Overview
I had the opportunity to export registered content from Drupal in CSV format, so here are my notes.
I used the following module.
https://www.drupal.org/project/content_export_csv
Installation
It could be installed using the standard method.
Usage
After installation, navigating to Administration > Content > Content displays the “Export Content” button.

On the next screen, by selecting the content type you want to export, I was able to export a list of content of the specified content type.

Summary
I hope this serves as a useful reference for bulk exporting content from Drupal.
