Add filename to the first column of the import

I have files on the folder and i import them to the google sheet.
I need to add filename to first column before import, but my script add it only to first cell before import
So it gives me:
Filename
Pencil
01/01/2022
Pen
01/02/2022
Hat
And i need
Filename
1/01/2022
Pencil
Filename
1/01/2022
Pen
Filename
01/02/2022
Hat
function Import_Kredo() {
var arr = [];
var files = DriveApp.getFolderById("13kymSiqX0-L6a9ev4It1_BEjH-xM8rnc").getFiles();
var ss = SpreadsheetApp.getActiveSpreadsheet();
var copySheet = ss.getSheetByName("Table 1");
copySheet.getRange('A2:G').clear();
while (files.hasNext()) {
var file = files.next();
var mimeType = file.getMimeType();
var ss1 = null, id = null;
if (mimeType == MimeType.MICROSOFT_EXCEL) {
id = Drive.Files.copy({ mimeType: MimeType.GOOGLE_SHEETS }, file.getId()).id;
ss1 = SpreadsheetApp.openById(id);
} else if (mimeType == MimeType.GOOGLE_SHEETS) {
ss1 = SpreadsheetApp.open(file);
}
if (!ss1) continue;
var sheet = ss1.getSheetByName("Table 1");
if (!sheet) continue;
var sheetsRange = sheet.getDataRange();
var sheetsValues = sheetsRange.getValues().filter(r => r[1]).filter(e => e);
var v = sheetsValues.slice(1);
console.log([file.getName(), v])
arr = arr.concat([[file.getName(), ...Array(v[0].length - 1).fill(null)], ...v]);
if (id) DriveApp.getFileById(id).setTrashed(true); // or Drive.Files.remove(id);
}
copySheet.getRange(5, 1, arr.length, arr[0].length).setValues(arr);
}

In your situation, how about the following modification?
From:
arr = arr.concat([[file.getName(), ...Array(v[0].length - 1).fill(null)], ...v]);
To:
var filename = file.getName();
arr = arr.concat(v.map(e => [filename, ...e]));
By this modification, the filename is put into the 1st column of each row.

Function B returns null when called from function A, but returns correct value when logged within function B

please refer to the code below:
function getGdriveLinks() {
const ss = SpreadsheetApp.getActiveSpreadsheet();
const sheet = ss.getSheetByName('Test');
const fileNames = sheet.getRange('C2:C').getValues();
const mainFolder = DriveApp.getFolderById('Folder ID');
for (var i = 0; i < fileNames.filter(String).length; i++){
var fileName = fileNames[i][0].toString();
var fileLink = getGdriveLink(fileName,mainFolder);
Logger.log(fileLink);
}
}
function getGdriveLink(searchFileName,folder){
var mainFiles = folder.getFiles();
while (mainFiles.hasNext()){
var file = mainFiles.next();
if(file.getName().indexOf(searchFileName) != -1){
Logger.log(file.getUrl());
return file.getUrl();
}
}
var subFolders = folder.getFolders();
while (subFolders.hasNext()){
var subFolder = subFolders.next();
getGdriveLink(searchFileName,subFolder);
}
}
Basically, the aim is to get the filenames in C2:C of Test sheet, find each of these in the 'Folder ID', and then return their URL. The URL is returned correctly when I log it from getGdriveLink(searchFileName,folder) using Logger.log(file.getUrl()). However, it returns null via the Logger.log(fileLink) when the result goes back to getGdriveLinks() function. Is there anything I'm missing? We're using a corporate domain if that's something to consider. Hoping for your guidance. Thanks!

You could also do it this way and avoid recursion altogether
function getPathAllDrivesFromId(fileid) {
var ids = [{id:fileid,name:DriveApp.getFileById(fileid).getName()}];
let r;
do {
r = Drive.Files.get(fileid,{supportsAllDrives:true,supportsTeamDrives:true});
if(r.parents.length > 0) {
//Logger.log(JSON.stringify(r.parents[0]));
ids.push({id:r.parents[0].id,name:DriveApp.getFolderById(r.parents[0].id).getName()});
fileid = r.parents[0].id
}
}while (r.parents.length > 0);
if(ids[ids.length - 1].name == "Drive") {
ids[ids.length - 1].name = Drive.Drives.get(ids[ids.length - 1].id).name;
}
//Logger.log(JSON.stringify(ids));
let path = ids.map(obj => obj.name).flat().reverse().join(' / ')
//Logger.log(path);
return path;
}
function getGdriveLinks() {
const ss = SpreadsheetApp.getActive();
const sh = ss.getSheetByName('Test');
const osh = ss.getSheetByName("Results");
const ns = sh.getRange('C2:C' + sh.getLastRow()).getValues();
const folder = DriveApp.getFolderById('Folder ID');
const result = [["Filename", "Id", "Url", "path"]];
ns.forEach(n => {
let files = DriveApp.getFilesByName(n);
while (files.hasNext()) {
let file = files.next();
let path = getPathAllDrivesFromId(file.getId());
if (~path.indexOf(folder.getName())) {
result.push([file.getName(), file.getId(), file.getUrl(), path]);
}
}
})
osh.clearContents();
osh.getRange(1, 1, result.length, result[0].length).setValues(result);
}

