Add pictures or texts in your worksheets to mark it as confidential or show it as a draft version. Microsoft Excel does not support in-built watermarks feature yet so the process of adding watermark in excel sheets is different.
Step 1: Open your Excel sheet.
Step 2: Click on the Insert option from the ribbon bar > Header and Footer.
Step 3: Select the Watermark which you want to insert in the sheet.
Step 4: The selected Watermark will add in the sheet.
Step 5: We also can drag and drop the watermark from one page to other page.
