The conversion method is similar below. The Code is as follows: HSSFWorkbook hssfWorkbook = new HSSFWorkbook (); ISheet sheet = hssfWorkbook. createSheet ("Sheet1"); // you can specify the width of the first column (Cell. setColumnWidth (0, 5000); // create and format the Instance Object

Npoi Introduction-------------------------------------------------------------------------------- 1. The entire Excel table is called a worksheet: WorkBook (working thin), including a page (worksheet): Sheet; Row: Row; Cell. 2. Npoi: http://npoi.codeplex.com/releases/view/38113 4. I forgot to tell you What npoi is doing. npoi can read and write almost all Office 97-2003 file formats. At least it can support Word, PowerPoint, Excel, and Visio formats. ---------------------------------------------

Recently, a project needs to import some data. Some of the imported data uses the Excel percentage and some data uses the string format, (data comes from statistics by different people.) The format is slightly messy. When importing data to the system, convert all the percentage data into percent data for storage. Because the component npoi used in the previous project to read excel, I directly used npoi to read it. The npoi I used is of Version 2.0, which is not too new. During regular read oper

In the operation of Excel, some special value conversion is unavoidable, the following gives the conversion method is similar, the code is as follows: Hssfworkbook Hssfworkbook =NewHssfworkbook (); Isheet sheet= Hssfworkbook.createsheet ("Sheet1");//Set the first column (Cell) widthSheet.
