GCalToolkit is a power tools for Google Calendars, allows you to manage your Google Calendars, remove duplicates, multiple edits & deletes. If you are using Outlook, iCal, Sunbird or any smartphone (such as iPhone, Blackberry or Droid) that can sync to Google, then set up 2-way sync between your calendar and Google Calendars to take advantage of the power of GCalToolkit - this means that you can delete duplicates, mass edit, mass delete, search/replace etc. in ANY CALENDAR SOFTWARE using it.

Alternatively, if you have an iCal (.ics) or .csv calendar file with duplicates that you need to remove, or multiple events that you need to delete, simply import the file into a blank Google Calendar, then use it to remove the duplicates, or edit/delete multiple events. When you are finished, export the result as a new iCal (.ics) file to be imported into whichever software you choose to use.

It is a VERY POWERFUL tool, and should be used with caution: if you are not entirely sure what you are doing then please BACKUP your Google calendar to iCal before you start (in Google Calendar "Settings"), and take the time to learn how it works before you use it on your mission critical calendars.
