问题 I want to edit an existing Excel file with Java, to add some more data to an existing template excel file. So i used Jexcel for this purpose. As suggested everywhere, I tried the following, Workbook existingWorkbook = Workbook.getWorkbook(new File("H://"+file_name)); WritableWorkbook copy = Workbook.createWorkbook(new File("H://"+file_name+"_temp1.xls")); But it shows an exception in the second line. jxl.common.AssertionFailed at jxl.common.Assert.verify(Assert.java:37) at jxl.read.biff

Making new colors in JExcelApi

由 谁都会走 提交于 2019-12-10 02:56:30
问题 I'm using JExcelApi for generating XLS files.

But in Excel itself, I can pick any color at all. Am I just missing it? Is there a way in JExcelApi to select an arbitrary color? I'm using a simple find-the-closest-standard-color method right now, which is OK but not great. 回答1: Excel versions before 2007 have a standard palette, and given

Which library should I use to write an XLS from Linux / Python?

问题 I'd love a good native Python library to write XLS, but it doesn't seem to exist. Happily, Jython does. So I'm trying to decide between jexcelapi and Apache HSSF: http://www.andykhan.com/jexcelapi/tutorial.html#writing http://poi.apache.org/hssf/quick-guide.html (I can't use COM automation because I'm not on Windows, and even if I was, I couldn't afford Office licenses.) My initial thoughts are that POI/HSSF is very thorough, but also very Java-- everything seems a bit harder than it needs to

Is there any Java library which supports both Microsoft office and Open Office?

由 心已入冬 提交于 2019-12-07 17:03:42
问题 As Apache POI supports Microsoft office and JExcelApi supports Open Office, is there any Java library which supports both Microsoft office and Open Office?

So my question: Is there any library which supports both? 回答1: Aspose covers all of Microsofts formats, but it is not free and not open source. Regarding open source Java
