Where is the error in the Google Script code for export to txt?

Question

Google Apps Script

Hello,
There is a table

Task: export through (starting from 1) a column (starting from line 3) to a txt file (take the name from the first line). For this I wrote a script

function export() {
  var Folder = DriveApp.getFolderById("ID");
  var SpreadSheets = SpreadsheetApp.openById('ID').getSheetByName('Минуса');
  
  var values = SpreadSheets.getRange("A3:A").getValues();
  var txtName = SpreadSheets.getRange("A1").getValues();
  var text = values.map(function (a) {return a.join('\t');}).join('\r\n');
  var Files = Folder.getFiles();
  while(Files.hasNext()){
  var File = Files.next();
    if(File.getName() === txtName + ".txt"){
      Folder.removeFile(File);
    }
    }
  Folder.createFile(txtName + '.txt', text);

The problem arises if there are a lot of columns (the script becomes very long) and I tried to write in the form of a loop

function export() {
  var Folder = DriveApp.getFolderById("ID");
  var Files = Folder.getFiles();
  var SpreadSheets = SpreadsheetApp.openById('ID').getSheetByName('Минуса');
  var lastRow = SpreadSheets.getLastRow();
  var c =1;
  for(var i = 3; i<=lastRow;i++){
    for(;c<=15;c+2){
    var values = SpreadSheets.getRange(i, c).getValue();
    var text = values.map(function (a) {return a.join('\t');}).join('\r\n');}
      for(;c>15;c+2){var txtName = SpreadSheets.getRange(1, c).getValues();}
     while(Files.hasNext()){
  var File = Files.next();
    if(File.getName() === txtName + ".txt"){
      Folder.removeFile(File);}
     }
    Folder.createFile(txtName + '.txt', text);
    }
}

TypeError: Cannot find map function on avamys object

Please help me write this script correctly.

But I wouldn't do that. The disk is a complex ecosystem of sensors and triggers. Perhaps you could dig a little deeper and understand the zen of the event model, maybe something will work more smoothly and smoothly, and really online.
