如何使用Google Apps腳本自動下載Google電子表格數據

Question

我是使用Google Apps腳本的新手。我想知道是否可以創建一個備份程序，在每次更改15分鐘後自動將電子表格數據下載到csv文件中。 我是否必須創建某種cronjob？ 我已經創建了一個從當前工作表中讀取所有數據並創建一個csv文件的腳本。

/** 
* Adds a custom menu to the active spreadsheet, containing a single menu item 
* for invoking the readRows() function specified above. 
* The onOpen() function, when defined, is automatically invoked whenever the 
* spreadsheet is opened. 
* For more information on using the Spreadsheet API, see 
* https://developers.google.com/apps-script/service_spreadsheet 
*/ 
function onOpen() { 
    var sheet = SpreadsheetApp.getActiveSpreadsheet(); 
    var entries = [{ 
    name : "Download Data", 
    functionName : "saveAsCSV" 
    }]; 
    sheet.addMenu("Script Center Menu", entries); 
}; 

function saveAsCSV() { 
    // Prompts the user for the file name 
    var fileName = Browser.inputBox("Save CSV file as (e.g. myCSVFile):"); 

    // Check that the file name entered wasn't empty 
    if (fileName.length !== 0) { 
    // Add the ".csv" extension to the file name 
    fileName = fileName + ".csv"; 
    // Convert the range data to CSV format 
    var csvFile = convertRangeToCsvFile_(fileName); 
    // Create a file in the Docs List with the given name and the CSV data 
    DocsList.createFile(fileName, csvFile); 
    } 
    else { 
    Browser.msgBox("Error: Please enter a CSV file name."); 
    } 
} 

function convertRangeToCsvFile_(csvFileName) { 
    try { 
    var csvFile = undefined; 

    var sheet = SpreadsheetApp.getActiveSheet(); 
    var rows = sheet.getDataRange(); 
    var numRows = rows.getNumRows(); 
    var data = rows.getValues(); 

    // Loop through the data in the range and build a string with the CSV data 
    if (data.length > 1) { 
     var csv = ""; 
     for (var row = 0; row < data.length; row++) { 
     for (var col = 0; col < data[row].length; col++) { 
      if (data[row][col].toString().indexOf(",") != -1) { 
      data[row][col] = "\"" + data[row][col] + "\""; 
      } 
     } 

     // Join each row's columns 
     // Add a carriage return to end of each row, except for the last one 
     if (row < data.length-1) { 
      csv += data[row].join(",") + "\r\n"; 
     } 
     else { 
      csv += data[row]; 
     } 
     } 
     csvFile = csv; 
    } 
    return csvFile; 
    } 
    catch(err) { 
    Logger.log(err); 
    Browser.msgBox(err); 
    } 
} 

我想定期運行此腳本。我必須爲此做些什麼？

代碼將會相同。只需在電子表格中添加一個觸發器即可。 只需進入腳本編輯器 - >資源 - >所有觸發器 並添加一個新的觸發器，使其具有時間驅動性，並選擇時間間隔並完成。 :)

function saveAsCSV() { 
    // Prompts the user for the file name 
    var fileName = SpreadsheetApp.getActiveSheet().getSheetName(); 

    // Check that the file name entered wasn't empty 
    if (fileName.length !== 0) { 
    // Add the ".csv" extension to the file name 
    fileName = fileName + ".csv"; 

    // Convert the range data to CSV format 
    var csvFile = convertRangeToCsvFile_(fileName); 
    // Create a file in the Docs List with the given name and the CSV data 
    DocsList.createFile(fileName, csvFile); 
    } 
    else { 
    Browser.msgBox("Error: Please enter a CSV file name."); 
    } 
} 

function convertRangeToCsvFile_(csvFileName) { 
    try { 
    var csvFile = undefined; 

    var ss = SpreadsheetApp.getActiveSpreadsheet(); 
    var sheet = ss.getSheets()[10]; 
    var rows = sheet.getDataRange(); 
    var numRows = rows.getNumRows(); 
    var data = rows.getValues(); 

    // Loop through the data in the range and build a string with the CSV data 
    if (data.length > 1) { 
     var csv = ""; 
     for (var row = 0; row < data.length; row++) { 
     for (var col = 0; col < data[row].length; col++) { 
      if (data[row][col].toString().indexOf(",") != -1) { 
      data[row][col] = "\"" + data[row][col] + "\""; 
      } 
     } 

     // Join each row's columns 
     // Add a carriage return to end of each row, except for the last one 
     if (row < data.length-1) { 
      csv += data[row].join(",") + "\r\n"; 
     } 
     else { 
      csv += data[row]; 
     } 
     } 
     csvFile = csv; 
    } 
    return csvFile; 
    } 
    catch(err) { 
    Logger.log(err); 
    Browser.msgBox(err); 
    } 
}
