How to send a email with a PDF file attachment based on a condition using Google App Script

I solved the following problem. Send PDF files to everyone using the Google Script service of Google Sheets. I tried sending one file to everyone on the list. It went well.
However, I’ve run into a problem trying to make a similar Script, but for sending multiple files to different people on a Google Sheet list.Each person has different files.

For example:
John has three PDF files: John_ 999901.pdf, John_ 999902.pdf, and John_999903.pdf.
David has two PDF files: David_ 999901.pdf and David_99990.
Jun has two PDF files: Jun_999901.pdf and Jun_999902.pdf.
And finally, Michel has only one PDF file: Michel_999901.pdf.
All PDF files are saved on GOOGLE DRIVE.
This is where I save the PDF file
This is my spreadsheet
Is there a way to send an email based on the file name that corresponds to the person of the same name in the list?
Below is the code that I tried to send the file

function onOpen() 
  var ui = SpreadsheetApp.getUi();
      .addItem('送信', 'sendFormToAll')
function include(filename) {
  return HtmlService.createHtmlOutputFromFile(filename).getContent();
function sendFormToAll()
   var sheet = SpreadsheetApp.getActive().getSheetByName('Sheet1');
   var last_row = sheet.getDataRange().getLastRow();
   for(var row=2; row <= last_row; row++)

function sendPDFForm()
  var row = SpreadsheetApp.getActiveSheet().getActiveCell().getRow();

function sendEmailWithAttachment(row)
  var filename= '?????.pdf';// I don't know what to do at this point
  var file = DriveApp.getFilesByName(filename);
  if (!file.hasNext()) 
    console.error("Could not open file "+filename);
  var client = getClientInfo(row);
  var template = HtmlService
  template.client = client;
  var message = template.evaluate().getContent();
    subject: "Send File",
    htmlBody: message ,
    attachments: []


function getClientInfo(row)
   var sheet = SpreadsheetApp.getActive().getSheetByName('Sheet1');
   var values = sheet.getRange(row,1,row,8).getValues();
   var rec = values[0];
  var client = 
        email: rec[1]
      }; =;
  return client;

In your script, how about the following modification for achieving your goal?

Modification points:

  • When getValue is used in a loop, the process cost becomes high.
  • It is requried to add the logic for searching the filename from the files in the folder.
  • When I saw your sample Spreadsheet, Situation is the column “C”. But when I saw your script, it’s sheet.getRange(row,8).setValue("send");. If Situation is the same with sheet.getRange(row,8).setValue("send");, it is requried to be sheet.getRange(row,3).setValue("send");. But I’m not sure about your actual situation. So in this modification, I used sheet.getRange(row,3).setValue("send"); for your sample Spreadsheet.
  • In your script, Sheet1 is used as the sheet name. But in your sample Spreadsheet, the sheet name is Request. In this modification, I used Request for your sample Spreadsheet.

When these points are reflected to your script, it becomes as follows.

Modified script:

Please set your folder ID to ### of DriveApp.getFolderById("###").searchFiles(`title contains '${name}' and trashed=false`);.

function sendFormToAll() {
  var sheet = SpreadsheetApp.getActive().getSheetByName('Request');
  var values = sheet.getRange("A2:C" + sheet.getLastRow()).getValues();
  var rangeList = values.reduce((ar, e, i) => {
    if (e[2] == "Send File") return ar;
    var [name, email] = => f.trim());
    var files = DriveApp.getFolderById("###").searchFiles(`title contains '${name}' and trashed=false`);
    var attachments = [];
    var r = new RegExp(`^${name}[_\d\s]+\.pdf$`, "i");
    while (files.hasNext()) {
      var file =;
      if (r.test(file.getName())) attachments.push(file.getBlob());
    if (attachments.length == 0) {
      console.error("Could not find files related to " + name);
      return ar;
    var template = HtmlService.createTemplateFromFile('index');
    template.client = { name };
    var message = template.evaluate().getContent();
    MailApp.sendEmail({ to: email, subject: "Send File", htmlBody: message, attachments });
    ar.push(`C${i + 2}`);
    return ar;
  }, []);
  if (rangeList.length == 0) return;
  sheet.getRangeList(rangeList).setValue("Send File");
