Google Apps Script

Change alternate row background colors in Spreadsheet using Google Apps Script

August 22, 2011 By Ravi Shankar 8 Comments

Here is a Google Apps Script that would set the background color of alternate rows in Google Spreadsheet. This script would set the background color of of the selection, this may not be an efficient script but would do the job.

Let us take the following sample data which will be used by the script for setting the background color.

Install the below script and select the data by excluding the Header columns and execute the script.

function alternateColor() {
  var totalRows = SpreadsheetApp.getActiveRange().getNumRows();
  var totalColumns = SpreadsheetApp.getActiveRange().getNumColumns();
  var startRow = SpreadsheetApp.getActiveRange().getRow();
  var startColumn = SpreadsheetApp.getActiveRange().getColumn();
  var sheet = SpreadsheetApp.getActiveSheet();
  var row = startRow;
  while (row < totalRows+startRow)
  {
    var column = startColumn
    while (column < totalColumns+startColumn){
      if(row%2 == 0){
           sheet.getRange(row, column).setBackgroundColor(“lightgrey”);
      }
      column++;
  }
    row++;
  }
}

After executing the script, the sample data would look as shown below.

If you want to change the white color then you can add an else statement to set the background color for odd row numbers as well.

if(row%2 == 0){
           sheet.getRange(row, column).setBackgroundColor(“lightgrey”);
      } else {
          sheet.getRange(row, column).setBackgroundColor(“lightblue”);
}

Let me know if any one have a better suggestionn.
