从Gmail CSV文件Google Apps脚本导入的追加日期列到数组中

Question

我正在尝试将通过第三方系统（无法编辑所发送的值）通过电子邮件发送的每日报告自动导入到Google工作表中，以便随着时间的推移创建报告。

下面的代码可以正常工作并正确导入数据，但是CSV文件不包含不可能进行报告的日期。

我可以从电子邮件中获取日期，并且再次可以使用，但是我无法将其附加到写入工作表的数据中。理想情况下，代码将在带有日期的数组的每个元素的开头添加一个额外的条目。

/**
 * import CSV data directly from gmail attachments
 */
function importCSVFromGmail() {

  var threads = GmailApp.search('subject:Agent Performance report for newer_than:1d');

  // create empty array to hold data
  var allData = [];

  // get the threads that match this search
  threads.forEach(function(thread) {

    var messageCount = thread.getMessageCount();

    // get the messages in a thread
    var messages = thread.getMessages();

    messages.forEach(function(message) {

      var attachments = message.getAttachments();

      attachments.forEach(function(attachment) {

        // check attachment is CSV
        if (attachment.getContentType() === 'text/csv') {

          // extract the data
          var csvData = Utilities.parseCsv(attachment.getDataAsString());
          var date = Utilities.formatDate(new Date(message.getDate()), "GMT+1", "MM/dd/yyyy");

          allData = allData.concat(csvData);

        }
      });  
      Logger.log(allData);
    }); 
  });

  // paste into Google Sheet
  var sheet = SpreadsheetApp.getActiveSheet();
  var lastRow = sheet.getLastRow();
  sheet.getRange(lastRow + 1, 1, allData.length, allData[0].length).setValues(allData);
}

CSV数据样本

Agent,Tickets assigned,Tickets resolved,Tickets reopened,Tickets reassigned,First response SLA %,Resolution SLA %,FCR %,Private notes,Responses,Average 1st response time,Average response time,Average resolution time
Agent 1,1,2,,1,,100,100,,1,,,17:32:49
Agent 2,11,14,3,,88,86,67,3,15,06:09:35,04:04:20,19:44:18
Agent 3,18,25,7,,100,80,68,6,14,01:28:29,02:35:47,74:48:48

期望的输出将只是CSV文件中的数据，第一列中的日期是

DD/mm/yyyy,Agent,Tickets assigned,Tickets resolved,Tickets reopened,Tickets reassigned,First response SLA %,Resolution SLA %,FCR %,Private notes,Responses,Average 1st response time,Average response time,Average resolution time
DD/mm/yyyy,Agent 1,1,2,,1,,100,100,,1,,,17:32:49
DD/mm/yyyy,Agent 2,11,14,3,,88,86,67,3,15,06:09:35,04:04:20,19:44:18
DD/mm/yyyy,Agent 3,18,25,7,,100,80,68,6,14,01:28:29,02:35:47,74:48:48

Answer 1

使用Array.unshift for each行：

const csvData = Utilities.parseCsv(attachment.getDataAsString());
const date = Utilities.formatDate(new Date(message.getDate()), "GMT+1", "MM/dd/yyyy");
csvData.forEach(row => row.unshift(date));
