On Google Spreadsheet, how do you call the CIty, Country of an IP?

After some digging I've figured out how to do this.

1. Copy the import_json_appsscript.js script on https://gist.github.com/chrislkeller/5719258. This will be the script that will create the ImportJSON() function to a Google spreadsheet

2. Go to Google spreadsheet, on the menu bar got to Tools > Script Editor

3. Copy paste import_json_appsscript.js into the Script Editor and save it, Double check that you can see the ImportJSON() function on the Select function drop down menu.

4. On the Spreadsheet use function =ImportJSON(url, query, options), for example =ImportJSON("http://freegeoip.net/json/75.148.30.137", "/city", "noHeaders") to retrieve Baltimore from the FreeGeoIP call.

Hope that helps, it certainly answers my question.
