Google Calendar Timesheet Integration — How to Set Up

Google Calendar Timesheet Integration — How to Set Up

Your Google Calendar is already the most accurate record of how you spend your work day. Every meeting, focus block, client call, and team sync is logged with precise start times, end times, and descriptions.

So why are you retyping all of that into a separate timesheet?

This guide walks you through setting up a Google Calendar timesheet integration that auto-generates your weekly timesheet — no coding, no plugins, no IT department required.

What You Need

• A Google Calendar account (personal or Google Workspace)
• A browser (Chrome, Firefox, Safari, or Edge)
• 60 seconds

That is it. No API keys, no spreadsheet formulas, no Zapier workflows.

Step-by-Step Setup Guide

Step 1: Go to FillTheTimesheet

Open fillthetimesheet.com in your browser. No account creation needed for the free plan.

Step 2: Click "Connect Google Calendar"

You will see the Google OAuth consent screen. FillTheTimesheet requests read-only access to your calendar events. We cannot create, edit, or delete anything in your calendar.

What permissions are requested:

• View calendar events and details (read-only)


• View your email address (to identify the calendar)

What is NOT requested:

• Write access to your calendar


• Access to your contacts, Gmail, or Drive


• Any offline or background access

Step 3: Select Your Date Range

Choose the date range for your timesheet:

• Free plan: Up to 7 days per export
• Pro plan: Unlimited date range (weekly, biweekly, monthly, custom)

Step 4: Review Your Events

FillTheTimesheet displays all calendar events in a clean, editable table. You can:

• Edit event titles — rename "Quick sync" to something more descriptive
• Assign categories — tag events as "Client Work," "Internal," or "Admin"
• Exclude events — skip personal appointments or lunch blocks
• Merge events — combine related back-to-back meetings

With AI Smart Categorization (Pro), this step is mostly automatic — the AI learns your patterns and pre-assigns categories based on event titles, attendees, and calendar source.

Step 5: Choose Your Export Template

Select the export format that matches your company's timesheet system:

Template	Best For
Standard	Simple weekly timesheets (date, task, hours)
Detailed	Timesheets requiring attendee and location info
Daily Summary	Aggregated hours per day
Client Billing	Grouped by client/project with billable totals
Custom Upload	Your company's exact spreadsheet format

Step 6: Export to Excel

Click "Export" and download your .xlsx file. Open it in Excel, Google Sheets, or LibreOffice — or upload directly to your HR/project management portal.

Done. Your timesheet is complete.

Advanced Setup: Multiple Calendars

Most professionals have more than one calendar. FillTheTimesheet supports aggregating events from multiple sources in one export:

• Google Calendar (personal + workspace) — Free plan
• Microsoft Teams — Pro plan
• Zoom — Pro plan
• Jira — Pro plan (logs as tasks, not meetings)
• ClickUp, Asana, Monday.com — Pro plan
• Toggl Track — Pro plan

All events are merged into a single timeline and deduplicated automatically.

Advanced Setup: Custom Template Mapping

If your company uses a specific timesheet format, you can upload your template and map columns:

1. Upload your company's .xlsx timesheet template
2. Drag-and-drop to map FillTheTimesheet fields to your template columns
3. Save the mapping for future exports

Your exported file will match your company's exact format — no reformatting needed.

Privacy and Security

This is important — especially if your calendar contains confidential client meetings or internal strategy sessions.

FillTheTimesheet processes everything in your browser. Calendar data is fetched via Google's API directly to your device. It is never sent to our servers, never stored in a database, never logged.

• Read-only OAuth access (we cannot modify your calendar)
• Client-side processing (no server-side data storage)
• Revoke access anytime from Google Account Permissions
• Compliant with Google's Limited Use Policy

Common Questions

Q: Will this work with Google Workspace (company accounts)?
Yes. FillTheTimesheet works with both personal Gmail calendars and Google Workspace accounts. Your IT admin may need to allow the OAuth app if your organization restricts third-party access.

Q: Can I set it up to run automatically every week?
The free plan requires a manual export each week. Pro users can save their preferences and export with a single click — same configuration, new date range.

Q: What if some calendar events are personal?
You can exclude specific calendars or individual events before exporting. Only include what belongs on your timesheet.
