This example demonstrates how to store extracted data into datasets using the <ApiLink to="class/PushDataFunction#open">`context.push_data`</ApiLink> helper function. If the specified dataset does not already exist, it will be created automatically. Additionally, you can save data to custom datasets by providing `dataset_id` or `dataset_name` parameters to the <ApiLink to="class/PushDataFunction#open">`push_data`</ApiLink> function.

        <RunnableCodeBlock className="language-python" language="python">
            {BeautifulSoupExample}
        </RunnableCodeBlock>
    </TabItem>
    <TabItem value="PlaywrightCrawler" label="PlaywrightCrawler">

    </TabItem>
</Tabs>

Each item in the dataset will be stored in its own file within the following directory:

```text
{PROJECT_FOLDER}/storage/datasets/default/
```

For more control, you can also open a dataset manually using the asynchronous constructor <ApiLink to="class/Dataset#open">`Dataset.open`</ApiLink>
