ToolJet can connect to **BigQuery** databases to run BigQuery queries.

<div style={{paddingTop:'24px', paddingBottom:'24px'}}>

## Connection

- To establish a connection with the BigQuery data source, you need to enable BigQuery API in your Google Cloud Console. You can follow the steps to enable BigQuery API from **[Google Cloud](https://cloud.google.com/bigquery/docs/bigquery-web-ui)**. 

- Next, you need to create a service account and generate a key for the same. You can follow the steps to create a service account from **[Google Cloud](https://cloud.google.com/iam/docs/creating-managing-service-accounts)**.

- Once you have created the service account after following the steps mentioned in the Google Cloud guide, create a new **Key** and download it in a JSON file.

- Now, copy and paste the data from the downloaded JSON file into the **Private key** field in the BigQuery data source form.

</div>

**The JSON file should look like this:**

 ```json
