How do I put a header on all pages in an Excel workbook?

To add a header that appears on all pages in an Excel workbook when you print it, you can use the "Page Layout" settings. Here are the steps to add a header to all pages: Open your Excel workbook that you want to add a header to. Click on the "Insert" tab in the Excel ribbon at the top of the window. In the "Text" group, you will find the "Header & Footer" button. Click on it. This will open the "Header & Footer Tools" Design tab in the Excel ribbon, and your worksheet will switch to "Page Layout View." In the "Header & Footer Elements" group, you'll see various options for adding elements to the header and footer. To add a simple text header, click on the "Header" box at the top or the "Footer" box at the bottom, depending on where you want your header. Once you click in the "Header" or "Footer" box, you can type the desired text for your header. You can also use the options in the "Header & Footer Elements" group to insert other elements like page numbers, date, time, file name, etc., into the header. Customize the header's appearance using the options in the "Header & Footer Tools" Design tab, such as font style, size, alignment, and formatting. After customizing your header, click outside the header/footer area or press the "Esc" key to exit the header/footer editing mode. You can now see your header on the first page of the worksheet in Page Layout View. To check how it will appear on other pages, you can scroll down to view other pages in this view. To exit Page Layout View and return to the normal Excel view, click the "Normal" button in the bottom right corner of the Excel window. Your header will now appear on all pages when you print the Excel workbook. To check how it will look before printing, you can use the "Print Preview" option in the "File" menu. Remember to save your workbook after making changes to preserve the header information for future use.
