Google Apps Script: Auto-Query FortiGuard Category List

In case someone is curious, here's a little Google Apps Script I put together for querying FortiGuard's Web Filtering Service site category list from a spreadsheet. It takes a URL from the selected cell in a Google Spreadsheet, and FortiGuard's category for that URL in the cell to the right of it.

function onOpen() {

  var sheet = SpreadsheetApp.getActiveSpreadsheet();

  var menuEntries = [ {name: "pasteCategory", functionName: "pasteCategory"},

                      {name: "Say Hello", functionName: "sayHello"} ];

  sheet.addMenu("FortiGuard", menuEntries);

}

function pasteCategory() { //you can also set this to loop for the number of rows

  var sheet = SpreadsheetApp.getActiveSpreadsheet();

  var range = SpreadsheetApp.getActiveRange();
  var newRange = range.offset(0, 1); //the cell to the right

  var site = range.getValue();//from the currently selected cell

  var category = getCategory(site);

  newRange.setValue(category) //paste in the category
  var newSelection = range.offset(1, 0);
  newSelection.activate();

}

function sayHello() {

  Browser.msgBox("Hello");

}

function getCategory(site) {

  var urlToFetch = "http://www.fortiguard.com/ip_rep/index.php?data="+site

  var html = UrlFetchApp.fetch(urlToFetch).getContentText();

  var startTag = 'Category: ';

  var endTag = '</h3>';

  var startIndex = html.indexOf(startTag) + 10; // add 10 to the index to get rid of 'Category: '

  var endIndex = html.indexOf(endTag);

  var category = html.slice(startIndex,endIndex);

  return(category);

}
