问题 How to autofit content in cell using jxl api? 回答1: I know this is an old question at this point, but I was looking for the solution to this and thought I would post it in case someone else needs it. CellView Auto-Size I'm not sure why the FAQ doesn't mention this, because it very clearly exists in the docs. My code looked like the following: for(int x=0;x<c;x++) { cell=sheet.getColumnView(x); cell.setAutosize(true); sheet.setColumnView(x, cell); } c stores the number of columns created cell

How to process old excel .xls files using POI?

风格不统一 提交于 2019-11-29 09:07:22
I switched from jxl to poi since POI has more features. However, I wasn't able to process the xls files that were generated in the old format. Now I am getting this error: org.apache.poi.hssf.OldExcelFormatException: The supplied spreadsheet seems to be Excel 5.0/7.0 (BIFF5) format. POI only supports BIFF8 format (from Excel versions 97/2000/XP/2003) Now I am thinking to use both JXL as wells as POI depending on the xls version so for old format xls files I will use jxl while for newer versions I will use POI. Is this a good solution? Are there any alternatives? For old Excel format files, you

jxl读取excel文件异常:Unable to recognize OLE stream 的解决方法

本文链接:https://blog.csdn.net/u011032676/article/details/50989465 问题成因 使用jxl方式读取,可能只能支持xls格式的文件,对于xlsx格式就不再支持 如果是从网站导出的excel文件,有的网站比较坑,导出的并不是标准格式的excel,而是将html改扩展名为xls的“伪”excel文件。当用excel打开这类文件时,会弹窗提示其“扩展名和文件类型不匹配”是否还要打开。 而且,使用文本编辑器打开,会发现这个所谓xls文件其实是xml标签的文件。 解决方法 在excel中打开,另存成xls就可以。 但当文件比较多时,可以使用excel vba批量另存。 第一种情况直接用vba批量另存即可,但第二种略有麻烦,因为会有报错弹窗,vba运行时会报错。 下面以第二种情况为例详细说明解决步骤。 首先,需要禁止excel的报错弹窗,否则使用vba批量另存时会出错。方法如下: 1、开始 -> 运行 -> 输入regedit -> 确定 2、找到注册表子项 HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Excel\Security 3、在右侧空白处点击鼠标右键,选择“新建 -> DWORD值(D)”,输入"ExtensionHardening"点击确定。 4

I have learnt to read and write an Excel file using a Java program with the help of Jxl and POI API. Is it possible to run a Java program with the help of macros? Margus Yes, it is possible. There are quite a few ways actually and I hope you like my examples. To demonstrate this, I create a program where some text is send as arguments and program responds with an altered version of it. I made a runnable jar of it. First example reads the argument from args and other from standard input.
