Google Apps 脚本在 Excel 到 Google 工作表之间自动复制工作表

Question

我是编码游戏的新手，每天都在学习如何编码。最近我迷上了 Google App Script，学习制作一个简单的数据库。我尝试对脚本进行解码和重新编码，但就是无法正常工作。它应该转换和替换现有的 google sheet 而不是脚本只是将 excel 转换并复制到 sheet 的许多版本（1,2,3）原始 excel 文件。

// Convert the user's stored excel files to google spreadsheets based on the specified directories.
// There are quota limits on the maximum conversions per day: consumer @gmail = 250.
function convertCollection1() 
{
  var user = Session.getActiveUser(); // Used for ownership testing.
  var origin = DriveApp.getFolderById("1dPsDfoqMQLCokZK4RN0C0VRzaRATr9AN");
  var dest = DriveApp.getFolderById("1M6lDfc_xEkR4w61pUOG4P5AXmSGF1hGy");

  // Index the filenames of owned Google Sheets files as object keys (which are hashed).
  // This avoids needing to search and do multiple string comparisons.
  // It takes around 100-200 ms per iteration to advance the iterator, check if the file
  // should be cached, and insert the key-value pair. Depending on the magnitude of
  // the task, this may need to be done separately, and loaded from a storage device instead.
  // Note that there are quota limits on queries per second - 1000 per 100 sec:
  // If the sequence is too large and the loop too fast, Utilities.sleep() usage will be needed.
  var gsi = dest.getFilesByType(MimeType.GOOGLE_SHEETS), gsNames = {};
  while (gsi.hasNext())
  {
    var file = gsi.next();
    if(file.getOwner().getEmail() == user.getEmail())
      gsNames[file.getName()] = true;
  }

  // Find and convert any unconverted .xls, .xlsx files in the given directories.
  var exceltypes = [MimeType.MICROSOFT_EXCEL, MimeType.MICROSOFT_EXCEL_LEGACY];
  for(var mt = 0; mt < exceltypes.length; ++mt)
  {
    var efi = origin.getFilesByType(exceltypes[mt]);
    while (efi.hasNext())
    {
      var file = efi.next();
      // Perform conversions only for owned files that don't have owned gs equivalents.
      // If an excel file does not have gs file with the same name, gsNames[ ... ] will be undefined, and !undefined -> true
      // If an excel file does have a gs file with the same name, gsNames[ ... ] will be true, and !true -> false
      if(file.getOwner().getEmail() == user.getEmail() && !gsNames[file.getName()]
      {
        Drive.Files.insert (
          {title: file.getName(), parents: [{"id": dest.getId()}]},
          file.getBlob(),
          {convert: true}
        );
        // Do not convert any more spreadsheets with this same name.
        gsNames[file.getName()] = true;
      }
    }
  }
}

脚本的逻辑是正确的。但是，您使用的函数 .getName() 和 Drive.Files.insert 中存在细微的问题，导致代码中出现意外行为。

folder.getName() 获取文件的全名，其中包括 .xls/.xlsx 扩展名。但是，当您使用 Drive.Files.insert 转换这些文件时，扩展名将被删除。因此，您的 gsNames 对象的文件名没有扩展名，但是当代码尝试使用具有文件扩展名的 !gsNames[file.getName()] 访问特定元素时。它总是 returns undefined，被评估为 True。

因此，在尝试检查同一文件是否已被转换之前，您需要删除文件扩展名。用于删除文件扩展名的正则表达式是从 here 无耻地复制的。您的逻辑将修改为：

if(file.getOwner().getEmail() == user.getEmail() && !gsNames[file.getName().replace(/\.[^/.]+$/, "")])

您的文件代码将是：

function convertCollection1() 
{
  var user = Session.getActiveUser(); // Used for ownership testing.1aJcbdGhwliTs_CZ-3ZUvQmGRDzBM7fv9
  var origin = DriveApp.getFolderById("1dPsDfoqMQLCokZK4RN0C0VRzaRATr9AN");
  var dest = DriveApp.getFolderById("1M6lDfc_xEkR4w61pUOG4P5AXmSGF1hGy");

  // Index the filenames of owned Google Sheets files as object keys (which are hashed).
  // This avoids needing to search and do multiple string comparisons.
  // It takes around 100-200 ms per iteration to advance the iterator, check if the file
  // should be cached, and insert the key-value pair. Depending on the magnitude of
  // the task, this may need to be done separately, and loaded from a storage device instead.
  // Note that there are quota limits on queries per second - 1000 per 100 sec:
  // If the sequence is too large and the loop too fast, Utilities.sleep() usage will be needed.
  var gsi = dest.getFilesByType(MimeType.GOOGLE_SHEETS), gsNames = {};
  while (gsi.hasNext())
  {
    var file = gsi.next();
    if(file.getOwner().getEmail() == user.getEmail())
      gsNames[file.getName()] = true;

    Logger.log(JSON.stringify(gsNames))
  }

  // Find and convert any unconverted .xls, .xlsx files in the given directories.
  var exceltypes = [MimeType.MICROSOFT_EXCEL, MimeType.MICROSOFT_EXCEL_LEGACY];
  for(var mt = 0; mt < exceltypes.length; ++mt)
  {
    var efi = origin.getFilesByType(exceltypes[mt]);
    while (efi.hasNext())
    {
      var file = efi.next();
      // Perform conversions only for owned files that don't have owned gs equivalents.
      // If an excel file does not have gs file with the same name, gsNames[ ... ] will be undefined, and !undefined -> true
      // If an excel file does have a gs file with the same name, gsNames[ ... ] will be true, and !true -> false
      if(file.getOwner().getEmail() == user.getEmail() && !gsNames[file.getName().replace(/\.[^/.]+$/, "")])
      {
        Drive.Files.insert (
          {title: file.getName(), parents: [{"id": dest.getId()}]},
          file.getBlob(),
          {convert: true}
        );
        // Do not convert any more spreadsheets with this same name.
        gsNames[file.getName()] = true;
      }
    }
  }
  Logger.log(JSON.stringify(gsNames))
}

注意 Logger.log() 的用法，将来使用它来确定程序可能正在访问什么以及您认为它正在做什么。

干杯！
