Export Content from Drupal to WordPress
You may want to try the Forena module (disclosure: I'm a co-maintainer of it) to create a "report" that includes the data that you're interested in. As part of the report design, indicate which export formats you want to allow for exporting the data included in it. Typical export formats that are supported are CSV, XML, HTML, XLS, etc.

Have a look at the Simple Table of States example, and think of it as the equivalent of your "content to be exported". And note the hyperlinks in the upper right, which are:


CSV.
XLS.
HTML.
XML.


Try any of these links to get the equivalent of the extracted information, but in the format you requested (there or other supported formats such as PDF, DOC, JSON, etc).

Checkout Forena's Community Documentation for (way) more details, and/or the documentation that comes with the module.
