Bulk Create Google Calendar Events from Google Sheets
Bulk create Google Calendar events from Google Sheets with a free template. Follow Sheet2Cal setup, check your rows, and update events without duplicates.
How to bulk create Google Calendar events from a spreadsheet
Install Sheet2Cal in Google Sheets, run Set Up Event Sheet, and enter one event per row in the dates tab. Choose a destination calendar for each row, check the data, then run Create Calendar Events. Sheet2Cal writes a Status and Event ID back to the sheet so you can see which rows succeeded.
This is useful for a training schedule, class timetable, content calendar, or project plan. Start with the three example events below in a separate test spreadsheet and a calendar you can edit. Leave attendees empty until you have checked the results: creating events with attendees sends invitations.
1. Install Sheet2Cal and set up the event sheet
Open Google Sheets in a desktop browser. Install Sheet2Cal from the Google Workspace Marketplace using the Google account that has access to your destination calendar, then refresh the spreadsheet if the menu is missing.
Open Extensions → Sheet2Cal → 2. Set Up Event Sheet. The add-on creates a dates tab and a quick guide. In dates, row 1 is an instruction banner, row 2 contains the headers, and events start on row 3. Keep the tab name, header row, and column order intact; Sheet2Cal reads these fixed positions.
- Use a calendar where you have permission to create and edit events. Seeing a shared calendar does not always mean you can change it.
- Check File → Settings in Sheets and the destination calendar's settings for their time zones. Use the same time zone for your first test and confirm how the event displays in Calendar.
- The Create and Sync commands process the dates tab, including eligible rows outside your selection. Selecting three rows does not limit the batch to those rows.
2. Start with the three-event template
The downloadable spreadsheet uses Sheet2Cal's exact 16-column layout, with two timed events and one all-day event. Dates are real spreadsheet dates. Calendar, attendees, Status, Event ID, and Action are blank so you can choose where the test runs without inviting anyone.
Upload the file to Google Drive, open it in Google Sheets, and use File → Save as Google Sheets if it is still an Excel file. Run 2. Set Up Event Sheet in the converted spreadsheet to add the calendar dropdowns. Choose your test calendar in A3:A5 and change the example dates to dates you want to test.
If you already created a fresh dates tab in step 1, you can instead copy B3:M5 from the converted template into B3 of that tab. This copies only the sample event details. Choose your calendars in column A afterward, and keep N:P blank for these new events.
| Title | Start Date | Start / End Time |
|---|---|---|
| Project kickoff | 9:00 AM – 9:30 AM | |
| Team training | 2:00 PM – 3:00 PM | |
| Launch deadline | Both blank (all-day) |
The preview shows the main fields. The download includes all 16 columns, in the order Sheet2Cal expects.
3. Fill the required columns and check dates and times
Every event needs a Calendar, Title, and Start Date. Timed events also need both a Start Time and an End Time. End Date is optional for a same-day event; an overnight event needs the following date in End Date.
Use the date picker for date cells. Merely changing a text cell's display format to Date does not guarantee it contains a valid date. For times, enter values such as 9:00 AM or 14:30. The end date and time must be later than the start date and time.
- For a one-day all-day event, leave Start Time, End Time, and End Date blank. You can also enter All-day in Start Time, with End Time blank.
- For a multi-day all-day event, End Date is exclusive: an event covering October 12–14 ends on October 15. Test this before creating a longer schedule.
- Enter one complete email address in each Attendee cell, up to four per event. Do not put a comma-separated list in one cell. Leave all four blank for your first test.
| Column | Field | What to enter |
|---|---|---|
| A | Calendar | Required. Choose a calendar you can edit from the dropdown. |
| B | Title | Required. This becomes the Calendar event title. |
| C | Start Date | Required. Use a real date cell, such as October 12, 2026. |
| D | Start Time | Required for timed events. Use 9:00 AM or 14:30; blank means all-day. |
| E | End Date | Optional for same-day events. Set it for overnight or multi-day events. |
| F | End Time | Required for timed events, later than the start. Leave blank for all-day events. |
| G–I | Description · Event Color · Address | Optional. Add an agenda, choose an event color, or enter a location. |
| J–M | Attendee 1–4 | Optional. One email per cell, up to four guests. Creation sends invitations. |
| N–O | Status · Event ID | Written by Sheet2Cal. Leave blank for new events; preserve after creation. |
| P | Action | Leave blank unless you deliberately want to delete a linked event with Pro. |
4. Check the rows, create the events, and verify the result
Open Extensions → Sheet2Cal → 3. Check Event Rows. Fix the reported calendar, date, time, or attendee problems before continuing. Checking rows does not create events. A calendar may still reject an event if your account lacks edit permission.
