# BigQuery

ToolJet can connect to BigQuery databases to run BigQuery queries.

## Connection

To connect to BigQuery, you need to enable BigQuery API in your Google Cloud Console. You can follow the steps to enable BigQuery API from [this link](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 [this link](https://cloud.google.com/iam/docs/creating-managing-service-accounts).

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

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

 ```json

  "type": "service_account",
  "project_id": "tooljet-279812",
  "private_key_id": "ea6e234sdfsdf3242b91525626edeef74a14e58761",
