Scrapy provides various data export formats, including JSON, JSON Lines, CSV, XML, and more. Developers can specify output files and formats through command line parameters -o or -O, for example scrapy crawl myspider -o output.json. JSON Lines format has one JSON object per line, which is suitable for handling large amounts of data. CSV format is suitable for tabular data and can be opened directly in Excel. XML format is suitable for scenarios that require integration with other systems. Scrapy also supports exporter extensions, allowing custom export formats or additional export functionality. For more complex data storage needs, pipelines can be used to save data to databases such as MySQL, MongoDB, PostgreSQL, etc. Scrapy's data export functionality makes it easy to use crawled data for subsequent data analysis, machine learning, or other applications. Developers can choose the appropriate export format and storage method based on project requirements.
