As you create or review a worksheet, you may want to change the font style in some cells to make them stand out. For example, you can apply a different font type, font color, and font size to text, as well as make text bold. In this article, you will learn how to apply font styles to Excel cells using Spire.XLS for Java.

Apply Different Fonts to Different Cells
Spire.XLS provides the ExcelFont class which you can use to set or change the font name, color, size, and style in a cell easily. The following are the steps to apply a font style to a specific cell using Spire.XLS for Java.
- Create a Workbook object.
- Get a specific worksheet using Workbook.getWorksheets().get() method.
- Get a specific cell using Worksheet.getCellRange() method.
- Set the value of the cell using CellRange.setText() method.
- Set the font name, color, size and style of the cell value using setFontName(), setFontColor(), setFontSize(), isBlod() methods under the ExcelFont object.
- Save the workbook to an Excel file using Workbook.saveToFile() method.
- Java
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 ApplyFontToCell {
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: Comic Sans MS");
sheet.getCellRange("B1").getCellStyle().getExcelFont().setFontName("Comic Sans MS");
//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: Blue");
sheet.getCellRange("B3").getCellStyle().getExcelFont().setColor(Color.blue);
//Make text bold
sheet.getCellRange("B4").setText("Font style: Bold");
sheet.getCellRange("B4").getCellStyle().getExcelFont().isBold(true);
//Make text italic
sheet.getCellRange("B5").setText("Font style: Italic");
sheet.getCellRange("B5").getCellStyle().getExcelFont().isItalic(true);
//Underline text
sheet.getCellRange("B6").setText("Font style: Underline");
sheet.getCellRange("B6").getCellStyle().getExcelFont().setUnderline(FontUnderlineType.Single);
//Strikethrough text
sheet.getCellRange("B7").setText("Font style: Strikethrough");
sheet.getCellRange("B7").getCellStyle().getExcelFont().isStrikethrough(true);
//Save the result file
workbook.saveToFile("output/ApplyFontToCell.xlsx", ExcelVersion.Version2016);
}
}
Apply Multiple Fonts to a Single Cell
Mixing different font styles can help you emphasize some specific characters in a cell. The following are the steps to apply multiple fonts in a cell using Spire.XLS for Java.
- Create a Workbook object.
- Get a specific worksheet using Workbook.getWorksheets().get() method.
- Create two ExcelFont objects using Workbook.createFont() method.
- Get a specific cell using Worksheet.getCellRange() method, and set the rich text content of the cell using CellRange.getRichText().setText() method.
- Apply the two ExcelFont objects to the rich text using RichText.setFont() method.
- Save the workbook to an Excel file using Workbook.saveToFile() method.
- Java
import com.spire.xls.*;
import java.awt.*;
public class ApplyMultipleFontsToCell {
public static void main(String[] args) {
//Create a Workbook instance
Workbook wb = new Workbook();
//Get the first worksheet
Worksheet sheet = wb.getWorksheets().get(0);
//Create one Excel font
ExcelFont font1 = wb.createFont();
font1.setFontName("Arial Black");
font1.setColor(Color.blue);
font1.setSize(13f);
font1.isBold(true);
//Create another Excel font
ExcelFont font2 = wb.createFont();
font2.setFontName("Algerian");
font2.setColor(Color.red);
font2.setSize(15f);
font2.isBold(true);
font2.isItalic(true);
//Insert text to cell B5
RichText richText = sheet.getCellRange("B5").getRichText();
richText.setText("Buy One, Get One Free");
//Apply two fonts to the text in the cell B5
richText.setFont(0, 8, font1);
richText.setFont(9, 21, font2);
//Save the document
wb.saveToFile("output/ApplyMultipleFontsToCell.xlsx", ExcelVersion.Version2016);
}
}
