Let’s start

Install  pandas library

First, create a Django project, then create models

Django Export Data From Database into Excel

models.py

from django.db import models
from Django import forms 

class tbl_Employee(models.Model):    
  #  Id = models.IntegerField()
    Empcode = models.CharField(max_length=10, default='')
    firstName = models.CharField(max_length=150,null=True)
    middleName = models.CharField(max_length=100,null=True)    
    lastName = models.CharField(max_length=100,null=True)
    email = models.CharField(max_length=30,null=True)
    phoneNo = models.CharField(max_length=12, default='',null=True)
    address = models.CharField(max_length=500, default='',null=True) 
    exprience = models.CharField(max_length=50, default='',null=True)        
    DOB = models.DateField(null=True, blank=True)   
    gender = models.CharField(max_length=10, default='',null=True)
    qualification = models.CharField(max_length=50,default='',null=True)   
    
     

    def __str__(self):
        return self.firstName
                
    objects = models.Manager()

let's migrate model
python manage.py makemigrations
python manage.py migrate
 

forms.py

 
from django import forms

from crispy_forms.helper import FormHelper
from crispy_forms.layout import Layout, Div, Submit, Row, Column, Field

from .models import  tbl_Employee

class EmployeeRegistration(forms.ModelForm):
    class Meta:
        model = tbl_Employee
        fields =[ 'Empcode','firstName','middleName','lastName','email','phoneNo' ,'address','exprience',
                  'DOB','gender','qualification'
        ] 

Then let’s write a code in views.py to create a function to Export data from the database into Excel.

Views.py

from .models import tbl_Employee
import datetime as dt
import pandas as pd
import os
from django.conf import settings
from django.core.files.storage import FileSystemStorage

import csv
 
def export_users_csv(request):
   
    
    if request.method == 'POST':
        response = HttpResponse(content_type='text/csv')
        response['Content-Disposition'] = 'attachment; filename="EmployeeData.csv"'         
        writer = csv.writer(response)
        writer.writerow(['Employee Detail'])       
                
        
        writer.writerow(['Employee Code','Employee Name','Relation Name','Last Name','gender','DOB','e-mail','Contact No' ,'Address' ,'exprience','Qualification'])

        users = tbl_Employee.objects.all().values_list('Empcode','firstName' , 'middleName' , 'lastName','gender','DOB','email','phoneNo' ,'address','exprience','qualification')
        
        for user in users:
            writer.writerow(user)
        return response

    return render(request, 'exportexcel.html')

 then add the path to  the urls file

urls.py

from django.urls import path
from . import views

urlpatterns = [
    path("",views.base,name="base"),
    path("user_login/",views.user_login,name="user_login"),

 

    path('export_users_csv/', views.export_users_csv,name="export_users_csv"),  
     
    
]

Create a template folder in the root directory or app directory and a create html file named exportexcel.html

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous"> 
{% block content %}
<div class="shadow-lg continer">
<form method="post" enctype="multipart/form-data">
    {% csrf_token %}

    <div class="row">
        <div class="col-md-6 col-xs-12">
          <div class="x_panel">
            <div class="x_title">
              <h2>Data Export</h2>
           
              <div class="clearfix"></div>
            </div>
            <div class="x_content">
<div class="row">
              <div class="col-md-8 col-sm-12 col-xs-12 form-group">
                <label class="control-label col-md-3 col-sm-3 col-xs-6" for="name">Company<span class="required">*</span>
                </label>
               
              </div>
            </div>
              <button type="submit" class="btn btn-success" >Export</button>                            
                            </div>
                        </div>
                    </div>
                </div>
  </form>
  </div>
   
{% endblock %}

Then execute command 
Python manage.py runserver
