I'm looking to insert a blank row in the second last row of a workbook anybody got the right code?
also I have a Macro that runs and opens multiple workbooks only Problem is I have to have a work book open to run the macro is there a way of having an icon on desktop to run Macro?
one last thing is there a way of creating a macro to send an email of a workbook Straight from excel?
