I have a website that I want to move to Drupal 7. It is in HTML. I want the content to be in nodes. I don't know much about Drupal and so I need help doing this. I don't want to create a new theme because I want the design to change. I just want the content in nodes. How can I do this in Drupal? Is there a module that can help?
You don't necessarily need a module to add a content to drupal. Just simply create a content of type page and add your content. To help you with formatting, you may want to install the WYSIWYG module to help you with formatting.
The module I used (several years ago) was the Import HTML module. I imported a site into Drupal 5 and it worked well. There is a Drupal 7 dev version, but I have no experience with it.
If you use it, plan and prepare well, and you can expect a considerable amount of manual editing after the fact. You may have to try a few times before you get it right, but for a bulk import, it saved me a lot of work.
