• delimiter (str, optional) – The delimiter in the CSV file. Default is “;”.

• name (str, optional) – The name of the project. If the name is not provided, it is extracted from the CSV file.

• encoding (str, optional) – The character encoding in the SimaPro CSV file. Defaults to “cp1252”.

Returns

• datasets (list) – The list of extracted datasets from the CSV file.

• global_parameters (dict) – The dictionary of global parameters for the CSV file.
