谷歌电子表格脚本非常慢

Question

我有一个每天运行的脚本。它非常慢，我无法弄清楚是什么让它变慢了。有人有什么建议吗？我最初写了一个函数来做一张纸，然后我添加了一个函数来循环并在每张纸上调用它。

function addAllLog() {
  var ss        = SpreadsheetApp.getActiveSpreadsheet();
  var allSheets = ss.getSheets();
  // build array of all sheets
  for (var i in allSheets) { 
    if (i == 0) { continue;}  // skip first sheet

    var tmpName = allSheets[i].getName();
    if (tmpName == "Print Sheet")  break;  //stop at this tab

    var tmpName = ss.getSheetByName(allSheets[i].getName());
    ss.setActiveSheet(ss.getSheetByName(allSheets[i].getName()));

    addLog();
  }
}

function addLog () {
    var sheet = SpreadsheetApp.getActiveSheet();
    var numLastRow = sheet.getLastRow();
    var numThisRow = numLastRow+1;
    today = new Date();
    today.setDate(today.getDate()-1);
    today = Utilities.formatDate(today,"EDT","MM/DD/YYYY");

    if (sheet.getMaxRows() == numLastRow) sheet.insertRowAfter(numLastRow);

    var range = sheet.getRange(numLastRow,2,1,16); // last row, column b, 1 row of 16 columns
    var data = range.getValues();

    range.copyTo(sheet.getRange(numLastRow+1, 2,1,16)); //you will need to define the size of the copied data see getRange()

    sheet.getRange(numThisRow, 1).setValue(today);
    sheet.getRange(numThisRow, 4).setValue('Log');
    sheet.getRange(numThisRow, 5).setValue('');  //erase copied value if there was anything there
    sheet.getRange(numThisRow, 7).setValue('');  //erase copied value if there was anything there

    sheet.getRange(numThisRow, 6).setValue('=GoogleFinance(C' + numThisRow + ',"price")');
    sheet.getRange(numThisRow, 6).setValues(sheet.getRange(numThisRow,6).getValues());

}

任何关于加快速度的建议将不胜感激！

Answer 1

每次直接在电子表格上设置一个范围内的值时，至少需要 800 毫秒，因此解决此问题的最佳方法是使用这些值创建一个 Object[][] 并使用 sheet.getRange(range).setValues(Object[][]) 进行设置，确保Object[][] 具有与range 相同的宽高。

在这篇 Best Practices | Apps Script 的帖子中，Google 解释了其中的区别。

另外，一个有趣的解决方案是创建一个Spreadsheet abstraction in memory。我基于这种方法制作了自己的MemsheetApp，效果非常好。如果你想改进它，我会收到拉取请求。

此版本不需要您激活每张工作表，因此可能需要更少的时间。

function addAllLog() {
  var ss=SpreadsheetApp.getActive();
  var allSheets = ss.getSheets();
  for (var i=1;i<allSheets.length;i++){ 
    var shtname = allSheets[i].getName();
    if (shtname == "Print Sheet"){
      break;  //stop at this tab
    }else{
      addLog(shtname);
    }
  }
}

function addLog (shtname) {
  var sheet = SpreadsheetApp.getSheetByName(shtname);
  var numLastRow = sheet.getLastRow();
  var numThisRow = numLastRow+1;
  today = new Date();
  today.setDate(today.getDate()-1);
  today = Utilities.formatDate(today,"EDT","MM/DD/YYYY");
  if (sheet.getMaxRows() == numLastRow) sheet.insertRowAfter(numLastRow);
  var range = sheet.getRange(numLastRow,2,1,16); 
  range.copyTo(sheet.getRange(numLastRow+1, 2,1,16)); 
  sheet.getRange(numThisRow, 1).setValue(today);
  sheet.getRange(numThisRow, 4).setValue('Log');
  sheet.getRange(numThisRow, 5).setValue('');
  sheet.getRange(numThisRow, 7).setValue('');
  sheet.getRange(numThisRow, 6).setFormula('=GoogleFinance(C' + numThisRow + ',"price")');
}
