title: Export entire dataset to file

import ApiLink from '@site/src/components/ApiLink';
import Tabs from '@theme/Tabs';
import TabItem from '@theme/TabItem';
import RunnableCodeBlock from '@site/src/components/RunnableCodeBlock';

import JsonExample from '!!raw-loader!roa-loader!./code_examples/export_entire_dataset_to_file_json.py';
import CsvExample from '!!raw-loader!roa-loader!./code_examples/export_entire_dataset_to_file_csv.py';

This example demonstrates how to use the <ApiLink to="class/BasicCrawler#export_data">`BasicCrawler.export_data`</ApiLink> method of the crawler to export the entire default dataset to a single file. This method supports exporting data in either CSV or JSON format and also accepts additional keyword arguments so you can fine-tune the underlying `json.dump` or `csv.writer` behavior.

:::note

For these examples, we are using the <ApiLink to="class/BeautifulSoupCrawler">`BeautifulSoupCrawler`</ApiLink>. However, the same method is available for other crawlers as well. You can use it in exactly the same way.
