Hi Team,
the copy paste from excel to Board keeps only the values that are actually visualized into the Excel cell.
e.g if you copy cell showing 1.2 into Board, then it will copy 1.2 only.
But the cell may have a value like "1.22343242353452".
This is the issue when we were working with client where they see data in Millions, and even copy paste the data from excel in Millions. And this small difference creates the huge difference in Total.
Excel uses its own clipboard hence excel can copy the full numbers beyond decimals into another excel sheet.
