Bulk Edit Calendar Events is a program designed to just that – edit your calendar events in bulk.
Have you ever wanted to delete a bunch of extraneous events? Or maybe rename a group of events that aren’t connected? In Google Calendar, the only option for editing multiple events at once is with recurring events. If the events aren’t recurring events, your only option is the slow, tedious method of editing them one-by-one.
With Bulk Edit Calendar Events I have drastically simplified this process. Simply get a list of all your calendar’s events (according to criteria you specify), filter the retrieved events (optional), then specify the properties you would like to change for all of them! For a large number of events, this can cut time from a few hours down to a couple minutes!
