Free Google Maps Timeline Export to Excel is a Chrome extension that allows users to export their trips and mileage from Google Maps Timeline to Excel. This feature is particularly useful for individuals who need to track their mileage for tax deduction purposes. With this extension, users can easily generate mileage and time sheet reports or exports.

One important thing to note is that the extension emphasizes that the exported trips from Google Maps Timeline, regardless of the tool used, are not sufficient as an IRS-Proof mileage log. According to the extension's Platinum sponsor, MileageWise, their software is capable of converting these exported trips into an IRS-Proof mileage log.

A key feature of Free Google Maps Timeline Export to Excel is that it prioritizes user privacy. None of the location data is sent through a server. Instead, all processing is done locally in the user's browser, ensuring that their privacy is protected.
