Loading Data with Google Drive Extractor

In the previous step, you learned how to quickly load data into KBC using manual import. In real production projects, this is seldom used as most of the data is obtained automatically using extractors. In this part of the tutorial, you will use a Google Drive extractor to load data from an external data sheet.

Google Drive is a common method for sharing small reference tables between different organizations. For our purposes, create a Google spreadsheet from the level.csv file. Let’s pretend someone shared the level table with you through Google Drive.


Go to Google Spreadsheets and Start a new Blank Spreadsheet. Then go to File - Open and Upload the level.csv file.

Configure Google Drive Extractor

Go to Extractors in KBC and click the New extractor button:

Use the search box to find the Google Drive extractor.

Each KBC extractor can have multiple configurations. This concept allows you to extract data from, for example, multiple Google accounts. So far, there are no configurations of the Google Drive Extractor.

Click on Create New Configuration and name the new configuration User Levels; the file we want to extract contains the seniority level of each user.

Then authorize the extractor to access the spreadsheet by clicking the Authorize Google Account button.

Google Drive Configuration Start

There are two basic authorization options: Instant Authorization and External Authorization. The latter is useful when someone wants to share their document with you without sharing their account directly. Use Instant Authorization now.

Google Drive Authorization Start

On the following screen, click Allow.

Google Drive Authorization End

Now you want to select the Google Drive files to import.

To select the files you want to import into the authorized extractor, you need to temporarily elevate the authorization so that the extractor can access your sheets.

On the following screen, click Allow.

Find and select your spreadsheet document named level.

Google Drive Selected Document

Then select the individual sheet. Our ‘level’ document contains only one ‘level’ sheet, so select that one. It will appear on the right side of the screen as one of the Sheets to Be Added to Project.

Google Drive Selected Documents

When you Save changes, you should obtain a result like the one below. Then, click on the Run Extraction command on the right. This will create a background job extracting the selected sheet from the Google Drive document and loading it into Storage.

When a job is running, a small orange circle appears under Last runs, along with RunId and other info on the job. Green is for success, red for failure. Click on the indicator, or the info next to it for more details.

Google Drive Results

The extractor automatically creates an output bucket and a table; here it is in.c-keboola-ex-google-drive-user-levels-11.level-level. Click on the name of the output table to check its contents.

This concludes our example setup of the Google Drive extractor.

If you want to use the table created in this side-step in the rest of the tutorial, you have two options:

  1. Replace in.c-tutorial.level with in.c-ex-google-drive-userlevels.0-level in the following steps of the tutorial.
  2. Ensure this table is accessible under the in.c-tutorial.level name using an alias table, as described below.

Creating an Alias Table

First, go to Storage and delete the table in.c-tutorial.level you manually loaded in the first part of the tutorial.

Then create a new Alias Table. It behaves like a Database View as it does not contain any data. It is simply a link to already existing data.

In the configuration popup, select the in.c-keboola-ex-google-drive-user-level-11.level-level table as the Source Table and write level as the alias Name.
