Batch Script to generate HTML pages with Macros

We have a html page of a website that has 6 keyword areas in the code that need to be generated based on a batch of 400 keywords. Therefore, keywords 123456 needs to be inserted into: 1. Title Tag 2. Meta Tag 3. Content Area 1 and Area 2 4. Meta Keywords 5. Meta Description 6. File Name The rest of the page stays the same, only the place where we want it changed. This place remains the same and must auto generate 400 pages based on the different keywords. Its really basic.
