Hi Deepak,
In Reporting Services, we can only display one type of data in one column. Since the column with a string type, it inherit the properties of that textbox which comes from the source data when the report export to excel. This is by design.
While in Excel level, we can unchecked "Enable background error checking" option to avoid this issue. Click File->Options-Formulas, then unchecked "Enable background error checking" option under Error Checking group. Then the green triangle on the top
left hand corner will disappear.

Hope this helps.
