Import Data From Excel To DB Using AngularJS And Web API 2

Introduction

In this article, we will explain how to import data from an Excel sheet to SQL Server database by using library named js-xlsx. In this demo, we are going to create a basic Application whose role is to show you the steps, which are used to achieve our goal. Prior to it, you need to have some basic knowledge on AngularJS, Web API2 and Entity Framework ORM. I hope, you will like my article.

In this article, we are going to

  • Create database.
  • Create Web API Application.
  • Configuring Entity Framework ORM.
  • Create controller.
  • AngularJS part.
  • Create HTML page.

Let’s start.

SQL database part

Here, you will find the scripts to create a database and table.

Create a database

  110. GO   

Create a table 

  1. USE [DbEmployee]  
  2. GO  
  3.   
  4. /****** Object:  Table [dbo].[EmployeeTable]    Script Date: 3/25/2017 8:23:51 AM ******/  
  5. SET ANSI_NULLS ON  
  6. GO

  8. SET QUOTED_IDENTIFIER ON  
  9. GO  
  10.   
  11. SET ANSI_PADDING ON  
  12. GO  
  13.   
  14. CREATE TABLE [dbo].[EmployeeTable](  
  15.     [EmployeeID] [int] IDENTITY(1,1) NOT NULL,  
  16.     [FirstName] [varchar](50) NULL,  
  17.     [LastName] [varchar](50) NULL,  
  18.     [Gender] [varchar](50) NULL,  
  19.     [Designation] [nchar](10) NULL,  
  20.     [Salary] [int] NULL,  
  21.     [City] [varchar](50) NULL,  
  22.     [Country] [varchar](50) NULL,  
  23.  CONSTRAINT [PK_EmployeeTable] PRIMARY KEY CLUSTERED   
  24. (  
  25.     [EmployeeID] ASC  
  26. )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]  
  27. ) ON [PRIMARY]  
  28.   
  29. GO  
  30.   
  31. SET ANSI_PADDING OFF  
  32. GO   

After creating the table, you can add some records. as shown below.

AngularJS

 Create your Web API Application

Open Visual Studio and select File >> New Project.

The "New Project" Window will pop up. Select ASP.NET Web Application (.NET Framework), name your project and click OK.

AngularJS

Now, new dialog will pop up to select the template. We are going to choose Web API template and click OK button.

AngularJS

After creating our project, we are going to add ADO.NET Entity Data Model.

Adding ADO.NET Entity Data Model

To add ADO.NET Entity Framework, right click on the project name, click Add > Add New Item. A dialog box will pop up. Inside Visual C#, select Data followed by ADO.NET Entity Data Model and enter the name for your Dbcontext model as DbEmployee. Finally click Add.

AngularJS

In this level, we are going to choose EF Designer from the database, as show below.

AngularJS

After clicking Next button, a dialog will pop up with the name connection properties. You need to enter your Server name and connect to a database panel, select database via dropdown List (DbEmployee). Now, click OK button.

AngularJS

Now, the dialog Entity Data Model Wizard will pop up for choosing an object, which we need to use. In our case, we are going to choose EmployeeTable and click Finish button. Finally we see that EDMX model generates EmployeeTable class.

AngularJS

Create a controller

Now, we are going to create a controller. Right click on the controllers folder > Add > Controller> select Web API 2 Controller – Empty > click Add.

AngularJS

Enter Controller name (‘EmployeeController’).

AngularJS

EmployeeController.cs 

  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Net;  
  5. using System.Net.Http;  
  6. using System.Web.Http;  
  7. using System.Web.Http.Description;  
  8.   
  9. namespace ExcelToDB.Controllers  
  10. {  
  11.     [RoutePrefix("api/Employee")]  
  12.     public class EmployeeController : ApiController  
  13.     {  
  14.         //DbContext  
  15.         DbEmployeeEntities db = new DbEmployeeEntities();  
  16.   
  17.   
  18.         [Route("Save")]  
  19.         [HttpPost]  
  20.         [ResponseType(typeof(void))]  
  21.         public IHttpActionResult Save(List<EmployeeTable> employeeList)  
  22.         {  
  23.             if (!ModelState.IsValid)  
  24.             {  
  25.                 return BadRequest(ModelState);  
  26.             }  
  27.   
  28.             foreach(var data in employeeList)  
  29.             {  
  30.                 db.EmployeeTables.Add(data);  
  31.             }  
  32.             db.SaveChanges();  
  33.   
  34.             return StatusCode(HttpStatusCode.OK);  
  35.   
  36.         }  
  37.   
  38.     }  
  39. }   

As you can see, I am creating Save() action, which takes an employee list as a parameter. We will now save the data to an employee table.

AngularJS part

In order to create new js file, right click on Scripts folder > Add > JavaScript file.

AngularJS

  34.   
  35.                 var dataObjects = XLSX.utils.sheet_to_json(workbook.Sheets[first_sheet_name]);  
  36.   
  37.                 //console.log(excelData);  
  38.   
  39.                 if (dataObjects.length > 0) {

  63.             method: "POST",  
  64.             url: "api/Employee/Save",  
  65.             data: JSON.stringify(data),  
  66.             headers: {  
  67.                 'Content-Type': 'application/json'  
  68.             }  
  69.   
  70.         }).then(function (data) {  
  71.             if (data.status) {  
  72.                 $scope.msg = "Data has been inserted ! ";  
  73.             }  
  74.             else {

  79.         })  
  80.
