将单元格复制并粘贴到特定列谷歌表格中的第一个空行

Question

I am trying to copy and paste values of cell J3 from Activity Report to the first empty cell in column L.

The cell to copy is fixed, but the cell to paste in is variable.

So far the code I am using has only been able to copy the values from J3 to the last row of column L instead of the first blank row from the top. Any attempt to manipulate the destination has been unsuccessful. I was able to have it paste at the top but it kept overwriting the same cell.

   function copyData() {
   var ss = SpreadsheetApp.getActiveSpreadsheet();
   var sName = ss.getSheetName();

if (sName == 'Activity Report'){
  var source = ss.getRange("Activity Report!J3");
  var destSheet = ss.getSheetByName("Activity Report");
  var lastRow = destSheet.getLastRow();

  var destination = destSheet.getRange("L"+lastRow);
  destination.activate();
  source.copyTo(destination, SpreadsheetApp.CopyPasteType.PASTE_VALUES, false);
  };
}

Thanks in advance!

Copying data to first empty cell in Columnn L

Copy value from J3 to bottom of column L

function copyData() {
  var ss=SpreadsheetApp.getActive();
  var sh=ss.getSheetByName('Activity Report');
  sh.getRange(sh.getLastRow()+1,12).setValue(sh.getRange(3,10).getValue());
}

Try this:

This will put it into the very first empty cell in column L which could be the lastRow()+1 if there are no blanks.

function runOne() {
  var ss=SpreadsheetApp.getActive();
  var sh=ss.getSheetByName('Activity Report');
  var f=false;
  var L=sh.getRange(1,12,sh.getLastRow()+1,1).getValues().map(function(r,i){if(!f && r[0].toString().length==0){f=true;return i+1;}else{return '';}}).filter(function(e){return e;});
  sh.getRange(L,12).setValue(sh.getRange(3,10).getValue());
}

This uses reduce:

If nothing else it's a bit simpler.

function copyData() {
  var ss=SpreadsheetApp.getActive();
  var sh=ss.getSheetByName('Activity Report');
  var f=false;
  var L=sh.getRange(1,12,sh.getLastRow()+1,1).getValues().reduce(function(a,r,i){if(!f && r[0].toString().length==0){f=true;return a + i;}return a;},1);
  sh.getRange(L,12).setValue(sh.getRange(3,10).getValue());
}
