2# Sample Code

import com.spire.xls.ExcelVersion;
import com.spire.xls.FontUnderlineType;
import com.spire.xls.Workbook;
import com.spire.xls.Worksheet;

import java.awt.*;

public class SetFontStyle
{
    public static void main(String[] args) {

        //Create a workbook
        Workbook workbook = new Workbook();

        //Get the first sheet
        Worksheet sheet = workbook.getWorksheets().get(0);

        //Set font name
        sheet.getCellRange("B1").setText("Font name: Time New Roman");
        sheet.getCellRange("B1").getCellStyle().getExcelFont().setFontName("Time new Roman");

        //Set font size
        sheet.getCellRange("B2").setText("Font size: 20");
        sheet.getCellRange("B2").getCellStyle().getExcelFont().setSize(20);

        //Set font color
        sheet.getCellRange("B3").setText("Font color: Red");
        sheet.getCellRange("B3").getCellStyle().getExcelFont().setColor(Color.red);

        //Set to bold
        sheet.getCellRange("B4").setText("Font style: Bold");
        sheet.getCellRange("B4").getCellStyle().getExcelFont().isBold(true);

        //Set to underline
        sheet.getCellRange("B5").setText("Underline: Single");
        sheet.getCellRange("B5").getCellStyle().getExcelFont().setUnderline(FontUnderlineType.Single);
        sheet.getCellRange("B6").setText("Underline: Double");
        sheet.getCellRange("B6").getCellStyle().getExcelFont().setUnderline(FontUnderlineType.Double);

        //Set to italic
        sheet.getCellRange("B7").setText("Font style: Italic");
        sheet.getCellRange("B7").getCellStyle().getExcelFont().isItalic(true);

        //Save the result file
        workbook.saveToFile("FontStyles.xlsx", ExcelVersion.Version2016);
    }
