Creating XLSB Files in Java

Creating XLSB Files in Java: A Step-by-Step Guide with Code Examples

Introduction:

XLSB (Excel Binary Workbook) files are a binary format used by Microsoft Excel to store workbook data. In Java, you can generate XLSB files using the Apache POI library, which provides comprehensive support for working with Microsoft Office formats. In this blog post, we'll explore how to create XLSB files in Java using Apache POI with code examples.

Step 1: Set up your Java project:

Before you begin, make sure to set up a Java project and include the Apache POI library in your classpath. You can download the latest version of Apache POI from the official Apache POI website or use a build tool like Maven or Gradle to manage your project dependencies.

// Maven Dependency
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>5.0.0</version>
</dependency>

Step 2: Write Java code to generate XLSB file:

Now, let's create a simple Java program that generates a basic XLSB file with a sheet containing some data.

import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.streaming.SXSSFWorkbook;

import java.io.FileOutputStream;
import java.io.IOException;

public class XLSBGenerator {

public static void main(String[] args) {
// Create a new workbook
try (Workbook workbook = new SXSSFWorkbook()) {
// Create a sheet in the workbook
Sheet sheet = workbook.createSheet("Sheet1");

// Create a header row
Row headerRow = sheet.createRow(0);
Cell headerCell = headerRow.createCell(0);
headerCell.setCellValue("Name");

// Create data rows
String[] names = {"John Doe", "Jane Smith", "Bob Johnson"};
for (int i = 0; i < names.length; i++) {
Row dataRow = sheet.createRow(i + 1);
Cell dataCell = dataRow.createCell(0);
dataCell.setCellValue(names[i]);
}

// Save the workbook to a file
try (FileOutputStream fileOut = new FileOutputStream("example.xlsb")) {
workbook.write(fileOut);
System.out.println("XLSB file generated successfully!");
} catch (IOException e) {
e.printStackTrace();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}

This code creates a simple XLSB workbook with a sheet named "Sheet1" and populates it with a header row and some data rows.

Conclusion:

Generating XLSB files in Java can be achieved easily using the Apache POI library. In this blog post, we've walked through the process of setting up a Java project, including the necessary dependencies, and provided a code example to create a basic XLSB file. Feel free to customize the code according to your specific requirements, and happy coding!
