本文实例讲述了java简单解析xls文件的方法。分享给大家供大家参考，具体如下：

读取：

import java.io.*;

import jxl.*;

import jxl.write.*;

import jxl.format.*;

class Aa{

public static void main(String args[]) {

try{

Workbook workbook = null;

try {

workbook = Workbook.getWorkbook(new File("d:\\a.xls"));

} catch (Exception e) {

throw new Exception("file to import not found!");

}

Sheet sheet = workbook.getSheet(0);

Cell cell = null;

int columnCount=3;

int rowCount=sheet.getRows();

for (int i = 0; i

for (int j = 0; j

//注意，这里的两个参数，第一个是表示列的，第二才表示行

cell=sheet.getCell(j, i);

//要根据单元格的类型分别做处理，否则格式化过的内容可能会不正确

if(cell.getType()==CellType.NUMBER){

System.out.print(((NumberCell)cell).getValue());

}

else if(cell.getType()==CellType.DATE){

System.out.print(((DateCell)cell).getDate());

}

else{

System.out.print(cell.getContents());

}

//System.out.print(cell.getContents());

System.out.print("\t");

}

System.out.print("\n");

}

//关闭它，否则会有内存泄露

workbook.close();

}catch(Exception e){

}

}

}

写入：

import java.io.*;

import jxl.*;

import jxl.write.*;

import jxl.format.*;

class Aa{

public static void main(String args[]) {

try{

File tempFile=new File("d:" + java.io.File.separator + "output00.xls");

System.out.println( "d:" + java.io.File.separator + "output00.xls" );

WritableWorkbook workbook = Workbook.createWorkbook(tempFile);

WritableSheet sheet = workbook.createSheet("TestCreateExcel", 0);

//一些临时变量，用于写到excel中

Label l=null;

jxl.write.Number n=null;

jxl.write.DateTime d=null;

//预定义的一些字体和格式，同一个Excel中最好不要有太多格式

WritableFont headerFont = new WritableFont(WritableFont.ARIAL, 12, WritableFont.BOLD, false, UnderlineStyle.NO_UNDERLINE, jxl.format.Colour.BLUE);

WritableCellFormat headerFormat = new WritableCellFormat (headerFont);

WritableFont titleFont = new WritableFont(WritableFont.ARIAL, 10, WritableFont.NO_BOLD, false, UnderlineStyle.NO_UNDERLINE, jxl.format.Colour.RED);

WritableCellFormat titleFormat = new WritableCellFormat (titleFont);

WritableFont detFont = new WritableFont(WritableFont.ARIAL, 10, WritableFont.NO_BOLD, false, UnderlineStyle.NO_UNDERLINE, jxl.format.Colour.BLACK);

WritableCellFormat detFormat = new WritableCellFormat (detFont);

NumberFormat nf=new NumberFormat("0.00000"); //用于Number的格式

WritableCellFormat priceFormat = new WritableCellFormat (detFont, nf);

DateFormat df=new DateFormat("yyyy-MM-dd");//用于日期的

WritableCellFormat dateFormat = new WritableCellFormat (detFont, df);

//剩下的事情，就是用上面的内容和格式创建一些单元格，再加到sheet中

l=new Label(0, 0, "用于测试的Excel文件", headerFormat);

sheet.addCell(l);

//add Title

int column=0;

l=new Label(column++, 2, "标题", titleFormat);

sheet.addCell(l);

l=new Label(column++, 2, "日期", titleFormat);

sheet.addCell(l);

l=new Label(column++, 2, "货币", titleFormat);

sheet.addCell(l);

l=new Label(column++, 2, "价格", titleFormat);

sheet.addCell(l);

//add detail

int i=0;

column=0;

l=new Label(column++, i+3, "标题 "+i, detFormat);

sheet.addCell(l);

d=new DateTime(column++, i+3, new java.util.Date(), dateFormat);

sheet.addCell(d);

l=new Label(column++, i+3, "CNY", detFormat);

sheet.addCell(l);

n=new jxl.write.Number(column++, i+3, 5.678, priceFormat);

sheet.addCell(n);

i++;

column=0;

l=new Label(column++, i+3, "标题 "+i, detFormat);

sheet.addCell(l);

d=new DateTime(column++, i+3, new java.util.Date(), dateFormat);

sheet.addCell(d);

l=new Label(column++, i+3, "SGD", detFormat);

sheet.addCell(l);

n=new jxl.write.Number(column++, i+3, 98832, priceFormat);

sheet.addCell(n);

//设置列的宽度

column=0;

sheet.setColumnView(column++, 20);

sheet.setColumnView(column++, 20);

sheet.setColumnView(column++, 10);

sheet.setColumnView(column++, 20);

workbook.write();

workbook.close();

}catch(Exception e){

}

}

}
