Let's test the above methods in a JUnit test that writes content to the temp.xlsx file and then reads the same file to verify it contains the text we have written: Plugin for webpack that converts your images to next gen image formats (JPEG-XL, AVIF, WebP) and puts them in a picture element with fallback to a well supported format (JPEG, PNG or GIF). Package jxl.install Description Install is a simple library to collect and record a directory to persist data. String fileLocation = path.substring(0, path.length() - 1) + "temp.xlsx" įileOutputStream outputStream = new FileOutputStream(fileLocation) Next, let's write the content of the table with a different style: CellStyle style = workbook.createCellStyle() įinally, let's write the content to a “temp.xlsx” file in the current directory and close the workbook: File currDir = new File(".") XSSFFont font = ((XSSFWorkbook) workbook).createFont() tFillPattern(FillPatternType.SOLID_FOREGROUND) tFillForegroundColor(IndexedColors.LIGHT_BLUE.getIndex()) JExcelApi is a java library which provides the ability to read, write, and modify Microsoft Excel spreadsheets.

Let's create a method that writes a list of persons to a sheet titled “Persons”.įirst, we will create and style a header row that contains “Name” and “Age” cells: Workbook workbook = new XSSFWorkbook() When the cell type enum value is STRING, the content will be read using the getRichStringCellValue() method of Cell interface: data.get(new Integer(i)).add(cell.getRichStringCellValue().getString()) Ĭells having the NUMERIC content type can contain either a date or a number and are read in the following manner:Īpache POI uses the same interfaces presented in the previous section for writing to an Excel file and has better support for styling than JExcel. Download A Java library for reading/writing Excel for free. Let's expand on the content of each switch case above. Next, let's retrieve the first sheet of the file and iterate through each row: Sheet sheet = workbook.getSheetAt(0) ĭefault: data.get(new Integer(i)).add(" ") Īpache POI has different methods for reading each type of data. Workbook workbook = new XSSFWorkbook(file) First, let's open the file from a given location: FileInputStream file = new FileInputStream(new File(fileLocation))
