1) Click the RoboForm icon in your browser >> in the drop down click the down arrow next to the RoboForm icon.
2) Select "Preferences."
3) Select "Data & Sync."
4) Select NIS from the import dialog on the left >> choose the RoboForm folder you'd like to import the data into >> click the blue "Import from file" button.
5) Locate the .csv file containing your exported NIS data >> click the "Choose file for import" button.
6) When the import has been successfully completed, the following screen will display.
