Microsoft Excel lets you embed content from other applications, including PDF files. You can embed a PDF file into a cell of an Excel worksheet and then use Excel’s security features to lock the object. This allows you to take advantage of both technologies. Embedding the PDF file allows you to present a lot of information in a protected, fixed format that the Excel spreadsheet does not natively support. You can use Excel to control access to the PDF and prevent unwanted changes to your worksheet. You can also lock specified cells to protect the worksheet.
search for PDF in link for each cell. The ones that return value has the required result.
