I access an Excel spreadsheet using Java Apache POI ( hssf ). I got the following error : java.lang.RuntimeException: 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.

I'm facing an issue when opening a excel file with hundreds/thousands of rows of data, "Too Many Different Cell Formats" More info about the error http://excelzoom.com/2009/09/the-mystery-of-excels-too-many-different-cell-formats/ So I'm trying to format a column not a cell.

I have hundreds/thousands of rows of data to format. Any suggestions would be very much appreciated. Thanks, HSSFCellStyle cellStyle = wb

I am still new to java. I am having a bit problems with the java syntax. My Program should do the following procedure: 1) It takes a csv file as an input. 2) It takes an excel file as an input. 3) It should iterate over the first columns of the two files where the dates are written. 4) Update the excel file by adding the information from the csv sheet and save its changes. I have a https://onedrive.live.com/?cid=24b4fceb4f4e4098&id=24B4FCEB4F4E4098%213018&authkey=%21AKKzaZsJ5pkd5NE where I have the two input examples and how the result excel sheet should look like.

Until now apache poi does only supporting line chart and scatter chart but not bar chart directly. So creating a bar chart is only possible using the underlaying low level objects. For a reference do starting with org.openxmlformats.schemas.drawingml.x2006.chart.CTChart . Example code which

Which is better API for excel parsing in Java Apache POI or JExcel API? In terms of speed, memory utilization and code stability. Personally I would recommend POI over JExcel. The reasons I chose POI over JExcelAPI are: POI supports both old and new MS Excel sheet formats It has a cleaner API (imho) As far as I can see it does not suffer from the irritating Date\Time issues that JexcelApi has ( Date display ).
