Select and copy some values from spreadsheet comparing to another column on another sheet

Question

I have read these two links Google Script: Conditionally copy rows from one spreadsheet to another and https://stackoverflow.com/a/4809413/1526044 and after trying I am not able

Answer 1

I modified a similar script I answered recently that should do what you need. I didn't test but you can give it a try. There are some comments to explain the idea... it probably needs some debugging.

EDIT : I played around with this and debugged it a bit more ;-) so it seems to work as needed now - here is the link to my test sheet

function xxx(){ 
/* we have an array 'keysheet'
    and an array datasheet , you get these with something like*/
        var keysheet = SpreadsheetApp.getActiveSpreadsheet().getSheets()[0].getDataRange().getValues();
    // and
        var datasheet = SpreadsheetApp.getActiveSpreadsheet().getSheets()[1].getDataRange().getValues();// if other columns, change index values in the arrays : 0=A, 1=B ...
    // the iteration could be like this :
              for(i=0;i<datasheet.length;++i){ // don't miss any data
                for(j=0;j<keysheet.length;++j){ // iterate through keysheet to find the keys
                  for(k=1;k<keysheet[0].length;++k){ // iterate in keysheet row to check every column except first one
                      var key = keysheet[j][k]
                      Logger.log(k+' '+key+"  "+datasheet[i].toString().match(key))
                 if(datasheet[i].toString().match(key) == key){// check whole rows to find if key is in data
                  var x = datasheet[i].shift();
                   datasheet[i].unshift(keysheet[j][0]) // if match found, replace first element in datasheet with fisrt element in keysheet
                     break  // if found break k loop maybe you should also break j loop ?
                       }
                 }
                   } //loop keysheet
             } // loop datasheet

            /* now you have a modified datasheet array that can directly overwrite the old datasheet 
            using setValues() */
            var sh = SpreadsheetApp.getActiveSpreadsheet().getSheets()[1];// assuming the datasheet sheet is sheet nr2
            Logger.log(datasheet)
           sh.getRange(1,1,datasheet.length,datasheet[0].length).setValues(datasheet);
              }
        //