Google script - Service error: Spreadsheets

As of a couple of weeks now, I'm getting a "Service error: Spreadsheets" error when running a script in Google Sheets. Before that, it was working fine.
It's supposed to export a PDF while deleting some of the empty rows.
I tried adding a 1000ms delay, but that didn't work.
Any help would be greatly appreciated. You can find the code below.
var sheetName = "PDF - B";
var sheetName2 = "Offertes";
var folderID = "XXX"; // Folder id to save in a folder.

I have also noticed "Service error: Spreadsheets" when trying to create a pdf; this started occurring sometime between 7 April and 28 April.
I have narrowed it down to to a column in my spreadsheet which contains images using the =IMAGE() function. If these are copied using Range.setValues() the "Service error" occurs. This in itself seems to me to be a bug as it's not very informative about what's wrong. It's arguable whether the =IMAGE() should be copyable using setValues()
However, I've discovered it is possible to copy the image formula using Range.setFormulas(), and it's also possible to use Range.setValues() on an image created using menu>insert>image but setValues() does not work if the image is created from a script using SpreadsheetApp.newCellImage()
The last mentioned problem means there is no bypass for scripts to avoid "Service error: spreadsheets" for scripts without some fiddly recoding.
Here's a shared spreadsheet which illustrates the problem: https://docs.google.com/spreadsheets/d/1xJoOf0DJBRUTbaskjKsly3pAGNJ72sT_EV8Tn246Ufo/edit?usp=sharing
"Service error" is also reported on the google issuetracker

Based on the comment of #Tyler2P, I created a workaround, replacing the part from //repace cell values with text with the following code:
var destSheet = destSpreadsheet.getSheets()[0];
var destSheet = destSpreadsheet.getSheetByName(sheetName);
var sourceRange = sourceSheet.getRange(1,1,sourceSheet.getMaxRows(),sourceSheet.getMaxColumns());
var sourceRange1 = sourceSheet.getRange(1,1,3,sourceSheet.getMaxColumns());
var sourceRange2 = sourceSheet.getRange(7,1,(sourceSheet.getMaxRows()-7),sourceSheet.getMaxColumns());
var sourcevalues = sourceRange.getValues();
var sourcevalues1 = sourceRange1.getValues();
var sourcevalues2 = sourceRange2.getValues();
var destRange = destSheet.getRange(1, 1, destSheet.getMaxRows(), destSheet.getMaxColumns());
var destRange1 = destSheet.getRange(1,1,3,sourceSheet.getMaxColumns());
var destRange2 = destSheet.getRange(7,1,(sourceSheet.getMaxRows()-7),sourceSheet.getMaxColumns());
destRange1.setValues(sourcevalues1);
destRange2.setValues(sourcevalues2);

Script to Transfer Column Values to 1 of 4 Columns Based on Empty Columns

I'm trying to figure out a script to automate the transfer of data from a column on one sheet, to one of four columns on another sheet. The data being transferred is an order that has been placed, so the data needs to stay in the column its transferred to until it is received. So basically the script needs to find the next blank column and transfer the data there.
For reference, the sheet is HERE:https://docs.google.com/spreadsheets/d/1DxafMMZL7Nc2M4A41Dzssf9dgrzYZgsX1qKgtfhLMlM/edit?usp=sharing. The data that will be transferred is Ordering!P5:P, and will be transferred from there to Pending TOs, either E6:E, F6:F, G6:G or H6:H, based on whether the previous column already has values.
I wrote the following script, but it only worked on the initial test, and fails to detect empty columns F:H. After clearing column E, I could not repeat the initial success.
Any guidance is greatly appreciated.
function PasteTOTEST() {
var ss = SpreadsheetApp.getActive();
const ui = SpreadsheetApp.getUi();
const response = ui.alert('Table is full', ui.ButtonSet.OK);
var copyFrom = ss.getRange('Ordering!P5:P');
var copyTo = ss.setActiveSheet(ss.getSheetByName('Pending TOs'));
var toColumnA = copyTo.getRange('E6:E').activate();
var toColumnB = copyTo.getRange('F6:F').activate();
var toColumnC = copyTo.getRange('G6:G').activate();
var toColumnD = copyTo.getRange('H6:H').activate();
if(ISBLANK(toColumnA)) {
toColumnA;
copyFrom.copyTo(ss.getActiveRange(), SpreadsheetApp.CopyPasteType.PASTE_VALUES, false);
}
else if(ISBLANK(toColumnB)) {
toColumnB;
copyFrom.copyTo(ss.getActiveRange(), SpreadsheetApp.CopyPasteType.PASTE_VALUES, false);
}
else if(ISBLANK(toColumnC)) {
toColumnC;
copyFrom.copyTo(ss.getActiveRange(), SpreadsheetApp.CopyPasteType.PASTE_VALUES, false);
}
else if(ISBLANK(toColumnD)) {
toColumnD;
copyFrom.copyTo(ss.getActiveRange(), SpreadsheetApp.CopyPasteType.PASTE_VALUES, false);
}
}

