If you’re doing a work that involves a huge amount of data, a single excel sheet can hardly meet your need. Try inserting an Excel file into another. It may enrich the information and work as a reference or an addition.
First of all, click any cell in the sheet you are editing. Choose Insert tab and click Object in Text section.
Switch to Create from File tab in Object window and hit Browse…
Find the Excel file you want and hit Insert.
Then check Display as icon and click OK to implement it.
Now the file you choose is added to the worksheet you are editing. You can double-click the icon to view the inserted Excel file.