Then run 4. Create Calendar Events. Successful rows receive Success in column N and an Event ID in column O. Open the destination calendar and check the title, date, start and end times, description, and location. Verify the all-day example separately.
A batch can partly succeed. If one row fails, read its Status, fix that row, and run Create again. Rows with an Event ID are skipped; keep successful rows' IDs and statuses intact. Once the test is correct, add the rest of your schedule below the headers. The free plan allows up to 10 event creations or imports per day; Pro is needed for larger batches and syncing sheet changes, subject to Google's service limits.
5. Update existing events without creating duplicates
With Sheet2Cal Pro, edit the existing row and run 5. Sync Sheet Changes (Pro). Keep its Calendar in column A and Event ID in column O. These identify the event to update. Changes are sent when you run the command; editing a cell alone does not automatically sync Calendar.
For example, change Project kickoff from 9:00–9:30 AM to 10:00–10:30 AM in the same row. Leave the Event ID in place and run Sync Sheet Changes. Check that the existing Calendar event moved to the new time. A changed row reports Synced; there should still be one kickoff event.
Do not clear IDs to retry a batch, copy linked rows as new events, or change the Calendar cell expecting to move an existing event between calendars. Sync also applies the row's attendee list, so preserve guests you still want on the event.
Removing a row from the spreadsheet does not delete its Calendar event. To deliberately delete a linked event with Pro, type DELETE in that row's Action cell and run Sync Sheet Changes. Review all Action cells first because the command processes the whole dates tab.
Troubleshooting your first bulk import
Use the row's Status and Check Event Rows to narrow down the problem. Keep the successful rows intact while you fix failed ones.
- Calendar is missing or inaccessible
- Choose the correct calendar in column A while signed into the account that can edit it. Ask its owner for edit access if necessary.
- Invalid date or time
- Use the date picker for Start Date and any End Date. For timed events, enter both times and make the end later than the start; use a next-day End Date for overnight events.
- Event appears at the wrong time
- Compare the spreadsheet and destination calendar time zones, plus the time zone used to display Google Calendar. Correct the row and use Sync Sheet Changes (Pro) for an existing event.
- Invalid attendee email
- Use one full email address per Attendee cell. Remove comma-separated lists, spaces around addresses, and incomplete emails.
- Event missing
- First verify the Calendar cell, account access, and whether the event was deleted in Google Calendar. Only after confirming it is gone, clear that row's Event ID and run Create Calendar Events to recreate it. Do not clear IDs for events that still exist.
- Free daily limit reached
- Keep completed rows intact. Run the remaining new rows after the quota resets, or use Pro for larger batches. Google's service limits still apply.
- Changed a cell but Calendar did not update
- Sheet edits do not sync automatically. Keep the existing Event ID and run Sync Sheet Changes (Pro).
Frequently asked questions
Can I bulk create Google Calendar events without Apps Script?
Yes. Sheet2Cal adds setup, row checking, and event creation commands to Google Sheets. Use its dates tab with one event per row; you do not need to write or maintain a script.
Does Sheet2Cal sync automatically when I edit a cell?
No. Run Create Calendar Events for new rows, or Sync Sheet Changes (Pro) to update linked events. Do not assume that changing a Calendar event will automatically write the change back to your sheet.
Will running Create Calendar Events twice create duplicates?
Rows that already have an Event ID are skipped during creation. Keep the Event ID and Status columns intact after a successful run. If you remove that tracking information or paste the same event into a new unlinked row, you can create duplicates.
Can I send guest invitations from Google Sheets?
Yes. Put one email address in each of the four Attendee columns. Creating the event sends invitations to those guests. Keep the attendee columns blank while testing your first batch.
Is the template a Google Calendar CSV import file?
No. This template is for Sheet2Cal's dates tab inside Google Sheets, with its fixed columns and Event ID tracking. Do not upload it to Google Calendar's CSV importer, which uses a different file layout.
Can I create events on a shared calendar?
Yes, if your signed-in Google account has permission to create and edit events on that calendar. Select the calendar for each row. Read-only access is not enough, and your organization may restrict add-ons or Calendar permissions.
