The PDF File has been inserted into an Excel sheet as an object similar to a chart or any shape. We can drag it or resize it as we want. Repeat the same steps to insert more PDF files into the sheet.

You can insert PDFs into Excel as an object, data connection, or hyperlink. If you are unable to import a PDF or file in Excel, it might be the case that the Excel worksheet or workbook is locked.

To have Excel insert the PDF, first open the spreadsheet in Excel. Then, click the "Insert" tab on the ribbon menu and click the "Object" icon within the "Text" group of command icons.
