如何在JS中用对象元素填充CSV文件

// 示例对象数组
const data = [
  { name: 'John', age: 25, city: 'New York' },
  { name: 'Jane', age: 30, city: 'San Francisco' },
  { name: 'Bob', age: 35, city: 'Seattle' }
];

// 获取列名数组
const headers = Object.keys(data[0]);

// 将对象数组转换为以逗号分隔的字符串数组
const csvData = data.map(obj => headers.map(header => obj[header]).join(','));

// 将字符串数组连接成一个以换行符分隔的字符串
const csvString = headers.join(',') + '\n' + csvData.join('\n');

// 打印生成的CSV字符串
console.log(csvString);

name,age,city
John,25,New York
Jane,30,San Francisco
Bob,35,Seattle
