Or You can also directly send the file as below Workbook wb = Workbook.getWorkbook(new File("samplefile.xls")) To start with gaining access to Workbook, we should always remember the below command: String FilePath = "d://filepath.xls" įileInputStream fs = new FileInputStream(FilePath) Where as Apache POI supports both Excel 2003 - xls and Excel 2007 - xlsx file formats. It only supports the old BIFF (binary) ".xls" format. You can also consider using Apache Poi Library to perform read and write operations with excel sheets because of its better documentation, more features, active development, and Excel 2007+ format support.Īs we know JXL doesn't support Excel 2007 ".xlsx" file format.

In this article, we will discuss how to access workbook, sheet and a Cell using Jxl library Download jxl jar and add it to build path.
Jxl api maven code#
If you prefer to define the commands in Java code then the template will be the same except you have to remove the comments from the cells.Normally, to read a data in excel, first we should have access to workbook, sheet which we want to read as workbook contains multiple sheets and if you want to read a particular cell we need location of a Cell. By using this class you can define Jxls commands in Excel cell comments. This example assumes usage of XlsCommentAreaBuilder class to construct Jxls areas from the template. The body area of the Each-Command is A4:D4 (defined by the lastCell attribute) and it will be cloned and processed with each new Employee object in the context. The Each-Command will iterate the collection of objects under employees key in Jxls context and place each individual collection item into the context under employee key (defined by var attribute). It defines the root area of our template to be A1:D4.Ī comment to A4 cell defines Jxls Each-Command with the following comment text jx:each(items="employees" var="employee" lastCell="D4"). In the template cells in row 4 we refer to the employee object properties using JEXL expressions as described above.Ĭell A1 contains an excel comment with the following text jx:area(lastCell="D4"). The final template for the example to output a list of Employee objects can be downloaded here and looks like this See Expression Language for more details on how to do it. The property notation is configurable so you may decide to use for example ] as a property notation. We assume that in the context there is an Employee object under the employee key. To output the employee name in a cell we can put the following text in the cell $. The object must be available in Jxls context under a certain key.
Let’s look at the built-in Jxls markup processors.īy default Jxls supports Apache JEXL as an expression language that can be used in an excel template to refer to java object properties and methods.
So one define his own markup for an excel template and parse in a proper way to create Jxls Commands structure. Jxls provides some built-in markup processors which can be used to parse an excel template and extract control commands.Ī custom markup processor can be created if needed. A template is an excel file which uses a special markup to specify how Jxls should output the data.
