Question

我每小时在Google云端硬盘中收到一个新的CSV文件。在Google云端硬盘文件夹中收到电子表格后，我需要使用最新CSV文件中的数据更新电子表格。

根据日期和时间，进入该文件夹的文件对于每个新文件都有一个唯一的名称。例如：FileName_date_24hourtime.csv FileName_20190524_1800.csv，然后FileName_20190524_1900.csv等。

首先，我不确定最好的方法是什么

仅带有一个公式（可能不知道确切的文件名就不可能？），例如= IMPORTDATA
一个Google脚本，用于查找最新的.csv文件并在文件添加到Google云端硬盘文件夹后自动导入

任何帮助都会很棒！

.csv文件： .csv文件包含28行，数据应按分割； .csv文件如下所示：名称; -63.06; -58.08; 50.62; -66.67; -80.00 名称; -61.82; -56.83; -50.55; -77.78; -70.00 名称; -57.77; -50.21; 52.88; -77.78; -70.00 NAME1; -57.69; -61.48; -55.59; -55.56; -60.00 NAME2; -61.62; -53.79; 50.34; -66.67; -70.00 NAME3; -54.62; -54.57; -52.22; 55.56; -60.00 ...总共28行

数据应转到“导入统计信息”表。

最好的方法是使用带有触发器的脚本，该触发器具有执行将数据导入电子表格的功能。

创建具有1小时偏移的基于时间的触发器：

function trigger() {
  var trg = ScriptApp.newTrigger('checkFiles');
      trg.timeBased().everyHours(1).create();
}

创建用于检查文件夹中文件（例如“ checkFiles”）的功能。

function checkFiles(alreadyWaited) {
  //get spreadsheet and sheet;
  var id = 'yourSpreadsheetId';
  var ss = SpreadsheetApp.openById(id);
  var sh = ss.getSheetByName('Import_Stats');    

  var folderId = 'yourIdHere'; //folder by id is the simplest way;

  //get folder and files in it;
  var folder = DriveApp.getFolderById(folderId);
  var files       = folder.getFilesByType('text/csv');
  var filesImport = folder.getFilesByType('text/csv'); //fetch files again;

  //try to fetch number of files;
  var scriptProps = PropertiesService.getScriptProperties();
  var numFiles = scriptProps.getProperty('numFiles');

  //count current number of files;
  var numCurr = 0;
  while(files.hasNext()) {
  var f = files.next();
  numCurr++;
  }

  //if this is the first time, save current number;
  if(numFiles===null) { 
    scriptProps.setProperty('numFiles',numCurr);
  }else {
    numFiles = parseInt(numFiles);
  }

  if(numFiles===null||numFiles===(numCurr-1)) {

    //get today and reset everything except hours;
    var today = new Date();
        today.setMinutes(0);
        today.setSeconds(0);
        today.setMilliseconds(0);      

    //iterate over files;
    while(files.hasNext()) {
      var file = files.next();

      //get file creation date and reset;
      var created = file.getDateCreated();
          created.setMinutes(0);
          created.setSeconds(0);
          created.setMilliseconds(0);

      //calculate offset, equals 0 for each file created this hour;
      var offset = today.valueOf()-created.valueOf();

      if(offset===0) {
        //perform data import here;
        var data = file.getBlob().getDataAsString();

        //ignore empty files;
        if(data!=='') { 
          //split data in rows;
          var arr = data.split('\r\n');

          //resplit array if only one row;
          if(arr.length===1) {
            arr = data.split('\n');
          }

          //append rows with data to sheet;
          arr.forEach(function(el){
            el = el.split(';');
            sh.appendRow(el);
          });
        }          
      }

    }

  }else {
    //if never waited, set minute to wait, else add minute;
    if(!alreadyWaited) {
      alreadyWaited = 60000;
    }else {
      alreadyWaited += alreadyWaited;
    }

    //if waited for 10 minutes -> end recursion;
    if(alreadyWaited===600000) {
      Logger.log('Waited 10 minutes but recieved no files!');
      return;
    }

    //wait a minute and recheck;
    Utilities.sleep(60000);
    return checkFiles(alreadyWaited);
  }      
}

这应该发生：

将新的（最新）.csv文件自动导入到现有的Google电子表格中
