Django-import-export: InvalidDimensions encountered while trying to read file:

[davemerwin]

Django==2.0.6
django-import-export==1.0.1
openpyxl==2.4.9

I've looked a bunch and can't see what is causing the issue. I download an Excel document, add some records, and then upload that same document. Here's the resource in question:

from import_export.admin import ImportExportModelAdmin
from import_export import resources

class MasterCategoryResource(resources.ModelResource):
    class Meta:
        model = MasterCategory

class MasterCategoryAdmin(ImportExportModelAdmin):
    resource_class = MasterCategoryResource

admin.site.register(MasterCategory, MasterCategoryAdmin)

Any suggestions?

By the way, I've double check that there were not empty rows or extra columns.

I found the issue! Stupid Apple Numbers. If you open an Excel doc and then export it to Excel it adds a bunch of notices to the file and messes up the schema. Really lame.

this is not actually a solution.
I am having the same issues

Hi @srugano , this issue is a bit old, can you open another one with more detail about your problem? It seems that the OP fixed his issue. Yours probably will be different.
