Image credit is listed at the end of this article.

Java Excel API (a.k.a. JXL API) allows users to read, write, create, and modify sheets in an Excel (.xls) workbook at runtime. It does not support .xlsx format.

01Microsoft Excel support

Java Excel API supports Excel documents with versions Excel 95, 97, 2000, XP, and 2003. These documents hold the extension .xls.

02Usage

Java Excel API is widely used with Selenium.

Example

Sample code to write to an Excel file might look like as follows:

import java.io.File; import jxl.Workbook; import jxl.write.WritableSheet; import jxl.write.WritableWorkbook; import jxl.write.Label; import jxl.write.WriteException; public class DataSheet { private Workbook wbook; private WritableWorkbook wwbCopy; private WritableSheet shSheet; public void readExcel() { try { wbook = Workbook.getWorkbook(new File("path/testSampleData.xls")); wwbCopy = Workbook.createWorkbook(new File("path/testSampleDataCopy.xls"), wbook); shSheet = wwbCopy.getSheet(0); } catch (Exception e) { e.printStackTrace(); } } public void setValueIntoCell(String strSheetName, int iColumnNumber, int iRowNumber, String strData) throws WriteException { WritableSheet wshTemp = wwbCopy.getSheet(strSheetName); Label labTemp = new Label(iColumnNumber, iRowNumber, strData); try { wshTemp.addCell(labTemp); } catch (Exception e) { e.printStackTrace(); } } public void closeFile() { try { // Closing the writable work book wwbCopy.write(); wwbCopy.close(); // Closing the original work book wbook.close(); } catch (Exception e) { e.printStackTrace(); } } public static void main(String[] args) throws WriteException { DataSheet ds = new DataSheet(); ds.readExcel(); ds.setValueIntoCell("sheet1", 5, 1, "PASS"); ds.setValueIntoCell("sheet1", 5, 2, "FAIL"); ds.setValueIntoCell("sheet1", 5, 3, "PASS"); ds.closeFile(); } }
