Writing and reading a simple spreadsheet import java.io.File To help you get started with JExcelAPI, I've created a simple JExcelAPIDemo application that demonstrates creating a new spreadsheet that is saved in output.xls and then reading and outputting the contents of this spreadsheet. To learn about additional packages, execute jar tvf jxl.jar and examine the package information in the resulting JAR listing. Additional packages such as jxl.read are present but are not documented.

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.
