CalendarTools

CalendarTools is a channel about managing calendars as systems, not just interfaces.

The channel is run by a Google Diamond Product Expert with 15+ years of hands-on experience working with calendars, scheduling systems, and calendar APIs. That includes deep, real-world experience with Google Calendar, Outlook, and the edge cases that appear at scale.

Here you’ll find tools, tutorials, and practical guidance for working with calendars beyond what the default UI allows: bulk editing, duplicate removal, spreadsheet-driven control and solutions to various problems with Google and Outlook Calendars. 

CalendarTools is the umbrella behind:
• Sheets2GCal: Google Calendar ↔ spreadsheet control
• GCalToolkit: advanced Google Calendar operations
• GCalPlus: Google Calendar UI enhancements
• Excelendar: Outlook calendar control from Excel/Browser

The focus is not productivity hacks, but correctness, scale, and control.
