Calendar Mapper turns your Google Calendar™ appointments into a mileage log in Google Sheets™. It reads each event's location, measures the driving distance between every stop on Google Maps™, and writes the log for you.

How It Works
📍 Set where you start — enter your home or base address once. Each day's first drive can start at Home, at your first appointment, or at a custom address, and the last drive can end anywhere you choose.
📅 Pick calendars and dates — choose one or more Google Calendar™ calendars and any date range, from a single day to a full year.
📄 Click Import — every appointment gets a row with the driving distance from the stop before it, a subtotal for each day, and a total for the period.

What You Get
🗺️ Real road miles — distances are Google Maps™ driving routes, not straight-line estimates. Choose miles or kilometers, and add travel time if you want it.
🧾 The details stay with the number — each row carries the event title, start and end time, description and location, so the reason for each drive is written next to it.
🏆 Daily subtotals and a period total — if any trip could not be measured, the total says how many are missing, so a gap never hides in a number that looks complete.
💻 Appointments without an address stay visible — a video call is listed with no mileage, so your log still matches your calendar.
🚗 Commute deduction — enter your normal commute once and it is subtracted from each day's first and last drive.
📊 A Trips tab for reports — the same data as one flat row per drive (date, weekday, month, origin, destination, miles), ready for a pivot table by month or client.
🔄 Auto-Update — refresh the sheet every day or every hour on a rolling window, such as the last 30 days.
🎛️ Detail Level — show every column, or trim the log down to start, end and miles, or to drives only.

FAQ

Does Calendar Mapper work with multiple calendars?
Yes. You can select one or more of your Google Calendar™ calendars to include in each import. Useful if you maintain separate calendars for different clients or business lines.

What if an event doesn't have an address?
It is listed as "No Location" with no mileage, so your log still matches your calendar and you can see what was left out. Add the address to the calendar event and import again.

How does it decide where each drive starts?
The first drive of each day starts from Home, your first appointment, or a custom address, whichever you choose in Trip Logistics. Every later drive starts from the previous appointment. Two checkboxes send you home between events, or home at the end of each day.

Can I leave out my commute?
Yes. Enter your one-way commute distance in User Settings and it is subtracted from each day's first and last drive, shown as negative rows you can see.

Does it count toward my Google Maps™ quota?
Yes. Calendar Mapper uses the Google Maps™ API, which has daily limits that depend on your account type. Most people logging a month of visits stay well inside them. If a day's limit is reached, the total tells you how many trips are missing; running the import again the next day fills them in.
