In MS Excel, rows arrange objects from left to right and are identified by row numbers. While columns, on the contrary, arrange objects from top to bottom and are identified by column headers. When processing data in Excel, sometimes you may need to insert additional columns and rows in the middle of your data table, or delete unwanted columns and rows. In this article, you will learn how to complete the below tasks programmatically using Spire.XLS for Java.
- Insert a Row and a Column in Excel
- Insert Multiple Rows and Columns in Excel
- Delete a Specific Row and Column in Excel
- Delete Multiple Rows and Columns in Excel

Replace Images in Excel in Java
To replace a picture in Excel, you can load a new picture and then pass it as a parameter to the ExcelPicture.setPicture() method. The following are the detailed steps to replace an Excel image with another one.
- Create a Workbook instance.
- Load an Excel file using Workbook.loadFromFile() method.
- Get the first worksheet using Workbook.getWorksheets().get() method.
- Get the first picture in the worksheet using Worksheet.getPictures().get() method.
- Load an image, and then pass it as a parameter to the ExcelPicture.setPicture() method to replace the original picture with the new one.

Worksheet sheet = workbook.getWorksheets().get(0);
//Get the first image in the worksheet
ExcelPicture pic = sheet.getPictures().get(0);
// Load an image
BufferedImage bufferedImage = ImageIO.read(new File("logo.png"));
// Replace the first image with the loaded one
pic.setPicture(bufferedImage);
// Save the result file
workbook.saveToFile("ReplaceImage.xlsx", ExcelVersion.Version2016);
}
}

Workbook workbook = new Workbook();
// Load an Excel file
workbook.loadFromFile("Test.xlsx");
// Get the first worksheet
Worksheet sheet = workbook.getWorksheets().get(0);
// Get all the pictures in the worksheet
PicturesCollection pic = sheet.getPictures();
// Iterate through each image
for (int i = pic.getCount() - 1; i >= 0; i--)
{
// Get a specified image
ExcelPicture excelPic = pic.get(i);
BufferedImage loImage = excelPic.getPicture();
// Save the image to a specified file path
File file = new File(String.format("ExtractImages\\Image-%d.png", i));
