Product

Device & OS
not provided
Scenario
Exporting Google Calendar event details to an Excel spreadsheet using a Power Automate flow.
Observed behavior

Before you start

Ensure you have editing access to your Power Automate flow and confirm the exact local time zone your Google Calendar and Excel workbook are supposed to use.

Solution 1Recommended

Use the Convert Time Zone Action in Power Automate

The most reliable way to fix the one-hour offset is to explicitly convert the UTC time to your local time zone within the flow.

Power Automate processes time in Coordinated Universal Time (UTC) by default. If your local time zone or Daylight Saving Time isn't explicitly accounted for before writing data to Excel, the timestamps will be offset.

1
Edit the Power Automate Flow

Open your Power Automate dashboard, locate the flow that syncs Google Calendar to Excel, and click 'Edit'.

2
Add a Convert Time Zone Action

Click the '+' icon to add a new step just before the 'Add a row into a table' Excel action. Search for 'Convert time zone' and select it.

3
Configure the Time Conversion

In the Base time field, select the dynamic content from Google Calendar (e.g., Start Time). Set the Source time zone to '(UTC) Coordinated Universal Time' and the Destination time zone to your actual local time zone.

4
Update the Excel Action

In your Excel action step, replace the original Google Calendar time dynamic content with the 'Converted time' output from the new conversion step. Save and test your flow.

Format String Configuration: You can use the 'Format string' dropdown in the Convert time zone action to ensure the date and time match your preferred Excel formatting (e.g., 'yyyy-MM-ddTHH:mm:ss').

Frequently Asked Questions

Why does Power Automate export dates in UTC?

Power Automate standardizes date and time values using Coordinated Universal Time (UTC) to prevent conflicts across global servers and interconnected cloud services. It requires explicit conversion actions to display your local time.

Can Daylight Saving Time (DST) cause this one-hour difference?

Yes. If your Google Calendar correctly adjusts for DST but your Excel environment or Power Automate flow does not (or uses a fixed timezone offset), a one-hour discrepancy will appear during the affected months.

How do I format the converted time to look exactly how I want in Excel?

In the Power Automate 'Convert time zone' action, you can select a specific 'Format string'. Choose a standard layout from the dropdown or input a custom string like 'yyyy-MM-dd HH:mm' so the output matches your desired Excel layout perfectly.
