How to copy bulk of data to a given range? - google-apps-script

Question

Hello so I am trying to get values from the 'book' sheet then copy it to 'Completed' sheet. It doesnt give any error but doesnt do the copying too. It takes the values form book stores it in the data array but doesnt copy them to the 'Completed' sheet. So I guess there is a problem with the last row.
var sheet = spreadsheet.getSheetByName('Book'); //source sheet
var Datarange = sheet.getRange('Q:Q'); //range to check
var Datavalue = (Datarange.getValues());
var dest = spreadsheet.getSheetByName('Completed'); //destination sheet
var data = [];
var j =[];
for (i=0; i<Datavalue.length;i++) {
if ( Datavalue[i] == "Completed") {
data.push.apply(data,sheet.getRange(i+1,1,1,24).getValues());
j.push(i);
}
}
dest.getRange(dest.getLastRow()+1,1,data.length,data[0].length).setValues(data); /// copy data to range

Something like this:
function whoknowswhat() {
var ss=SpreadsheetApp.getActive()
var sh=ss.getSheetByName('Book');
var rg=sh.getRange(1,17,sh.getLastRow(),1);
var v=rg.getValues();
var dest=ss.getSheetByName('Completed');
var data=[];
for (i=0; i<v.length;i++) {
if (v[i][?]=="Completed") {//need another parameter for column
data.push(v[i]);//v[i] is an entire row
}
}
dest.getRange(dest.getLastRow()+1,1,data.length,data[0].length).setValues(data);
}
