Automatic Extend Formatting



 


Copying - Typing at the End

Excel will automatically copy formulas when you add new data to a table if the same formula appears in four or more consecutive rows or columns.
Typing May below the table and inserting numerical data into cells "C7", "D7" and "E7" will cause the formula in column "F" to be automatically copied to cell "F7".


 


Important

If an AutoFormat has been applied to the list then the format is not automatically extended
Dates are not automatically formatted
Any data pasted from the clipboard will not have automatic formats applied to it.
