Это быстрее, но на самом деле самый большой фрагмент времени, вероятно, просто открывает файлы.
function faster() {
var ss=SpreadsheetApp.getActive();
var folder=DriveApp.getFolderById();
var files=folder.getFilesByType(MimeType.GOOGLE_SHEETS);
while (files.hasNext()) {
var file=files.next();
var tss=SpreadsheetApp.openById(file.getId());
var vA=tss.getSheetByName('Form').getRange(1,1,22,8).getValues();
var ssh=ss.getSheetByName("Order Status")
ssh.insertRowAfter(1);//you could avoid this by creating a sheet that you could append to and that would be a little faster
SpreadsheetApp.flush();//not sure if this is needed but this has to complete before the next operation takes place
ssh.getRange(2,1,1,5).setValues([[vA[0][2],vA[2][2],vA[0][7],vA[21][2],vA[17][0]]]);
}
}
