JDBC Connection to Microsoft Excel

Introduction

 
In this article, we will describe how a Java program connects to a Microsoft Excel sheet and retrieves the data from the sheet. And this connection is made with the JdbcOdbc bridge driver API provided by the SQL package in Java. You have to perform some steps to make the connection with an Excel sheet.
 
Step 1: First create the workbook (Excel sheet); if your Excel sheet is already created then there is no need to create it again.

Step 2: To start, we need to setup the local ODBC connection. So select Administrative Tools in Control Panel.

Step 3: Select Data Source (ODBC) option.

Step 7: Give the data source name and select your workbook.

So now your DSN is created.
 
Java code
  1. import java.sql.*;  
  2. public class ExcelConnection  
  3. {  
  4.     public static void main(String[] args)  
  5.     {  
  6.         try  
  7.         {  
  8.             Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");  
  9.             Connection con = DriverManager.getConnection("jdbc:odbc:abhishek");  
  10.             Statement st = con.createStatement();  
  11.             ResultSet rs = st.executeQuery("Select * from [Sheet1$]");  
  12.             ResultSetMetaData rsmd = rs.getMetaData();  
  13.             int numberOfColumns = rsmd.getColumnCount();  
  14.             while (rs.next())  
  15.             {  
  16.                 for (int i = 1; i <= numberOfColumns; i++)  
  17.                 {  
  18.                     if (i > 1)  
  19.                         System.out.print(", ");  
  20.                     String columnValue = rs.getString(i);  
  21.                     System.out.print(columnValue);  
  22.                 }  
  23.                 System.out.println("");  
  24.             }  
  25.             st.close();  
  26.             con.close();  
  27.         } catch (Exception ex) {  
  28.             System.err.print("Exception: ");  
  29.             System.err.println(ex.getMessage());  
  30.         }  
  31.     }  
  32. }
