ODS (OpenDocument Spreadsheet) is an XML-based file format created by the Calc program. Similar to MS Excel files, ODS files store data in cells organized into rows and columns, and can contain text, mathematical functions, formatting, and more. Sometimes, you may need to convert an Excel file to an ODS file to ensure that the file can be viewed by more applications in different operating systems. This article will demonstrate how to accomplish this task programmatically using Spire.XLS for Java.

Install Spire.XLS for Java

First of all, you're required to add the Spire.Xls.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

<repositories>
    <repository>
        <id>com.e-iceblue</id>
        <name>e-iceblue</name>

        <groupId>e-iceblue</groupId>
        <artifactId>spire.xls</artifactId>
        <version>14.11.0</version>
    </dependency>
</dependencies>
    

Convert Excel to ODS

The detailed steps are as follows:

• Create a Workbook instance.
• Load a sample Excel file using Workbook.loadFromFile() method.
• Convert the Excel file to ODS using Workbook.saveToFile() method.

import com.spire.xls.*;

public class toODS {
    public static void main(String[] args) {
        //Create a Workbook instance
        Workbook workbook = new Workbook();

        //Load a sample Excel document
        workbook.loadFromFile("C:\\Files\\sample.xlsx");

        //Convert to ODS file
        workbook.saveToFile("ExcelToODS.ods", FileFormat.ODS);
    }
}
