ToolJet can connect to **Cloud Firestore** databases to read and write data.

## Connection

To establish a connection with the **Cloud Firestore** 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 Cloud Firestore as the data source.

ToolJet requires the following to connect to your BigQuery:

For generating a private key check out **[Firestore's official documentation](https://cloud.google.com/iam/docs/creating-managing-service-account-keys#iam-service-account-keys-create-console)**.

## Transforming Firestore Query Result for Table Widget

The Firestore query result is in the form of object so we’ll need to transform it into array.

```js
return (data = Array(data));
```
