How do I get data from Excel to Java?

Example of reading excel file (.xls) file

1. import java.io.File;
2. import java.io.FileInputStream;
3. import java.io.IOException;
4. import org.apache.poi.hssf.usermodel.HSSFSheet;
5. import org.apache.poi.hssf.usermodel.HSSFWorkbook;
6. import org.apache.poi.ss.usermodel.Cell;
7. import org.apache.poi.ss.usermodel.FormulaEvaluator;

How to Write Data into Excel Sheet using Java?

1. Create a blank workbook. XSSFWorkbook workbook = new XSSFWorkbook();
2. Create a sheet and name it. XSSFSheet spreadsheet = workbook.createSheet(” Student Data “);
3. Create a row. Row row = sheet.
4. Add cells to the sheet.
5. Repeat Steps 3 and 4 to write the complete data.

To get a value from a specific cell in excel you can use the below code line. XSSFSheet has the method getRow(int rownum) It returns the logical row ( 0-based). If you ask for a row that is not defined you get a null. This is to say row 4 represents the fifth row on a sheet.

In order to extract data from Excel columns, you can use some combination of the VLOOKUP, MATCH, and INDEX functions. The VLOOKUP function is perhaps best equipped for data extraction, allowing you to look up and retrieve data from a specific column.

File: Workbook

1. Select Data > Get Data > From File > From Workbook.
2. In the Excel Browse dialog box, browse for or type a path to the file that you want to query.
3. Select Open.

Type = in your cell, then click the other sheet and select the cell you want, and press enter. That’ll type the function for you. Now, if you change the data in the original B3 cell in the Names sheet, the data will update everywhere you’ve referenced that cell. Need to calculate values from that cell?

1 Create a blank workbook. XSSFWorkbook workbook = new XSSFWorkbook (); 2 Create a sheet and name it. XSSFSheet spreadsheet = workbook.createSheet (” Student Data “); 3 Create a row Row row = sheet.createRow (rownum++); 4 Add cells to the sheet. 5 Repeat Steps 3 and 4 to write the complete data.

In this section, we are going to learn how we can read data from an excel file. In Java, reading excel file is not similar to read word file because of cells in excel file. JDK does not provide direct API to read or write Microsoft Excel or Word document. We have to rely on the third-party library that is Apache POI. What is Apache POI?

Importing data from Excel to database is a common task of a software program. So in this post, I will share with you a sample Java program that reads data from an Excel file and inserts that data to a MySQL database.
