Hi there! Unfortunately, section breaks are not a feature in Microsoft Excel like they are in Microsoft Word. However, there is a workaround that you can use to achieve the same result.

To have different headers for different pages, you can use the Page Setup feature in Excel. Here's how:

1. Click on the Page Layout tab in the ribbon at the top of the Excel window.
2. Click on the small arrow in the bottom right corner of the Page Setup group to open the Page Setup dialog box.
3. In the Page Setup dialog box, click on the Header/Footer tab.
4. In the Header/Footer tab, you can customize the header and footer for your worksheet. You can use the buttons on the left side of the dialog box to insert different elements into your header or footer, such as page numbers, the date, or the file name.
5. To have different headers for different pages, click on the "Different first page" checkbox. This will allow you to have a different header on the first page of your worksheet.
6. You can also click on the "Different odd and even pages" checkbox to have different headers on odd and even pages of your worksheet.
