I have been trying to segment a docx document to multiple documents based on a predefined criteria. following is my approach to cut it to paragraphs try { FileInputStream in = new FileInputStream(file); XWPFDocument doc = new XWPFDocument(in); List<XWPFParagraph> paragraphs = doc.getParagraphs(); for (int idx = 0; idx < paragraphs.size(); idx++) { XWPFDocument outputDocument = new XWPFDocument(); createParagraphInAnotherDocument(outputDocument, paragraphs.get(idx).getText()); String fullPath = String.format("./content/output/%1$s_%2$s_%3$04d.docx", FileUtils.getFileName(file), getName(), idx);

I'm trying to read an excel file (xlsx NOT xls) but without any luck. I tried the jexcel api but it doesn't support xlsx extension, then I tried the Apache api which need to work and tried also the example from their web site but with no luck.I can't pass the read file phase and get a filenotfound exception. also used the poi-ooxml-3.6.jar,xmlbeans-2.6.0 and poi-3.7.jar. can anyone please explain to me what types of api/classes/libraries I need to use and how to use it with eclipse (the external libraries/classes/api is totally new to me) many thanks in advance Benoit Wickramarachi Apache POI

The scenario is roughly this: I have a java program with several methods getting called randomly. The first method will create an xls file using apache POI and will put the headers for the columns. All the other methods has to write a record into this file. The final method will first mail the created xls and then delete the xls. For above scenario is the below approach correct: 1) Create the file and put the header names in the first method: Workbook wb = new HSSFWorkbook(); CreationHelper createHelper = wb.getCreationHelper(); Sheet sheet = wb.createSheet("First Sheet"); Row row = sheet

HSSF is the POI Project's pure Java implementation of the Excel '97(-2007) file format. XSSF is the POI Project's pure Java implementation of the Excel 2007 OOXML (.xlsx) file format. Are there any export limitations when using HSSF? I've once read somewhere that Excel '97 just supported <65.000 Entries . Is it safe to use HSSF to export excel sheets with more than 65.000 Entries, or why would I use XSSF? As you can see here Excel 97 to 2003 supports a maximum of 65,536 rows. So no, with HSSF you won't be able to store more than 65536 entries. However you can do it with XLSX (Excel 2007+)

How to delete contents of an Excel sheet in an Excel workbook, using Java SE and Apache POI? As mentioned in previous comments Sheet sheet = wb.getSheetAt(0); for (Row row : sheet) { sheet.removeRow(row); } this code throwing ConcurrentModificationException to me. So, I have modified the code and it's working fine. Here is the code: Sheet sheet = wb.getSheetAt(0); Iterator<Row> rowIte = sheet.iterator(); while(rowIte.hasNext()){ rowIte.next(); rowIte.remove(); } I've found that removeSheetAt/createSheet isn't really an acceptable answer, because you can't put the new sheet into the correct

I'm trying to develop a complex report, and I need to set up the print areas for the excel file. I must divide the xls file in 3 part, but if I do setPrintArea(..) the new area subscribe the old and the result is that I have in the print preview only the last page. How can I set more than one print area? This is the code: protected void createCustomerSheet(String label) { createSheet(label); getCurrentSheet().getPrintSetup().setPaperSize(PrintSetup.A4_PAPERSIZE); getCurrentSheet().getPrintSetup().setFitHeight((short)1); getCurrentSheet().getPrintSetup().setFitWidth((short)1); getCurrentSheet()

Im using an xlsx file that contains a DATE(year, month, day) formula within a cell. This cell is formatted as date, so Excel/OpenOffice shows the proper date. e.g. the cell content is '=DATE(2013;1;1)' which produces : '01.01.2013' So far - so good. When reading this file with the poi library I do: XSSFWorkbook workbook = new XSSFWorkbook(new FileInputStream(new File("/home/detlef/temp/test.xlsx"))); XSSFSheet sheet = workbook.getSheet("Sheet A"); XSSFCell cell = sheet.getRow(0).getCell(0); System.out.println(cell.getDateCellValue()); This will print out: Sun Dec 31 00:00:00 CET 1899 I am
