Looker API for Google Sheets

This Google Apps Script uses Looker API to load Looks, get data dictionaries, etc.

Install

  • Save the script in the script editor (Tools > Script Editor)
  • Refresh your Sheet, you should now have a "Looker API Credentials" menu on top.
  • Click the menu and set your base URL, client id and client secret

Important Note: these are stored on the spreadsheet environment, anyone with access to the sheet will be able to use them. Switch to userProperties to make them user specific. This might break the formulas for users without API creds.

  • Go back to your spreadsheet, you can now use the custom formulas listed below

How to use

=LOOKER_RUN_LOOK(1789, 1, 10000)

  • Return the results of a saved Look in csv (1) or the raw SQL (2). The third parameter is the query limit.
    • Look ID (required)
    • Format (optional), 1 (results), 2 (SQL). Default value is 1 (results)
    • Query limit (optional), Default value is 5000. -1 for no limit.

=LOOKER_GET_LOOKS_BY_USER(123)

  • Return all Looks from the user

=LOOKER_GET_LOOKS_BY_SPACE(456)

  • Return all Looks within the given space

=LOOKER_GET_LOOKS_BY_DASHBOARD(789)

  • Return all Looks on a dashboard

=LOOKER_GET_EXPLORES("model_name")

  • Return all Explores within the given model

=LOOKER_GET_DATA_DICTIONARY("model_name")

  • Return all dimensions and measures within all Explores within the given model

=LOOKER_GET_USERS()

  • Return Looker users

Creating new users

This currently lives in a separate file. The custom function takes an email address and creates a new user, unless the user already exists. The function returns the Looker setup URL, for the user to add details and set a password. The script can be easily expanded to include e.g. a mail merge, to automatically send an email with the setup URL to the new user.

=CREATE_LOOKER_USER(email_address, roles)

  • script in a separate file, creates new users with their email and (optional) assigned roles, returns setup URL for new users. For example =CREATE_LOOKER_USER("brecht@looker.com", "1,2").

Adding other formulas

Looker's API is extensive and only a handful of endpoints are used here. You use other endpoints using UrlFetchApp (docs).

For example:

function LOOKER_OTHER_ENDPOINT(input) {

  var options = {
        "method": "get",
        "headers": {
            "Authorization": "token " + token
        }
    };

    var response = UrlFetchApp.fetch("https://yourcompany.looker.com:19999/this/that" + input, options);

    return Utilities.parseCsv(response.getContentText())
  }
