If you would like to manually upload several products into PULPO WMS you can use the CSV upload feature.
The CSV Template can be found in the Products section of the Web Application.
In this excel file, you can find additional product csv import guides.
The CSV file editing and uploading can be challenging since excel and other programs tend to change the formats automatically. The UTF-8 option (Save as UTF-8) when you save the file before uploading is important because of this.
