IEM_003: The Import of an Excel file takes a very long time


After starting the Excel Import Wizard and setting the filename, you click next or save and the cpu of the computer fires-up to 100% and nothing happens. It takes a long time (about 20 min) for the next window to appear.


In the Excel sheet you try to import, there are a lot of empty rows which Wizard tries to import. You can determine the used range by pressing Ctrl+End on keyboard.


  1. Left-click at first empty row in Excel
  2. Go to the last row and press shift+left-click and select all unused rows.
  3. Right-click and select “delete”.
  4. Save the file.
