merge values in column in a row with the quotes separator “|”, based on a comparison with the values of another column

Question

as the title suggests I\'m trying to find a way to treat some data in a spreadsheet to google app. I think the best way is to directly set an example and thank you in advan

Answer 1

have a look at this post, he want to do almost the same. Modifying 2 lines of the code and it's done:

function myFunction() {
  var objList={};
  var ss = SpreadsheetApp.getActive().getActiveSheet();
  var data = ss.getDataRange().getValues();
  for(var i in data){
    // for(var j in data[i]){
      if(typeof objList[data[i][0]]=="undefined"){
        objList[data[i][0]]=[]; // new array
        objList[data[i][0]].push(data[i][1]); // push the value of the second column
      }
      else{
        objList[data[i][0]].push(data[i][1]);
      }
    //}
  }
  var objTable=[];
  for(var k in objList){
   objTable.push([k,objList[k]]);
  }
  Logger.log(objTable);
  ss.clear();
  ss.getRange(1, 1, objTable.length, objTable[0].length).setValues(objTable);
}

Answer 2

Here is a code that does exactly what you expected using a simple loop and a comparison.

function merge_col() {
  var ss = SpreadsheetApp.getActive().getSheetByName('sheet1');
  var data = ss.getDataRange().getValues();
  var header = data.shift();
  var col1 = data[1][0];
  var col2 = '';
  var col3 = '';
  var dataSheet2 = [header];
  for(var i=0 ; i<data.length ; i++){
    Logger.log(data[i][0]+'  -  '+col1+'  -  '+data[i][2])
    if(col1==data[i][0]){
      col1 = data[i][0];
      col2+=data[i][1]+' | ';
      col3+=data[i][2]+' | ';
    }else{
      dataSheet2.push([col1,col2,col3]); 
      var col1 = data[i][0];
      col2 = data[i][1]+' | ';
      col3 = data[i][2]+' | ';
    }
  }
  dataSheet2.push([col1,col2,col3]); 
  Logger.log(dataSheet2);
  var sheet2 = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('sheet2');
  sheet2.clear();
  sheet2.getRange(1, 1, dataSheet2.length, dataSheet2[0].length).setValues(dataSheet2);
}
