nodejs简单读写excel内容的方法示例

var xlsx = require('node-xlsx');
var fs = require('fs');
//读取文件内容
var obj = xlsx.parse(__dirname+'/test.xlsx');
var excelObj=obj[0].data;
console.log(excelObj);
var data = [];
for(var i in excelObj){
  var arr=[];
  var value=excelObj[i];
  for(var j in value){
    arr.push(value[j]);
  }
  data.push(arr);
}
var buffer = xlsx.build([
  {
    name:'sheet1',
    data:data
  }
]);
//将文件内容插入新的文件中
fs.writeFileSync('test1.xlsx',buffer,{'flag':'w'});
