# Adding data sources in bulk

Add multiple data sources at one time in the Pentaho Data Mastering by importing a JSON file that contains all the information for the data sources.

Perform the following steps to create multiple data sources at one time:

1. On the left navigation menu, click **Master Data**. The **Master Data** page opens.
2. In the **Resources** card, click **Data Sources**.

   The Data Sources page opens.
3. Click **Add Data Source** and select **Import Data Source(s)**.

   The Import Data Source(s) dialog box opens.
4. Browse to and select the JSON file that contains the data sources information to import.

   **Tip:** You can drag and drop the JSON file into the Import Data Source(s) dialog box.
5. Click **Continue**.

   A confirmation message is shown in the top-right corner of the page and the new data sources are added to the data source table.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.pentaho.com/pentaho-data-mastering/sourcing-data/adding-a-data-source/adding-data-sources-in-bulk.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
