quicksheet-cal

📅 Calendar extension for QuickSheet — see upcoming events from .ics files right on your desktop spreadsheet.

Install

In any QuickSheet cell:

ext: github:Deskworks/quicksheet-cal

Usage

Cell value	What it shows
cal: ~/calendar.ics	Events from a specific .ics file
cal: today	Today's events (auto-scans common calendar dirs)
cal: week	Next 7 days (default)
cal: month	Next 30 days
cal: 14	Next N days

How it works

The extension parses iCalendar (RFC 5545) .ics files directly — no external dependencies, no NuGet packages, no API keys.

When no file path is given, it scans common calendar directories:

• GNOME Evolution — ~/.local/share/evolution/calendar/local/
• GNOME Calendar — ~/.local/share/gnome-calendar/local/
• Thunderbird — ~/.thunderbird/ (recursive)
• KDE Akonadi — ~/.local/share/akonadi/
• Calcurse — ~/.local/share/calcurse/ or ~/.calcurse/
• Drop folder — ~/Calendars/ or ~/.calendars/
• Windows — Documents/Calendars/

Export your Google Calendar, Outlook, or Apple Calendar as .ics and drop it into any of these locations.

Output

Events are displayed grouped by date with smart labels:
