使用Javascript生成CSV

function convertToCSV(data) {
  const csvRows = [];
  const headers = Object.keys(data[0]);
  csvRows.push(headers.join(','));

  for (const row of data) {
    const values = headers.map(header => {
      const escaped = String(row[header]).replace(/"/g, '\\"');
      return `"${escaped}"`;
    });
    csvRows.push(values.join(','));
  }

  return csvRows.join('\n');
}

// 示例数据
const data = [
  { name: 'Alice', age: 25, email: 'alice@example.com' },
  { name: 'Bob', age: 30, email: 'bob@example.com' },
  { name: 'Charlie', age: 35, email: 'charlie@example.com' }
];

const csvContent = convertToCSV(data);

// 下载CSV文件
const blob = new Blob([csvContent], { type: 'text/csv' });
const url = URL.createObjectURL(blob);
const link = document.createElement('a');
link.href = url;
link.download = 'data.csv';
link.click();
