Drop table SheetName doesn't delete the sheet instead it just deletes the row . If for the 1st time you have loaded 10K rows and then again executed the package by restricting the number of rows to 3K ,the excel file will still contain those 10K empty rows as it retains the sheet along with the empty spaces .

You can use script task to delete the sheet using COM obects .But for that you need to place the Excel PIA(Primary Interop Assemply) to make it visible for VSA or else create a new excel file every time the package runs

Else as suggested by Nicarus use File System Task to delete the existing file and create a new Excel file on every execution .

Use the same components and the query for Create Table using Execute SQL task and your DFT

I believe your issue is around the method in which you are using to create the file. You have two alternatives and both should fix your issue:

Solution #1:

You can create an Excel file with those predefined columns, essentially your empty output file - this would act as your 'Template File'. Your flow would then be this:

  1. File System Task - Copy template file to output or working directory (rename if necessary)
  2. OLEDB Source Task - Query your source for the data (3000)
  3. Data Conversion Task
  4. Excel Destination Task - Put data into new Excel file

Note: You already have steps 2 thru 3 complete, you just need to make sure you are connecting to the new Excel file. Also, to clarify, step 1 is outside the Control Flow Task.

This way is helpful because you always have a blank and consistently formatted Excel file to copy and work with.

Solution #2:

The other option is to use a Script Task and create the Excel file - you could also load the data into the file in this task. This requires some basic understanding of VB.NET or C#. Basically you would need to get a XLS library (like NPOI). This is more complicated, but gives you the best functionality.

I recommend you try solution #1 and see how that works for you.
