Corrupted File Error when writing to an Excel File

I have a query running from Toad for Data Analysts 2.6.1.568. When I run it to a new file it works perfectly. A little over 403,000of data from Banner. But when I run it to an existing excel file andsend it to a specific sheet I get an error when I try to open my excelfile with the now updated data.

Thereason I have it load there, is I am using it to perform a basicDashboard on a Summary Sheet. The data from 3 files on separatespreadsheets provide the numbers for my Dashboard.

Any Help is Appreciated
