Several output formatters are supported:

  • CSV

  • GSA Feed (Google Search Appliance)

  • In Memory (for test purposes mostly)

  • JSON

  • Sitemap

  • XML

  • Excel XML

  • XLSX (SpreadsheetML format for Microsoft Excel)

You may also create your own. To do so, simply create a class that implements the Exporter\Writer\WriterInterface, or better, if you know what Content-Type header should be used along with your output and what format it produces, TypedWriterInterface.
