GCalToolkit and GTasksToolkit Cracks and Serials

If you came here looking for cracks or serial... you have come to the right place ;-) Before you do something as stupid as installing a keygen on your precious machine, I can save you the trouble as I have tested most of the cracks and serials on youtube and torrent sites: not only will none of them actually get you GCalToolkit or GTasksToolkit for free, but without exception they install malware and/or spyware to your machine which could put your computer and Google account at serious risk. If you really are too poor to pay for the tools you need, then please drop me a line explaining your situation, and what you could offer do for in lieu of payment - the worst thing that can happen is that I might say no.


GCalToolkit Feature List


  • Load multiple calendars from a Google Calendar account. This allows you to remove duplicates that are spread across several calendars (and select a "preferred calendar" in which to leave the original event), and search, delete, view or export events across multiple calendars within a single account.
  • Make mass changes to "Busy/Free" status, Privacy, "Guests Can Modify", and Reminders based on your chosen filters and/or manual selection.
  • Copy/Move events between calendars within an account. This allows you to split a calendar into several secondary calendars. For example, you can move all events with "Birthday" in the title to a new "Birthdays" calendar... or move all your "Busy" events into a separate "Busy" calendar... or put all your repeat events into a "Recurring Events" calendar.
  • New! Shift events forwards or backwards in time, and create duplicate events to repeat at regular intervals: when you copy/move you can check the option "Shift Events" to change the time/date of all the highlighted/visible events. This lets you replicate days, weeks or even entire months without having to copy each event by hand. This can be very useful for rescheduling timetables or  work shifts that follow patterns that do not work well with ordinary repeats. Although this function can also be used to create "fake" repeats please consider using genuine repeats whenever possible. The shift function will also allow you to change the time/date for repeat events, and will even shift exceptions to repeat rules and end dates defined by a date; as usual please back up first, just in case.
  • Make mass changes to your reminders: With GCalToolkit you can reset thousands of reminders to either the default reminder (pop-up, email to be configured in your calendar settings), or no reminder at all.

  • Case Sensitive/Insensitive text filtering with positive or negative search, and regex support
  • Automatically attach Google Drive files to calendar events (see options for help)
  • Column hide/show and sorting for most event properties
  • Totals display for edits/deletes/copy/move etc
  • Improved logic to eliminate unnecessary event updates
  • Colour coded cell backgrounds when events are marked for edit, copy, move, delete etc.
  • Total control of spreadsheet output columns
  • Sort, filter and edit with any criteria: e.g set all meetings before 2017 to private and move them into a different calendar

Please export your Google Calendars as an iCal File (under Settings > Calendars > "Export") BEFORE using GCalToolkit - the software is very safe, but too powerful to use without making a backup first.
