Post Install Tip
After you successfully install the MagicSheet add-on, you can verify if it's working by trying it in a Google Spreadsheet.
Follow these steps:
Open a new spreadsheet
Enter this in any of the cell (we recommended just use A1 cell to make it easier): =MagicSheet("Sum all values in Column C")
You should notice that the SpreadSheet will auto-complete the magicsheet function once you almost type the full name
Enter wait for it to load (should be less than 1 second)
See the returned formula ("=SUM(C:C)")
