xssf

Excel has different modes for viewing a sheet: Normal, Page Layout, Page Break Preview. (In excel 2010: in the view tab). The view mode is saved seperately for each sheet in a workbook and is restored when opened again. I am trying to find a way to set a view mode using Either HSSF or XSSF. In the old binary format, finding the answer seems quite impossible unfortunately. In 2007+ OOXML format diffing does give the basic answer, looking at xl/worksheets/sheet1.xml In normal view: <sheetViews> <sheetView rightToLeft="1" tabSelected="1" zoomScaleNormal="100" workbookViewId="0"> </sheetViews> In

I am getting this error: org.apache.poi.poifs.filesystem.OfficeXmlFileException: The supplied data appears to be in the Office 2007+ XML. You are calling the part of POI that deals with OLE2 Office Documents. You need to call a different part of POI to process this data (e.g. XSSF instead of HSSF) I read throw Google and I found out that I need to use XSSF instead of HSSF because my Excel file is xlsx, but as you see in my maven, I am already using xlsx. Where have I gone wrong please? <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>3.13-beta1<

I am trying to hyperlink a .png file in a cell content of any .xlsx file. Following is the part of code and it is showing java.net.URISyntaxException exception (seems because of slash used in the address). However changing link.setAddress("test.png") is not showing any error, but it is not resolving my purpose. Please help me. public static void main(String[]args) throws Exception{ XSSFWorkbook wb = new XSSFWorkbook(); CreationHelper createHelper = wb.getCreationHelper(); CellStyle hlink_style = wb.createCellStyle(); Font hlink_font = wb.createFont(); hlink_font.setUnderline(Font.U_SINGLE);

I need to create a drop down list in excel file using Apache POI. and I am able to do that so But I am not able to make first item in drop down list as default Item. public class sd { /** * @param args * @throws IOException */ public static void main(String[] args) throws IOException { DataValidation dataValidation = null; DataValidationConstraint constraint = null; DataValidationHelper validationHelper = null; XSSFWorkbook wb = new XSSFWorkbook(); XSSFSheet sheet1=(XSSFSheet) wb.createSheet("sheet1"); validationHelper=new XSSFDataValidationHelper(sheet1); CellRangeAddressList addressList =

I am using the following code: File file = new File("abc.xlsx"); InputStream st = new FileInputStream(file); XSSFWorkbook wb = new XSSFWorkbook(st); The xlsx file itself has 25,000 rows and each row has content in 500 columns. During debugging, I saw that the third row where I create a XSSFWorkbook, it takes a lot of time (1 hour!) to complete this statement. Is there a better way to access the values of the original xlsx file? First up, don't load a XSSFWorkbook from an InputStream when you have a file! Using an InputStream requires buffering of everything into memory, which eats up space and
