It is possible to overcome this weak protection level without knowing the password. Hit the edit button to lift the write protection temporarily. The read-only mode can be protected with a password. In Writer and Calc you can specify that some document should always be loaded in read-only mode. Choose the right container, the library and hit the passord button. A Basic library that must not be named 'Standard' can be password protected on the library tab of the macro organizer.

To encrypt document content, check the password option in the save-as dialog and you will be prompted for the encryption password. This level of protection applies to Writer (*.odt), Calc (*.ods), Impress (*.odp), Draw (*.odg) and Math (*.odf) documents. The attachment includes a simple 'hello world' macro in an encrypted library and a calling push button on Sheet3. The libraries can be compiled and called without being able to read the code. If you are a programmer you may be interested in a second protection feature on the same level. It is not possible to decrypt and load the document without entering the Open Sesame password. The content of the attached document is encrypted. LibreOffice shows a colored bar with a push button on top of locked documents. The rightmost button on the screenshot is the edit button. The modified document needs to be saved to another file in some folder where you have write access. However, you get a new, editable copy when you hit the edit button. This occurs with temporary files downloaded from the web and with mail attachments in particular.

In order to work with Excel files, this library provides a series of classes that represent the different parts of an Excel file. 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: String fileLocation = path.substring(0, path.length() - 1) + 'temp.xlsx' įileOutputStream outputStream = new FileOutputStream(fileLocation) Next, let’s write the content of the table in 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()) Sheet sheet = workbook.createSheet('Persons') ĬellStyle headerStyle = workbook.createCellStyle() 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 the 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. 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))
