Nodejs:将列表写入csv

您可以使用csv编写包。

const createCsvWriter = require('csv-writer').createObjectCsvWriter;

let list1= ["label1",100,200,"label2",300,400,"label3",500,600];

let headerRec = [];
let records = [];

for(let i of list1){
 if(typeof(i)=="string"){
   let key = i
   let index = list1.indexOf(i);
   headerRec.push({id:i,title:i}); 
   records.push({[i]:list1[index+1]});
   records.push({[i]:list1[index+2]});
}

}
const csvWriter = createCsvWriter({
  path: './file.csv',
  header: headerRec
});
csvWriter.writeRecords(records)      
.then(() => {
    console.log('...Done');
});
