Download the attached Excel sheet with load effects and open it.
Select the values of the internal forces in the table and copy them (Ctrl + C).
Then in IDEA StatiCa Connection, select the XLS Import button in the top ribbon.
With a left-click, select the first cell and paste (Ctrl + V) the values of internal forces.
Please be aware you need to have the same order of rows and columns in the Excel table as in the Load effects table in the IDEA StatiCa Connection application. If the rows or columns are switched, you will get the incorrect input of internal forces on members.