This function will paste the data in the first available column in ranges E6:E, F6:F, G6:G or H6:H
function PasteTOTEST() {
var ss = SpreadsheetApp.getActive();
const ui = SpreadsheetApp.getUi();
const fsh = ss.getSheetByName('Ordering');
const tsh = ss.getSheetByName('Pending TOs');
let frg = fsh.getRange(5, 16, getColHite(16, fsh, ss) - 4, 1);
let ar = availableRanges();
if(ar && ar.length) {
trg = tsh.getRange(6, ar[0]);
frg.copyTo(trg, SpreadsheetApp.CopyPasteType.PASTE_VALUES, false);
} else {
ui.alert('Table is full', ui.ButtonSet.OK);
}
}
function getColHite(col, sh, ss) {
var ss = ss || SpreadsheetApp.getActive();
var sh = sh || ss.getActiveSheet();
var col = col || sh.getActiveCell().getColumn();
var rcA = [];
if (sh.getLastRow()) { rcA = sh.getRange(1, col, sh.getLastRow(), 1).getValues().flat().reverse(); }
let s = 0;
for (let i = 0; i < rcA.length; i++) {
if (rcA[i].toString().length == 0) {
s++;
} else {
break;
}
}
return rcA.length - s;
}
function clearAllRanges() {
const ss = SpreadsheetApp.getActive();
const sh = ss.getSheetByName('Pending TOs');
[...Array.from(Array(4).keys(), x => x + 5)].forEach(n => {
let h = getColHite(n, sh, ss)
if(h>4)sh.getRange(5, n, h - 4, 1).clearContent()
});
}
function availableRanges() {
const ss = SpreadsheetApp.getActive();
const sh = ss.getSheetByName('Pending TOs');
let r = [...Array.from(Array(4).keys(), x => x + 5)].reduce((a,v,arr) => {
let h = getColHite(v, sh, ss);
if(h < 6) a.r.push(v);
return a;
},{r:[],availableRanges:function(){return this.r;}}).availableRanges();
//Logger.log(r);
return r;
}
Demo:
In case you are wondering what this does:
[...Array.from(Array(4).keys(), x => x + 5)]
It just feeds the four column numbers into the reduce loop current value

How to add a color stripe to every last row of a student attendance sheet using Google App Scripts?

As part of a student attendance system, I would like to add a color stripe to every last row of a class for attendance using App Scripts. My columns of Google Sheets are: (i) Date, (ii) Email, (iii) Latitude, (iv) Longitude, and (v) Subject-code. Tried many ways but did not find the solution.

//MailApp.sendEmail(students[i][0].toString(), subject ,body, {from: from, attachments:[{fileName:"YourAttendaceRecord.xlsx", content:contents, mimeType:"MICROSOFT_EXCEL"}]});
}
}

Explanation:
Based on your question, I understand the following steps:
Check if you have at least two unique subjects in column E. One way to do that is to find the unique list of subjects. If the length of that list is 2 or more it means that you have different subjects. In that case, the first block of the if statement evaluates to true and you add a yellow line in the row before the subject is changed.
If you have only one subject, namely the length of the unique list of subjects is 1 the first block of the if statement will evaluate to false. In that case, the script will check whether column A has 2 or more unique dates. If it does, the second block of the if statement will be executed and the script will add a yellow line in the row before the date is changed. Otherwise, it won't do anything.
Solution:
You can execute color() as a standalone script. I would advice you to save this function in a new .gs file and then simply call it within your current script. Namely, put color() anywhere you want in the code snippet you provided.
function color() {
const sss = SpreadsheetApp.getActiveSpreadsheet();
const sheet = sss.getSheetByName("TempDataSet");
const subs = sheet.getRange('E2:E'+sheet.getLastRow()).getValues().flat();
const usubs = subs.filter((value, index, self)=>self.indexOf(value) === index);
const dts = sheet.getRange('A2:A'+sheet.getLastRow()).getDisplayValues().flat();
const udts = dts.filter((value, index, self)=>self.indexOf(value) === index);
if(usubs.length>1){
subs.forEach((s,i)=>{
if(i>1){
if(subs[i]!=subs[i-1]){
sheet.getRange(i+1,1,1,5).setBackground('yellow');
}}});
}
else if (udts.length>1){
dts.forEach((d,i)=>{
if(i>1){
if(dts[i]!=dts[i-1]){
sheet.getRange(i+1,1,1,5).setBackground('yellow');
}}});
}
}
