In Excel, there is no function that would be an alternative to IMPORTRANGE in Google Sheets. However, Excel allows you to link a data range between two worksheets or workbooks in another way. For this, you need to select a range of cells in the source workbook and copy them. Then open the destination Excel file, right-click on a cell where you want to insert the range, and select Paste Link. Now, if you change values in the source range, those changes will be visible in the destination range as well.
