 The Simapro CSV files can be imported in OpenLCA in a new database like so:

 You will need to select "SimaproCSV_Import.csv" as mapping file to use.

 Finally, once imported, unlinked flows remain. They can be found under these highlighted folders:
 
 .. image:: olca_fig3.png
    :width: 500pt
    :align: center

 To link them, you need to import an additional mapping flow that you can find here
 ("Tools" > "Flow mapping" > "Open file").
 
 .. image:: olca_fig4.png
