In the process of manipulating Excel worksheets, sometimes you may encounter the situation where the text in a cell is so long that some of it is hidden. At this time, it’s recommended to wrap the extra-long text into multiple lines so you can see it all. This article will demonstrate how to programmatically wrap or unwrap text in Excel cells 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.

Wrap or Unwrap Text in Excel cells
Spire.XLS for Java supports wrapping or unwrapping text in Excel cells using the setWrapText() method provided by the IStyle interface. Below are detailed steps for your reference.
- Create a Workbook instance.
- Load a sample Excel document using Workbook.loadFromFile() method.
- Get a specific worksheet of the document using Workbook.getWorksheets().get() method.
- Get a specific cell of the worksheet using Worksheet.getRange().get() method.
- Get the style of the specified cell using XlsRange.getStyle() method and set whether the text is wrapped or not using setWrapText() method provided by IStyle interface.
- Save the document to another file using Workbook.saveToFile() method.
- Java
import com.spire.xls.ExcelVersion;
import com.spire.xls.Workbook;
import com.spire.xls.Worksheet;
public class WrapOrUnwrapText {
public static void main(String[] args) {
//Create a Workbook instance
Workbook workbook = new Workbook();
//Load a sample Excel document
workbook.loadFromFile("C:\\Users\\Test1\\Desktop\\sample.xlsx");
//Get the first worksheet
Worksheet sheet = workbook.getWorksheets().get(0);
//Wrap text in the cell "D8"
sheet.getRange().get("D8").getStyle().setWrapText(true);
//Unwrap text in the cell "D6"
sheet.getRange().get("D6").getStyle().setWrapText(false);
//Save the document to another file
workbook.saveToFile("output/WrapOrUnwrapText.xlsx", ExcelVersion.Version2013);
}
}
