Spire.XLS for Java provides the getStyle() method and setStyle() method under the IXLSRange interface to get or set the style of a specific cell range. To copy formatting from one cell to another, get the style first and then apply it to another cell.
import com.spire.xls.ExcelVersion;
import com.spire.xls.Workbook;
import com.spire.xls.Worksheet;
public class CopyCellFormatting {
public static void main(String[] args) {
//Create a Workbook object
Workbook workbook = new Workbook();
//Load the sample Excel file
workbook.loadFromFile("C:\\Users\\Administrator\\Desktop\\sample.xlsx");
//Get the first worksheet
Worksheet sheet = workbook.getWorksheets().get(0);
//Get the number of rows used
int rowCount = sheet.getRows().length;
//Loop through the rows
for (int i = 1; i < rowCount + 1; i++)
{
//Copy the formatting from a certain cell to another
sheet.getRange().get(String.format("C%d",i)).setStyle(sheet.getRange().get(String.format("A%d",i)).getStyle());
}
//Save the result to file
workbook.saveToFile("output/CopyFormatting.xlsx", ExcelVersion.Version2016);
}
}

Spire.XLS for Java provides you with the ability to shrink text to fit in a cell by using the setShrinkToFit method of the CellStyleObject class. The setShrinkToFit method accepts the following parameter:
boolean: specify whether to shrink text to fit in a cell.
The following example shows how to shrink text to fit in a cell in Excel using Spire.XLS for Java.
import com.spire.xls.*;
public class ShrinkTextToFitInACell {
public static void main(String []args) throws Exception {
//Create a workbook instance
Workbook workbook = new Workbook();
//Load the Excel file
workbook.loadFromFile("Sample.xlsx");
//Get the first worksheet
Worksheet sheet = workbook.getWorksheets().get(0);
//Get the cell range to shrink text
CellRange cell = sheet.getRange().get("B2:B3");
//Enable “shrink to fit”
cell.getCellStyle().setShrinkToFit(true);
//Save the file
workbook.saveToFile("ShrinkTextToFitInACell.xlsx", ExcelVersion.Version2013);
}
}
The input Excel:

The output Excel:

This article demonstrates how to change font styles (font name, font size, font color, bold, italic and underlined) of an existing PowerPoint document by using Spire.Presentation for Java.
import com.spire.presentation.*;
import com.spire.presentation.drawing.FillFormatType;
import java.awt.*;
public class ChangeFontStyles {
public static void main(String[] args) throws Exception {
//Create a Presentation object
Presentation presentation = new Presentation();
//Load the sample PowerPoint file
presentation.loadFromFile("C:\\Users\\Administrator\\Desktop\\sample.pptx");
//Get the text shape
IAutoShape shape = (IAutoShape) presentation.getSlides().get(0).getShapes().get(0);
//Get the first paragraph and change the font color of it
ParagraphEx paragraph = shape.getTextFrame().getParagraphs().get(0);
PortionEx textRange = paragraph.getFirstTextRange();
textRange.getFormat().getFill().setFillType(FillFormatType.SOLID);
textRange.getFormat().getFill().getSolidColor().setColor(Color.blue);
//Get the second paragraph and make the text bold, italic and unlined
paragraph = shape.getTextFrame().getParagraphs().get(1);
textRange = paragraph.getFirstTextRange();
textRange.getFormat().isBold(TriState.TRUE);
textRange.getFormat().isItalic(TriState.TRUE);
textRange.getFormat().setTextUnderlineType(TextUnderlineType.DASHED);
//Get the third paragraph and change the font name and size
paragraph = shape.getTextFrame().getParagraphs().get(2);
textRange = paragraph.getFirstTextRange();
textRange.getFormat().setLatinFont(new TextFont("Segoe Print"));
textRange.getFormat().setFontHeight(22f);
//Save the document
presentation.saveToFile("output/ChangeFontStyles.pptx", FileFormat.PPTX_2013);
}
}
