If you manage important calendars using Google Calendars, GCalToolkit is the software you need to keep everything neat and tidy - and it comes with unlimited personal support for all your calendar problems.
The most common uses include removing duplicate events caused by calendar sync problems, and deleting or moving events between calendars to keep the size of your synced calendars to a minimum, while keeping older data available for reference.
You can customise the column view and export spreadsheets, add prefixes/suffixes to event titles, replace text throughout multiple calendars, apply case sensitive filtering, make mass edits to the busy/free status of groups of events, make mass edits to reminders or privacy, delete Guests and more.
