Problem:
When report data is exported to excel 2007+ format , while opening it shows 1st warning message as
If we click on "Yes" then file open up and shows 2nd warning message as

Data is exported correctly for all the columns except for few number datatype and green triangle is added to each cell of those columns indicating some warning sign as
"The number in this cell is formatted as text or preceded by an apostrophe"
