Retrieving documents in HTML format

We have the requirement to open multiple stored documents and combine them into a single presentation page.

to explain further, we can have multiple stored douments in multiple formates (i.e. word, excel, text etc). the user gets a screen listing all the documents and can select multiple documents and then open them together.

We can get to the binary of the documents but we are not sure how to convert the binary to ASCII or HTML.

The jist of the processing would be:

1) get the binary of the documents

2) append the ascii or html of each document together

3) display the appended documents in a page

Any help in this matter would be greatly appreciated.
