将csv文件转换为javascript对象

const fs = require('fs');
const csvParser = require('csv-parser');

function convertCsvToObj(csvFilePath) {
  const csvData = fs.readFileSync(csvFilePath, 'utf-8');
  const results = [];

  return new Promise((resolve, reject) => {
    fs.createReadStream(csvFilePath)
      .pipe(csvParser())
      .on('data', (data) => {
        results.push(data);
      })
      .on('end', () => {
        const convertedObj = results.map(row => {
          const obj = {};
          for (const key in row) {
            obj[key] = row[key];
          }
          return obj;
        });
        resolve(convertedObj);
      })
      .on('error', reject);
  });
}

// 调用示例
convertCsvToObj('data.csv')
  .then((convertedData) => {
    console.log(convertedData);
  })
  .catch((error) => {
    console.error(error);
  });
