Create a Page view which shows content.
Select the fields you want to see for the node like nid, title, author, etc.
Add Author as a filter and expose this field so that you can provide user id or username via the exposed filter form.
Save the view.
The page view should now work on the URL you provided in step 1. Here once you provide a username or user id (depending on which field you exposed) the content should get filtered.
Add a module like views_data_export, which allows you to export the list in a file.

Unable to install GeSHi Filter, geshifilter.settings already exists in active configuration

num contentor com o drupal depois de instalar e reinstalar o módulo com o composer surgiu o seguinte erro:

Unable to install GeSHi Filter, geshifilter.settings already exists in active configuration.

para resolver o problema bastaria remover as configurações do módulo com:
drush config-delete geshifilter.settings

como o drupal está a correr numa stack com o docker (drupal4docker) utilizaremos, dentro da pasta onde está definida a stack:
make drush config-delete geshifilter.settings
