Copying and Pasting Content in to WordPress

I have a current website at [login to view URL] that I want to transition to WordPress. I have developed a script that will export the content that needs to by copied-and-pasted into WordPress posts. There are approximately 1,200 posts that will need to be created. The content provided will relay specific instructions as to what needs to be entered where in WordPress. For example: <!-- Start Brand Content --!> Title: Aldo Content: This is content about the Aldo brand. This content will contain some HTML code. Categories: Shoes, Mens, Womens, Childrens <!-- End Brand Content --!> You may see a more detailed sample of the content you'll be using here: <[login to view URL]> Please email me with any questions. Thanks.
