I'm wondering if there is a way so that the image that I insert will not stretch like if I insert a 200x200 sized image it will appear to the sheet as 200x200. 回答1: As much as this has bugged me about jxl, I've never found a way to insert an image without associating the aspect ratio to cells instead of pixels/inches/any standard unit of

用Java读取Excel有两种方法，一种方法是JXL，第二种是POI，前者只适用于Excel2007版本以下，后者适用于Excel2007以上和以下。 JXL使用Workbook在不知道单元格文本类型的情况下自动转换成String类型， POI使用了HSSFWorkbook和XSSFWorkbook，只有后者能读取2007版本以上，但比起JXL，它有个明显的缺陷，就是得到的单元格类型必须明确，无法自动转换成String 类型。当读取文件内容比较多时，出现内存溢出的情况，解决方法：Run Configurations —》Argument—》VM argument 输入-Xmx800m 来源： CSDN 作者： perior 链接： https://blog.csdn.net/yxfei666/article/details/6722744

一、读取Excel常用的三种方式（本文讲解97-2003 或更高版本）最底下有码云地址，不用一个个敲 1、POI 2、JXL 3、FASTEXCEL 二、POI Apache POI 是Apache软件基金会的开放源码函式库，POI提供API给java程序对Microsoft Office格式档案读和写的功能 HSSF 是Horrible SpreadSheet Format的缩写，也即 “讨厌的电子表达格式”。通过 HSSF，你可以用纯java代码来读取、写入、修改Excel文件。知识点补充： HSSF - 读写Microsoft Excel 格式档案的功能。 XSSF - 读写Microsoft Excel OOXML格式档案的功能。 HWPF - 读写Microsoft Word 格式档案的功能。 HSLF - 读写Microsoft PowerPoint格式档案的功能。 HDGF - 读写Microsoft Visio格式档案的功能如果想生成 PDF 可以使用 iText 技术通过iText不仅可以生成PDF或者rtf 的文档，而且可以将XML、Html文件转化成PDF文件下载iText.jar 文件以后，只需要在系统的CLASSPATH中加入iText.jar的路径，在程序中就可以使用iText类库了。二、JXL java Execl是一开放的源码项目

Get Excel SheetNames using POI jar

阅读更多关于 Get Excel SheetNames using POI jar

问题 I need all Excel sheet Names (what r all contains the datas) using POI jar. Like jxl jar - getSheetNames() 回答1: You don't say how you want them, so I'll guess at a list. You just need to iterate over the sheet indicies, getting the name for each. Your code would be something like: File myFile = new File("/path/to/excel.xls"); Workbook wb = WorbookFactory.create(myFile); List<String> sheetNames = new ArrayList<String>(); for (int i=0; i<wb.getNumberOfSheets(); i++) { sheetNames.add( wb
