Cost databases in CSV format can be imported from the "Import CSV" option in the "Import/Export" group of the toolbar of the cost database and project database management panel.

The CSV file must contain the columns with the information for the "Code", "Type", "Unit", "Summary", "Quantity" and "Price" fields. The index of each column can be specified from the file import configuration panel. Users can also specify the character set, the index of the first line of text to be imported and the field separator.

Just as with the FIEBDC-3 format files, Open BIM Quantities allows users to choose whether to remove the previous data from the cost database before importing it or updating it.
