Mileage Log

Mileage Log from Google Maps is an app that converts your Google Maps Timeline into a structured, audit-ready mileage log with minimal manual work.

How it works
Start by downloading your Google Timeline data and uploading it into the app. The system processes your location history and converts it into a list of trips, including dates, start and end points, routes, and calculated distances. Instead of rebuilding trips manually, you get a ready-to-review log generated from actual recorded data. This approach removes guesswork and ensures your mileage is based on real historical movement rather than estimates.

Trip review and editing
Each trip can be reviewed and edited. You can classify trips as business or personal, adjust routes, merge or split trips, and fill in missing details such as purpose or notes. This allows you to fully customize your mileage log while keeping it accurate. Bulk editing options make it easy to apply changes across multiple trips, saving time when working with large datasets.

Error detection and compliance support
The app automatically flags potential issues such as missing trips, overlapping entries, inconsistent distances, or gaps in tracking. It then suggests fixes so your mileage log aligns with IRS documentation standards. This helps reduce the risk of rejected deductions or audit issues. Built-in validation ensures your records remain consistent and defensible.

Desktop dashboard (optional)
For more advanced use, a desktop dashboard provides a full overview of your mileage data. You can navigate long time ranges, filter trips by category, and perform bulk edits efficiently. This is especially useful for users managing months or years of historical data.

Export and reporting
Once your data is verified, you can export your mileage log in Excel, CSV, or PDF format. Reports include structured trip details and totals, making them ready for accountants, tax filing, or audit submission. The consistent formatting removes the need for additional spreadsheet work.
