Autofill formulas in multiple sheets - google-apps-script

Question

I have a problem to address, I have a Gsheet with many sheets that have columns with many formulas, for example I have a sheet AD that in the column A, N, O, P, Q, R, S , T , U, V , W , Y and Z have formulas. I have solved it with the script that I put here but it takes too long.
The thing is that in this Gsheet I have more sheets with as many formulas as the AD sheet, I have a MAIL etc sheet that has formulas in skipped columns, how can I optimize the script so that it copies formulas in the column that has formulas and drags them to the last column with data?
`
function autoFill(){
var spreadsheet = SpreadsheetApp.getActive();
var hojaAD = spreadsheet.getSheetByName('AD');
var copiaA2 = hojaAD.getRange('A2');
var destinationRangeA = hojaAD.getRange(2,1,hojaAD.getLastRow()-1); //el 2 es la fila y el 1 la column
copiaA2.copyTo(destinationRangeA);
var copiaO2 = hojaAD.getRange('O2');
var destinationRangeO = hojaAD.getRange(2,15,hojaAD.getLastRow()-1); //el 2 es la fila y el 1 la column
copiaO2.copyTo(destinationRangeO);
var copiaP2 = hojaAD.getRange('P2');
var destinationRangeP = hojaAD.getRange(2,16,hojaAD.getLastRow()-1); //el 2 es la fila y el 1 la column
copiaP2.copyTo(destinationRangeP);
var copiaQ2 = hojaAD.getRange('Q2');
var destinationRangeQ = hojaAD.getRange(2,17,hojaAD.getLastRow()-1); //el 2 es la fila y el 1 la column
copiaQ2.copyTo(destinationRangeQ);
var copiaR2 = hojaAD.getRange('R2');
var destinationRangeR = hojaAD.getRange(2,18,hojaAD.getLastRow()-1); //el 2 es la fila y el 1 la column
copiaR2.copyTo(destinationRangeR);
var copiaS2 = hojaAD.getRange('S2');
var destinationRangeS = hojaAD.getRange(2,19,hojaAD.getLastRow()-1); //el 2 es la fila y el 1 la column
copiaS2.copyTo(destinationRangeS);
var copiaT2 = hojaAD.getRange('T2');
var destinationRangeT = hojaAD.getRange(2,20,hojaAD.getLastRow()-1); //el 2 es la fila y el 1 la column
copiaT2.copyTo(destinationRangeT);
var copiaU2 = hojaAD.getRange('U2');
var destinationRangeU = hojaAD.getRange(2,21,hojaAD.getLastRow()-1); //el 2 es la fila y el 1 la column
copiaU2.copyTo(destinationRangeU);
var copiaV2 = hojaAD.getRange('V2');
var destinationRangeV = hojaAD.getRange(2,22,hojaAD.getLastRow()-1); //el 2 es la fila y el 1 la column
copiaV2.copyTo(destinationRangeV);
var copiaW2 = hojaAD.getRange('W2');
var destinationRangeW = hojaAD.getRange(2,23,hojaAD.getLastRow()-1); //el 2 es la fila y el 1 la column
copiaW2.copyTo(destinationRangeW);
var copiaY2 = hojaAD.getRange('Y2');
var destinationRangeY = hojaAD.getRange(2,25,hojaAD.getLastRow()-1); //el 2 es la fila y el 1 la column
copiaY2.copyTo(destinationRangeY);
var copiaZ2 = hojaAD.getRange('Z2');
var destinationRangeZ = hojaAD.getRange(2,26,hojaAD.getLastRow()-1); //el 2 es la fila y el 1 la column
copiaZ2.copyTo(destinationRangeZ);

I have tried to make a script but it is slow

Answer 1

Grouping columns as suggested by #GiampaoloFerradini.
Instead of 12 discrete columns, the function applies to three discrete groups:
Column A
Column O-W inclusive
Column Y-Z inclusive
Column X is omitted; just as it is not part of the discrete columns in the OP script.
function autoFill(){
var spreadsheet = SpreadsheetApp.getActive();
var hojaAD = spreadsheet.getSheetByName('AD');
// CopiaA2
var copiaA2 = hojaAD.getRange(2,1)
// Logger.log("DEBUG: copiaA2 is "+copiaA2.getA1Notation())
var copiaA2LR = hojaAD.getLastRow()
// Logger.log("DEBUG: last row = "+copiaA2LR)
var destinationRangeA = hojaAD.getRange(2,1,(copiaA2LR-1),1)
// Logger.log("DEBUG: destination rangeA = "+destinationRangeA.getA1Notation())
copiaA2.copyTo(destinationRangeA)
// CopiaO2-W2
var copiaOW2 = hojaAD.getRange(2,15,1,9)
// Logger.log("DEBUG: copiaOW2 is "+copiaOW2.getA1Notation())
var destinationRangeOW = hojaAD.getRange(2,15,(copiaA2LR-1),9)
// Logger.log("DEBUG: destination rangeOW = "+destinationRangeOW.getA1Notation())
copiaOW2.copyTo(destinationRangeOW)
// CopiaY2-Z2
var copiaYZ2 = hojaAD.getRange(2,25,1,2)
// Logger.log("DEBUG: copiaYZ2 is "+copiaYZ2.getA1Notation())
var destinationRangeYZ = hojaAD.getRange(2,25,(copiaA2LR-1),2)
// Logger.log("DEBUG: destination rangeYZ = "+destinationRangeYZ.getA1Notation())
copiaYZ2.copyTo(destinationRangeYZ)
}
