AutoFit Column Width and Row Height in Excel
The detailed steps are as follows.
- Create a Workbook object.
- Load a sample Excel document using Workbook.loadFromFile() method.
- Get a specified worksheet using Workbook.getWorksheets().get() method.
- Get the used range on the specified worksheet using Worksheet.getAllocatedRange() method.
- Autofit column width and row height in the range using CellRange.autoFitColumns() and CellRange.autoFitRows() methods.
- Save the document to another file using Workbook.saveToFile() method.
- Java
import com.spire.xls.*;
public class AutoFitColumn {
public static void main(String[] args) {
//Create a Workbook object
Workbook workbook = new Workbook();
//Load a sample Excel document
workbook.loadFromFile("E:\\Files\\Test.xlsx");
//Get the first worksheet
Worksheet worksheet = workbook.getWorksheets().get(0);
//AutoFit column width and row height
worksheet.getAllocatedRange().autoFitColumns();
worksheet.getAllocatedRange().autoFitRows();
//Save the document
workbook.saveToFile("AutoFitCell.xlsx", ExcelVersion.Version2013);
}
