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

Insert a Row and a Column in Excel

Below are the steps to insert a blank row and a blank column in an Excel worksheet.

• Create a Workbook instance.
• Load a sample Excel file using Workbook.loadFromFile() method.
• Get a specified worksheet using Workbook.getWorksheets().get() method.
• Insert a row into the worksheet using Worksheet.insertRow(int rowIndex) method.
• Insert a column into the worksheet using Worksheet.insertColumn(int columnIndex) method.
• Save the result file using Workbook.saveToFile() method.

import com.spire.xls.*;

public class InsertRowandColumn {
    public static void main(String[] args) throws Exception {
        //Create a Workbook instance
        Workbook workbook = new Workbook();

        //Load a sample Excel file
        workbook.loadFromFile("Sample.xlsx");

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

        //Insert a row into the worksheet
        worksheet.insertRow(4);

        //Insert a column into the worksheet
        worksheet.insertColumn(4);

        //Save the result file
        workbook.saveToFile("InsertRowAndColumn.xlsx", ExcelVersion.Version2013);
    }
}

Insert Multiple Rows and Columns in Excel

Below are the steps to insert multiple blank rows and columns in an Excel worksheet.

• Create a Workbook instance.
• Load a sample Excel file using Workbook.loadFromFile() method.
• Get a specified worksheet using Workbook.getWorksheets().get() method.
• Insert multiple rows into the worksheet using Worksheet.insertRow((int rowIndex, int rowCount) method.
• Insert multiple columns into the worksheet using Worksheet.insertColumn(int columnIndex, int columnCount) method.
• Save the result file using Workbook.saveToFile() method.

import com.spire.xls.*;

public class InsertRowsandColumns {
    public static void main(String[] args) throws Exception {
        //Create a Workbook instance
        Workbook workbook = new Workbook();

        workbook.loadFromFile("Sample.xlsx");

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

        //Insert multiple rows into the worksheet.
        worksheet.insertRow(5, 3);

        //Insert multiple columns into the worksheet.
        worksheet.insertColumn(4, 2);
        
        //Save the result file
