While on client site recently a query was raised regarding using the AutoSum function in Excel for the exported Resource Availability view, this didn’t work due to the hours containing an h.

Export to Excel:
As you can see the hours contain the digits as well as h, to remove h just use find and replace, typing h in the find what field and leave the replace with field empty. Firstly select the dataset / range as below:

Click Replace All and the h will be removed:
Any calculations will now work including AutoSum:
