I want a Google Script that automatically exports the Spreadsheet to a .XLSX whenever there is an edit made, overwriting any previous versions. Using [this answer](https://stackoverflow.com/questions/12712137/google-apps-script-to-email-google-spreadsheet-excel-version/12867942#12867942) as a template, I created the following code:

```js
function onEdit() {
  var s = SpreadsheetApp.getActiveSheet();
  var r = s.getActiveCell();
  if( r.getColumn() != 1 ) { //checks the column
    var row = r.getRow();
    var time = new Date();
    time = Utilities.formatDate(time, "GMT-08:00 ", "MM/dd/yy, hh:mm:ss");
    SpreadsheetApp.getActiveSheet().getRange('A' + row.toString()).setValue(time); 

    var id = 'MY_SPREADSHEET_KEY'
    var url = 'https://docs.google.com/feeds/';
    var doc = UrlFetchApp.fetch(url+'download/spreadsheets/Export?key='+id+'&exportFormat=xls',
                                googleOAuth_('docs',url)).getBlob()
    DocsList.createFile(doc).rename('newfile.xls')
  };
 };

function googleOAuth_(name,scope) {
  var oAuthConfig = UrlFetchApp.addOAuthService(name);
  oAuthConfig.setRequestTokenUrl("https://www.google.com/accounts/OAuthGetRequestToken?scope="+scope);
  oAuthConfig.setAuthorizationUrl("https://www.google.com/accounts/OAuthAuthorizeToken");
  oAuthConfig.setAccessTokenUrl("https://www.google.com/accounts/OAuthGetAccessToken");
  oAuthConfig.setConsumerKey('anonymous');
  oAuthConfig.setConsumerSecret('anonymous');
  return {oAuthServiceName:name, oAuthUseToken:"always"};
}

```

However, it doesn't seem to be exporting. OR, if it is exporting, I'm not sure where this is happening.

Any ideas?
