我正在向这个函数传递一个文件，我想将数据转换为json，但对于特定的列DOB 05-04-2001，转换为随机数，如36986。我希望输入准确的日期作为此函数的响应，如何操作？谁能帮我一下YRR。

static convertExcelFileToJsonUsingXlsxTrimSpaces = (path: string) => {
    // Read the file using pathname
    const file = xlsx.readFile(path);

    // Grab the sheet info from the file
    const sheetNames = file.SheetNames;
    const totalSheets = sheetNames.length;

    // Variable to store our data
    const parsedData: any[] = [];

    // Loop through sheets
    for (let i = 0; i < totalSheets; i += 1) {
      // Convert to json using xlsx

      const sheetData = xlsx.utils.sheet_to_json(file.Sheets[sheetNames[i]], { raw: true });

      console.log(sheetData);

      // Process each row to handle tab-separated values
      const processedData: any[] = [];
      sheetData.forEach((row: any) => {
        const processedRow: any = {};
        Object.keys(row).forEach((key) => {
          processedRow[key] = row[key].toString().trim(); // Convert to string and trim whitespace
        });
        processedData.push(processedRow);
      });

      // Add the sheet's processed data to our data array
      parsedData.push(...processedData);
    }

    return parsedData;
  };
