Google Map's Timeline records where I (or at least my phone) has been throughout the day every day. Given a particular location, I'd like to see a list of times when I've been there. To get tax credit for days not spent working in a municipality I need to prove that I was out of the city on each day.

    did you ever get this figured out? – ashleedawg Aug 12 '18 at 8:55

No, Google Maps doesn't let you do that. It frustrated me as well, so I've written a python script that does just that.

You can find it here: https://github.com/matthieuheitz/google-data-analyses/blob/master/get_visit_times.py

You give it the point of interest (latitude/longitude), a date range, and you get what you want!


A brief overview of what is involved, if you have not used Python before:

  1. Install Python (the basic GUI provided is adequate)
  2. Install numpy (Windows guide)
  3. Edit get_visit_times.py with the basic Python editor with your:

    a. Location of your Google Location History JSON file

    b. Desired date range with dates in the format YYYY,M,D

    c. Point of Interest (Use the "right-click > What's here" feature on Google maps to get the GPS coordinates, and paste into the Python script)

    d. Timestamp grouping (output detail verbosity)

  4. Run the script (Run tab > Run module)

An example of the output (with medium detail (level 2), and the timeframe set to one day) is:

Loading 'C:\<your folder path>\Location History.json' ...
JSON file loaded
Extracting relevant data...
Total of points: 310779
Number of close points: 72
Point 124834  --  Date: 2018-11-24 00:24:03  --  Distance to POI: 1532m
    Group of 60 points
Point 129468  --  Date: 2018-12-01 02:58:17  --  Distance to POI: 1401m
    Group of 12 points

You can upload your Google location history (just follow the instructions) to this website: http://theyhaveyour.info/ then you can zoom in to find the location you are interested in and if you click on it you can see the list of the "timepoints" for that location.

  • I tried this. When I opened the LocationHistory.json file on the site it said "Not quite! LocationHistory.json does not look right. Extract LocationHistory.json from your zip file and drop it here." I downloaded the location history twice and opened both on theyhaveyour.info, trying both the .zip and .json files. – blearyeye Feb 8 '17 at 19:46
  • The problem is probably file size. It's 291MB. – blearyeye Feb 8 '17 at 20:14
  • Worked for me with a 387 MB json file – user1251007 Oct 17 '18 at 19:50
  • It's a good website, but I feel that a lot of it is not working properly (time filters for example) – matthieu Apr 12 '19 at 0:36

$in = Get-Content -Raw -Path  '<input file>.json'
$injson = convertfrom-json $in
$injson.Locations | export-csv locations.csv -notypeinformation

locations.csv has 4 columns: timestampMS, latitudeE7, longitudeE7, accuracy

Maybe the Elcomsoft Cloud eXplorer can do it.

Its mentioned in this article Google Timeline: How Law Enforcement Can Use Google Data.
