM instance 289 which corresponds to UnitID 238 from the unit ID mapping tab of the spreadsheet.
Then the registers will be in the range of the "com.victronenergy.battery" from the field list tab. For instance, register 259 is battery Voltage, scale factor is 100.

In HA configuration, I have a separate modbus.yaml file to put the modbus "sensors".
Something like this:
