问题 The strings I'm (programmatically) getting from MS Word files when using Apache POI are not the same text I can look at when I open the files with MS Word. When using the following code: File someFile = new File("some\\path\\MSWFile.doc"); InputStream inputStrm = new FileInputStream(someFile); HWPFDocument wordDoc = new HWPFDocument(inputStrm); System.out.println(wordDoc.getText()); the output is a single line with many 'invalid' characters (yes, the 'boxes'), and many unwanted strings, like

问题 Calling Simple toBytes() does produce the bytes but exel throws Warning. Lost Document information Googling around gave me this link and looking at Javadocs for worksheet and POI HOW-TO say similar things . Basically I can not get Bytes without loosing some information and should use the write method instead. While write does work fine I really need to send the bytes over . Is there any way I can do that ? That is get the bytes with out getting any warning . 回答1: As that mailing list post

问题 I am working on converting an Excel VBA Script to Java using Apache POI and I am stuck. In VBA it is easy to apply both Fill Colors and Borders to cells in succession. But in POI it seems almost impossible without creating hundreds of XSSFCellStyles [(Every Color Used) x (Every Border Combination) x (Every Font Used)]. I am trying to recreate this spreadsheet, which is currently produced via VBA: Spreadsheet Image The code below is intended to begin formatting by filling the top two rows gray

问题 I want to write some records into excel but I got to know that the maximum cell styles in XSSFWorkbook is 64000 .But records exceeding more than 64000 and consider I want to apply new cellstyle to each cell or I will clone with the already existing cell style. Even to clone I need to take default cell style workbook.createCellStyle(); but this exceeds for 64001 record which leads to java.lang.IllegalStateException: The maximum number of cell styles was exceeded. . So is there anyway in POI to

If you have CF10 then you might be in luck 'cause that should be fixed now (as of Update 10 at least). 来源： https://stackoverflow.com/questions/19214735/data

问题 Is it possible to extract chart information from an Office 2007 (xlsx / OpenXML) spreadsheet using Apache POI? I've managed to read in the spreadsheet and even get the part that refers to the chart but not sure how I can retrieve any info from this part e.g. Type of chart, chart data etc. XSSFWorkbook xwb = new XSSFWorkbook("charts_lines.xlsx"); XSSFSheet sheet = xwb.getSheetAt(0); I can also iterate through the package parts to retrieve the chart part, but I don't see how I then go on to
