Yes, there is a way to make multiple copies of a sheet in a new workbook in Excel 2003. Here are the steps:

1. Open the workbook that contains the sheet you want to copy.
2. Right-click on the sheet tab and select "Move or Copy" from the menu.
3. In the "Move or Copy" dialog box, select "New Workbook" from the "To book" dropdown menu.
4. Check the "Create a copy" checkbox.
5. In the "Before sheet" dropdown menu, select "(move to end)".
6. Click "OK".

This will create a new workbook with a copy of the sheet you selected. To make 29 copies of the sheet, simply repeat these steps 28 more times.

Alternatively, you can use a macro to automate this process. Here's an example macro that will create 29 copies of the active sheet in a new workbook:

1. Press Alt + F11 to open the Visual Basic Editor.
2. Click on "Insert" in the menu bar and select "Module".
3. Paste the following code into the module:

4. Press F5 to run the macro.

This will create 29 copies of the active sheet in separate workbooks, each named "Copy 1.xls", "Copy 2.xls", etc. You can modify the macro to suit your needs, such as changing the number of copies or the naming convention.
