Split Workbook or Worksheet into Multiple Excel Documents in Java

When you have a large Excel document to deal with, you may want to split the workbook into multiple workbooks, each containing one worksheet. If the worksheet has a lot of data and the data areas can be easily classified or distinguished, you can also split the worksheet into several Excel documents according to the data areas.

In this article, you’ll learn how to split a workbook or a worksheet by using Free Spire.XLS for Java.

Install Spire.Xls.jar

If you create a Maven project, you can easily import the jar in your application using the following configurations. For non-Maven projects, download the jar file from this link and add it as a dependency in your application.

Example 1. Split one worksheet into multiple Excel documents

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

public class SplitWorksheet {

    public static void main(String[] args) {

        //Create a Workbook object to load the original Excel document
        Workbook bookOriginal = new Workbook();
        bookOriginal.loadFromFile("C:\\Users\\Administrator\\Desktop\\Emplyees.xlsx");

        //Get the fisrt worksheet
        Worksheet sheet = bookOriginal.getWorksheets().get(0);

        //Get the header row
        CellRange headRow = sheet.getCellRange(1, 1, 1, 5);

        //Get two cell ranges
        CellRange range1 = sheet.getCellRange(2, 1, 6, 5);
        CellRange range2 = sheet.getCellRange(7, 1, 11, 5);

        //Create a new workbook
        Workbook newBook1 = new Workbook();

        //Copy the header row and range 1 to the new workbook
        sheet.copy(headRow, newBook1.getWorksheets().get(0), 1, 1, true, false);
        sheet.copy(range1, newBook1.getWorksheets().get(0), 2, 1, true, false);

        //Copy the column width from the original workbook to the new workbook
        for (int i = 0; i < sheet.getLastColumn(); i++) {

            newBook1.getWorksheets().get(0).setColumnWidth(i + 1, sheet.getColumnWidth(i + 1));
        }

        //Save the new workbook to an Excel file
        newBook1.saveToFile("Sales.xlsx", ExcelVersion.Version2016);

        //Copy the header row and range 2 to another workbook, and save it to another Excel file
        Workbook newBook2 = new Workbook();
        sheet.copy(headRow, newBook2.getWorksheets().get(0), 1, 1, true, false);
        sheet.copy(range2, newBook2.getWorksheets().get(0), 2, 1, true, false);
        for (int i = 0; i < sheet.getLastColumn(); i++) {

            newBook2.getWorksheets().get(0).setColumnWidth(i + 1, sheet.getColumnWidth(i + 1));
        }
        newBook2.saveToFile("Technicians.xlsx", ExcelVersion.Version2016);
    }
}

Example 2. Split workbook into separate Excel documents

import com.spire.xls.FileFormat;
import com.spire.xls.Workbook;

public class SplitWorkbook {

    public static void main(String[] args) {

        //Create a Workbook object
        Workbook wb = new Workbook();

        //Load an Excel document
        wb.loadFromFile("C:\\Users\\Administrator\\Desktop\\data.xlsx");

        //Declare a new Workbook variable
        Workbook newWb;

        //Declare a String variable
        String sheetName;

        //Specify the folder path, which is used to store the generated Excel files
        String folderPath = "C:\\Users\\Administrator\\Desktop\\Output\\";

        //Loop through the worksheets in the source file
        for (int i = 0; i < wb.getWorksheets().getCount(); i++) {

            //Initialize the Workbook object
            newWb = new Workbook();

            //Remove the default sheets
            newWb.getWorksheets().clear();

            //Add the the specific worksheet of the source document to the new workbook
            newWb.getWorksheets().addCopy(wb.getWorksheets().get(i));

            //Get the worksheet name
            sheetName = wb.getWorksheets().get(i).getName();

            //Save the new workbook to the specified folder
            newWb.saveToFile(folderPath + sheetName + ".xlsx", FileFormat.Version2013);
        }
    }
}
