如果单元格值 = x，则有效地将行复制并粘贴到另一个工作表

Question

I'm in the planning phase for a piece of code that I am implementing. I wanted to know what is the most efficient way to copy and paste a row of values to another tab if the value in column "x" equals a certain value.

Here are the methods I'm thinking of. I just want to know which is the most efficient as far as speed of execution and # of lines of code.

• Filter sheet and copy results to new tab.
• Loop through each row and copy them over to new tab if value in cell equals what we are looking for.
• Loop through each row and push to array if value in cell equals what we are looking for. Then paste array values to new tab.

Any other methods I missed?

Example:

In the above I'd like to copy over the rows with values "xyz" in column D to a new tab.

Edit: I'm going through a minimum of 8K lines on a spreadsheet so speed of execution is key.

Copy from Sheet3 and Paste in Sheet2 all the rows excluding those rows where HDR10 is Even and HDR1 is Odd and HDR6 is between 50 and 80

function runOne() {
  var ss=SpreadsheetApp.getActive();
  var sh=ss.getSheetByName('Sheet3');
  var dsh=ss.getSheetByName('Sheet2');
  if(dsh.getLastRow()>1) {
    dsh.getRange(2,1,dsh.getLastRow()-1,dsh.getLastColumn()).clearContent();
  }
  var rg=sh.getRange(2,1,sh.getLastRow()-1,sh.getLastColumn());
  rg.setBackground('#ffffff');//sheet3 background white
  var vA=rg.getValues();
  var hA=sh.getRange(1,1,1,sh.getLastColumn()).getValues()[0];//get sheet3 headers labels
  var idx={};
  hA.forEach(function(h,i){idx[h]=i;});//relates header name to array index
  var d=0;
  for(var i=0;i-d<vA.length;i++) {
    //delete row if HDR10 is even and HDR1 is odd and HDR6 is between 50 and 80 non inclusive
    Logger.log('i:%s , d: %s, HDR10: %s, HDR1: %s, HDR6: %s',i,d,vA[i-d][idx['HDR10']],vA[i-d][idx['HDR1']],vA[i-d][idx['HDR6']]);
    if(Number(vA[i-d][idx['HDR10']])%2==0 && Number(vA[i-d][idx['HDR1']])%2==1 && Number(vA[i-d][idx['HDR6']])>50 && Number(vA[i-d][idx['HDR6']])<80) {
      vA.splice(i-d++,1);//filter out the ones we do not want
      sh.getRange(i+2,1,1,sh.getLastColumn()).setBackground('#ffff00');//highlight the copied rows
    }
  } 
  dsh.getRange(dsh.getLastRow()+1,1,vA.length,vA[0].length).setValues(vA);
}

Sheet3

Sheet2

Although copying and pasting is fast sometimes the job of extracting only the rows you want may slow down the process considerably.
