Examples

class Contact(Model):
    first_name = models.CharField( max_length=50)
    last_name = models.CharField(max_length=50)
    middle_name = models.CharField(max_length=50, blank=True)
    email = models.EmailField(blank=True, null=True)
    phone = models.CharField(max_length=15)

    class Meta:
        verbose_name = 'contact'
        verbose_name_plural = 'contacts'

# serializers.py
from rest_framework.serializers import ModelSerializer
from django_excel_viewset.serializers import ExcelSerializerMixin
from .models import Contact


class ContactExcelSerializer(ExcelSerializerMixin, ModelSerializer):
    # Settings excel table
    excel_filename = "contacts"
    excel_sheetname = "contacts"
    excel_table_label = "Contacts"
    datetime_cell_format = {"num_format": "dd.mm.yyyy h:mm;@", "border": 1, "border_color": "#000000"}
    date_cell_format = {"num_format": "dd.mm.yyyy", "border": 1, "border_color": "#000000"}
    percent_cell_format = {"num_format": "0.00"%"", "border": 1, "border_color": "#000000"}
    format_cell_border = {"border": 1, "border_color": "#000000", "text_wrap": True}
    format_header_table = {"bold": True, "align": "center", "border": 1, "border_color": "#000000", "text_wrap": True}
    table_label_format = {"italic": True, "font_size": 14}

    class Meta:
        model = Contact
        fields = (
            "id",
            "last_name",
            "first_name",
            "middle_name",
            "phone",
            "email",
        )
        extra_kwargs = {
            "last_name": {"help_text": "Last name"},
            "first_name": {"help_text": "First name"},
            "middle_name": {"help_text": "Middle name"},
