NimbleCal

Import from Google Calendar

Last reviewed May 14, 2026

Google Calendar exports calendars as a .zip that contains one or more .ics files. NimbleCal imports .ics files (you can import multiple at once).

Privacy note
The downloaded ICS file is plain text while it sits in Downloads, cloud storage, email, or shared folders. After you import it, the events stored in NimbleCal use the app's normal end-to-end encryption.
You got this
Google's export is a little hidden, but once you have the `.ics` files, import is quick.

Step 1: Export from Google Calendar

Google offers two export paths:

Option A: Export all calendars

This downloads a .zip file that contains one .ics file per calendar.

  1. Open Google Calendar on the web.
  2. Open Settings.
  3. Find Import & export.
  4. Choose Export.

Option B: Export one calendar

This downloads a single .ics file for that calendar.

  1. Open Google Calendar on the web.
  2. In the left sidebar, hover a calendar name and click the menu icon.
  3. Open Settings and sharing.
  4. Find Integrate calendar and choose Export calendar.

Step 2: Unzip the export

Unzip the downloaded file so you can access the .ics files inside.

Exporting multiple calendars?
Google's export gives you one `.ics` file per calendar. NimbleCal can import those files together and create a calendar for each file.

Step 3: Import into NimbleCal

In NimbleCal:

  1. In the left sidebar under My Calendars, click the + menu.
  2. Choose Import calendar.
  3. Click Browse files.
  4. Select one or more .ics files from the unzipped folder.
  5. Pick a destination. With multiple files, you can Create a calendar for each file, Import into existing calendar, or Create a new calendar that combines everything.
  6. Click Import events. With multiple files, the button label includes the file count, such as Import 3 files.
Free plan note
Creating multiple calendars at once requires a Plus plan. If you're on Free and already have your 1 calendar, import into an existing calendar.

Common issues

  • I only see a .zip file: Unzip it first, then import the .ics files.
  • Duplicates after importing: If you imported the same .ics twice, you may see duplicates. Import once per calendar export.
