遍历文件夹中的所有电子表格并使用此代码进行编辑？

Question

I am looking to loop the code provided through all of the spreadsheets in a given folder. I'm just not sure how to do it. Every way I try to iterate through the folder errors out. I have tried like 10 different variations.

I am going to use a stand alone script that I can insert the ID number of the folder. Any ideas? Thanks so much for any help you can give. I'm still learning, but getting better. :) Brandon

 function dataUpdate() { var ss = SpreadsheetApp.getActiveSpreadsheet(); // Trying to iterate through all spreadsheets in a folder rather than using .getactivespreadsheet(). var sheet = ss.getSheets()[0]; var cell = sheet.getRange(2,7); var sheets = ss.getSheets()[3]; var cell1 = sheets.getRange(7,8); var cell2 = sheets.getRange(7,9); cell.setValue('RTI') sheets.setName("RTI Data"); sheets.getRange(4, 8).setValue('Cell Value'); sheets.getRange(5, 8).setValue('1'); sheets.getRange(6, 8).setValue('2'); sheets.getRange(7, 8).setValue('3'); sheets.getRange(5, 9).setValue('Tier 1'); sheets.getRange(6, 9).setValue('Tier 2'); sheets.getRange(7, 9).setValue('Tier 3'); cell1.setHorizontalAlignment("center").setBackground("#f0f0f0"); cell2.setHorizontalAlignment("center").setBackground("#f0f0f0"); }

Look for getFolderById() or getFoldersByName(), plus SpreadsheetApp.openById(), you'll figure it out pretty easily.

Edit: Made a stub:

// Iterates trough all files in given folder and logs the A1 in the first sheet in all of them
var folderId = "sdoijawodkhqoud98y12eh";
var folder = DriveApp.getFolderById(folderId);
var files = folders.getFiles();
while (files .hasNext()) {
  var file = files.next(),
      ss = SpreadsheetApp.openById(file.getId()),
      sheet = ss.getSheets()[0],
      A1Value = sheet.getRange("A1").getValue();
  Logger.log(A1Value);
}

Also, try to work with more than a range at a time, don't do a lot of setValue() and getValue(), instead work with array, I would treat it as such:

sheetRange = ss.getRange(1, 1, 7, 9); 
sheetVals = sheetRange.getValues();
sheetVals[ 1 ][ 6 ] = "RTI"
sheetVals[ 3 ][ 7 ] = "Cell Value"

// ... and so on...

sheetRange.setValues(sheetVals);
sheets.getRange(7, 8, 1, 2).setHorizontalAlignment("center").setBackground("#f0f0f0");
