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

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

## Connection

To establish a connection with the **BigQuery** data source, you can either click on the **+ Add new Data source** button located on the query panel or navigate to the **[Data Sources](/docs/data-sources/overview)** page from the ToolJet dashboard and choose BigQuery as the data source.

ToolJet requires the following to connect to your BigQuery:
- **Private key**

How to get a Private key?
1. 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)**. 
2. 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)**.
3. 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.
4. 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:**

  "type": "service_account",
