Search the 'net to find tools to convert CSV to YAML.
Or use Excel to read the CSV data and use this formula in a Cell:
=CONCATENATE("- Name: ", A2, CHAR(10), " GroupCode: ", "Imported", CHAR(10), " Barcode: ", C2, CHAR(10), " Portions: ", CHAR(10), " - Name: Normal", CHAR(10), " Price: ", G2)

Copy the data from the above text editor (i.e. Wordpad), and paste it into SambaPOS
Batch Create Products tool.
This is the result:
