将电子表格范围另存为CSV文件功能

Question

我正在处理GAS（谷歌APP脚本）中的代码，而且我已经在我的头上了。

这个附加到Google文档电子表格的代码应该从不同的标签中获取范围的集合，并将它们的值复制到新的CSV文件中。我已经整理了一个看起来很实用的脚本（基于我对GAS的有限经验）但是当我运行它时我得到了这个错误：

  

无法从此上下文调用DocumentApp.getUi（）。

虽然我确定它充满了其他错误，但我不知道如何妥善解决。

这是我得到的：

// Function will run upon clicking assigned drawing object in spreadsheet
function exportData() {

  // Prompts the user for the file name
  var ui = DocumentApp.getUi();
  var fileName = ui.prompt(
   'Export Project Data',
    'Save input values to new file?\n\nFile Name:',
   ui.ButtonSet.OK_CANCEL);

  // if user clicks 'yes' to save
  if (response.getSelectedButton() == ui.Button.YES) {

    // 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 using the function defined below
      var csvFile = convertRangeToCsvFile_(fileName);

      // Create a file in the Docs List with the given name and the CSV data
      DriveApp.createFile(fileName, csvFile);
      }

    // If given file name is empty display message
    else {
      Browser.msgBox("Error: Please enter a CSV file name.");
    }
  }

  // if user clicks 'no' to exit
  if (response.getSelectedButton() == ui.Button.NO) {}
}



// Function will run when called upon by another function
function convertRangeToCsvFile_(csvFileName) {

  // Define all the input ranges from the spreadsheet
