24 January, 2013, 17:25 Hi, there, please help me. I am trying to merge excel files. I read above code. Switch(cell.getCellType) case Cell.CELLTYPEBOOLEAN: System.out.print(cell.getBooleanCellValue + ' t t'); break; case Cell.CELLTYPENUMERIC: System.out.print(cell.getNumericCellValue + ' t t'); break; case Cell.CELLTYPESTRING: System.out.print(cell.getStringCellValue + ' t t'); break; but my cell type is BLANK and I added a new switch case like this: case Cell.CELLTYPEBLANK: System.out.print(cell.getStringCellValue + ' t t'); break; but it doesn’t display me value. How to get value of cell with the type Blank.??????????
I tryied to use cell.getRichStringValue; but unfortunalely it doesn’t help me. That is urgent. Thanks in advance.
26 February, 2013, 12:06 Hi Viral, I need a code for the following problem. I am working on a java application in which i fetch data from multiple tables in the database. The consolidated data is presented in the form of a table in which each row is having an individual checkbox in front.
There is a checkbox at the top also. If user clicks on the topmost checkbox, then all rows get selected. Now i want to export the selected rows(which have data from multiple tables) to an existing excel. The excel has a sheet for each table in the database with columns mapped to the fields in table. The data of the corresponding table should get exported to the corresponding sheets.
In addition, each sheet has some conditional formatting and if the data from the databse doesn’t satisfy that condition then that particular cell should turn red. A cell has a dropdown list of 3 values.
Suppose the data fetched from the database is some other value then that particular cell should turn red. Please provide me code for that. 28 February, 2013, 5:30 Hi All, I have been trying to edit an existing.xlsx file with XSSFWorkbook, getting stuck with this exception when it’s trying to open it. XSSFWorkbook wb = new XSSFWorkbook(new FileInputStream(new File(“existing.xlsx”))); It’s throwing the following exception: java.lang.NumberFormatException: For input string: “A$1” Seems to be that the XSSFWorkbook is complaining about some kind of formatting, or formula from the existing file!?
Any pointers would be greatly appreciated! 18 April, 2013, 21:13 Thanks for the nice examples how to use POI. But I suggest not to create a Workbook for an existing file per new. Instead you should use WorkbookFactory. The important difference is that this approach works with all supported file types – WorkbookFactory creates the appropriate Workbook-Object, either HFFSWorkbook or XSSFWorkbook. Also never use the “HFFS.”-classnames, just use the interface names (without the HFFS-Prefix).
// Get the matching workbook instance for any supported spreadsheet format Workbook workbook = WorkbookFactory.create(file); // Get first sheet from the workbook Sheet sheet = workbook.getSheetAt(0); Best regards, Raimund. 9 May, 2013, 17:02 Hi Patel, It might be helpful if you can explain how to setup this library to some beginners:) let me help you here. You need to follow following steps to get started with above examples 1. You need to download poi-2.5.1.jar(or in this case 3.8) jar file 2. You need to include this file in your projects class path 3. Create new java project in eclipse with auto generated main function 4. Just copy and paste above code or and press ctrl+Shift+o and your ready to go Hope this helps:) Amol Patil findnetinfo.com.
7 October, 2013, 19:54 Hi, Very good information.But i would like to know how to work with multiple sheets in a Workbook. For this again we have to write the total code.I am unable to work with multiple sheets.I am able to read the data by copying the same code and changing the sheet number.But it is showing duplicate code(More lines of code). Can you please suggest me how to do? //Get first sheet from the workbook XSSFSheet sheet = workbook.getSheetAt(0); //Get iterator to all the rows in current sheet Iterator rowIterator = sheet.iterator; //Get iterator to all cells of current row Iterator cellIterator = row.cellIterator. 4 January, 2014, 1:41 This info is excelent, From this article, I have the complete code that writes a new excel with dummy data.
What I need to do in order to work with the same stuff within a JSP web Page? I need to have a link somewhere which points to the JSP that generates the excel file, so the excel file will be generated on the fly, what I need to do?

Thanks in advance. 22 February, 2014, 21:57 Hi Viral, Thank you very much for the very well explanation on Apache POI. Got to learn so many basic things on excel are.
I am executing the code what you have provide above(Reading excel), but getting below error. Tried a lot to fix the issue, but couldn’t find it my self. Can you please help me in fixing this issue. “The type HTMLDocument.Iterator is not generic; it cannot be parameterized with arguments ” “The type HTMLDocument.Iterator is not generic; it cannot be parameterized with arguments ” The error observed in the below two lines: Iterator rowIterator = sheet.iterator; Iterator cellIterator = row.cellIterator. 11 July, 2014, 10:18 Hi Virat, While executing my excel reading code i am getting error as ‘ java.lang.NoSuchMethodError: org.apache.poi.poifs.filesystem.POIFSFileSystem.hasPOIFSHeader(Ljava/io/InputStream;)Z’.
