Upload file (csv, xlsx) do'esn't work

Hello, I have a problem with importing csv and excel files into my django database made with PyCharm. 
I use the import_export package. 
When importing my csv file, I can only find the names of the Name column but the values under the different columns (which are numbers) are not imported. 
How can I solve this problem? 
Thanks in advance

Unfortunately, it's not possible to tell what's wrong without a project sample with table scheme, code sample with data import and csv example. If possible, please provide a sample, you can upload it here: https://uploads.services.jetbrains.com/ and tell us the upload ID.
Quite common advice is to make sure that the data type of the columns in your csv file is compatible with the data type of the corresponding fields in your Django model.
