#Java jxl how to#
The tutorial shows you how to read, write, and copy spreadsheets. Q: How do I create Java programs that leverage JExcelAPI?Ī: The jexcelapi home directory includes a tutorial.html file that presents a basic tutorial on programming with JExcelAPI.

Q: How do I include JExcelAPI when compiling source code and running an application?Ī: To include JExcelAPI when compiling source code and running an application, do one of the following: Including JExcelAPI for compilation and execution Click the original and modified tabs to view the original and modified sheets Figure 2 shows the second (modified) sheet in LibreOffice Calc. This command line copies jxlrwtest.xls to copy.xls. Consider the following command line: java -jar jxl.jar -rw jxlrwtest.xls copy.xls This demo is generated by specifying the -rw command-line option followed by jxlrwtest.xls and the name of the output spreadsheet. In the resulting spreadsheet, the first sheet (original) is unchanged whereas the second sheet (modified) contains modified values. The copy demo copies sample spreadsheet jxlrwtest.xls, which is stored in the same directory as jxl.jar, to a new spreadsheet. I used LibreOffice Calc to access the sample.xls spreadsheet This spreadsheet is generated by specifying the -write command-line option, as demonstrated below: java -jar jxl.jar -write sample.xlsįigure 1 shows part of the resulting sample.xls spreadsheet. The write demo creates a sample spreadsheet that includes formulae, borders, images, and more. When neither -csv nor -xml is specified, -csv is assumed. These examples read budget.xls and output its contents in CSV and XML format to standard output. Consider the following examples: java -jar jxl.jar -csv budget.xls

The read demo reads an existing spreadsheet, converting it to comma-separated value (CSV) or XML format via the -csv or -xml command-line option. Q: Does the JExcelAPI library contain any demos?Ī: JExcelAPI's jexcelapi home directory contains a jxl.jar file that contains demos for reading, writing, and copying spreadsheets. You should observe a jexcelapi home directory within a jexcelapi_2_6_12 directory. Go ahead and save the file.įollowing the download, unarchive this file.

The suggested workaround for unsupported features is to create an object manually in an Excel template and fill in the template with data after that. In addition not all Excel features are supported and can be manipulated with libraries API (e.g. Depending on the complexity of the report layout and data formatting the Java code can become quite complex and difficult to debug and maintain. Usually one has to manually set each cell formatting and data for the spreadsheet. Those libraries are great but quite low-level as they require a developer to write a lot of Java code even to create a simple Excel file. Java has a few libraries for creating Excel files e.g. Jxls uses a special markup in Excel templates to define output formatting and data layout.Įxcel generation is required in many Java applications that have some kind of reporting functionality. Jxls is a small Java library to make generation of Excel reports easy.
