This is a tutorial for using the OpenCage geocoding API in Google Docs.

Please note

  • This Google sheets plugin is designed as a way to quickly test our service or to do a small (< 1,000) volume of geocoding. It is not designed for high volume production use.
  • If your spreadsheet geocoding needs are more complex, in your account dashboard you can upload a spreadsheet which we will geocode row by row for you.

Let's start

  1. Sign up for an OpenCage Geocoding API key, or if you already have one log in.

  2. Are you sure you don't want to just use our spreadsheet uploading service?
  3. Create a new Sheet

    Put your addresses in a column, or your coordinates in two columns (latitude, longitude)

    In our first example we show reverse geocoding

  4. Open Extensions > Apps Script

    • You will be prompted to give the script permission to run. You will need to select "Continue".
    • A popup will appear asking you which Google account you want to authorise. Select one.
    • The popup will display a warning that our app isn't verified. Click "Advanded"
    • Scroll down and then click on the link to "Go to your-project-name (unsafe)"
    • Now you will need to give the project access to your spreadsheets. Click "Allow"
    • A popup will appear in your spreadsheet asking your for your OpenCage API key. Enter it and click "Geocode"

Forward geocoding is very similar:

  1. Follow steps 1-5 above
  2. Create three columns, the first column should contain the address
