Append only non empty cells to another sheet google script - google-apps-script

Question

I want to copy only non-empty cells in column C & E & append all of them in "Update" Sheet 1st column. Below is what i tried for copy non-empty cells but it doesnt append
here is Dummy Sheet for reference
function emaillFilter(){
var ss = SpreadsheetApp.getActiveSpreadsheet();
var ws = ss.getSheetByName("Email");
var updateSheet = ss.getSheetByName("Update");
var range = ws.getRange(1,5,ws.getLastRow());
var emptycells = SpreadsheetApp.newFilterCriteria().setHiddenValues(['']).build();
var filter = range.getFilter() || range.createFilter();
filter.setColumnFilterCriteria(5, emptycells);
var data = ws.getRange(2,5,ws.getLastRow()).getValues();
var array = [];
for (var i = 0; i < data.length; i++){
if(!ws.isRowHiddenByFilter(i+1)){
array.push(data[i]);
}
}
updateSheet.getRange(updateSheet.getLastRow()+1, 1, array.length).setValues(array);
}
input sheet Column C & E
desired output - paste column C & append E without blanks in column A of another sheet

Answer 1

How about this:
function emaillFilter(){
const ss=SpreadsheetApp.getActive();
const sh=ss.getSheetByName("Email");
const ush=ss.getSheetByName("Update");
const data=sh.getRange(2,1,sh.getLastRow(),5).getValues();
var array=[];
data.forEach(function(r,i){
if(r[2] && r[4]) {
array.push(r);
}
});
ush.getRange(ush.getLastRow()+1, 1, array.length,array[0].length).setValues(array);
}
Okay I think you want this based upon your comment:
desired output - paste column C & append E without blanks in column A of another sheet
But I must admit that I don't see that reflected in your example second image so we may need another iteration.
function emaillFilter(){
const ss=SpreadsheetApp.getActive();
const sh=ss.getSheetByName("Email");
const ush=ss.getSheetByName("Update");
const data=sh.getRange(2,1,sh.getLastRow(),5).getValues();
var array=[];
data.forEach(function(r,i){
//is columnC and columnE both truth
if(r[2] && r[4]) {
array.push([r[2] + ',' + r[4]]);
//is columnC truthy and columnE falsy
}else if(r[2] && !r[4]) {
array.push([r[2]]);
}
});
ush.getRange(ush.getLastRow()+1, 1, array.length,array[0].length).setValues(array);
}
Okay I think this is it:
function emaillFilter(){
const ss=SpreadsheetApp.getActive();
const sh=ss.getSheetByName("Email");
const ush=ss.getSheetByName("Update");
const data=sh.getRange(2,1,sh.getLastRow(),5).getValues();
var array1=[];
var array2=[];
data.forEach(function(r,i){
if(r[2]) {
array1.push([r[2]]);
}
if(r[4]) {
array2.push([r[4]]);
}
});
var array=array1.concat(array2);
ush.getRange(ush.getLastRow()+1, 1, array.length,array[0].length).setValues(array);
}
Thanks for the images. They really helped.
truthy
falsy
