I searched the forum and came upon the following instructions on how to do this.
To loop through Excel tables by using the Foreach ADO.NET Schema Rowset enumerator
1. Create an ADO.NET connection manager that uses the Microsoft Jet OLE DB Provider to connect to an Excel workbook. On the All page of the Connection Manager dialog box, make sure that you enter Excel 8.0 as the value of the Extended Properties property.
2. Create a string variable that will receive the name of the current table on each iteration of the loop.
3. Add a Foreach Loop container to the Control Flow tab. For information on configuring the ForeachLoop, see How to: Configure a Foreach Loop Container.
4. On the Collection page of the Foreach Loop Editor, select the Foreach ADO.NET Schema Rowset enumerator.
5. As the value of Connection, select the ADO.NET connection manager that you created previously.
6. As the value of Schema, select Tables.
Note The list of tables in an Excel workbook includes both worksheets (which have the $ suffix) and named ranges. If you have to filter the list for only worksheets or only named ranges, you may have to write custom code in a Script task for this purpose. For more information, see Working with Excel Files with the Script Taskb8fa110a-2c9c-4f5a-8fe1-305555640e44.
7. On the Variable Mappings page, map Index 2 to the string variable created earlier to hold the name of the current table.
8. Close the Foreach Loop Editor.
9. Create tasks within the Foreach Loop container that use the Excel connection manager to perform the same operations on each Excel table in the specified workbook.
I read thru the instruction, and although I haven't implemented it yet, I have a general idea of how this is going to work. The question I have is with step 2. It suggests that I create a variable to hold the tab names so that the loop knows which tab it needs to read on a particular interation. But, how do I know what the tab names are going to be?
In my case, I need to read one Excel file that has a lot of tabs (the number of tabs can vary on the day I read the file) and go thru each one. Each tab represents an account name and I do not know what accounts will be contained in a particular day's file. Each tab has the same data structure.
