Excel Table + Images >>> Polished HTML Report

Hello!)

I need you to help me decide what is the best way to distribute daily technical reports.

I have a report in the excel format which contains of 5 sections with no images (each section is on a separate tab). Each section has 5 large charts assigned to it and which are stored separately.

I need to be able to present this information to my users online.

I have for now two options of doing this:

[LIST=1]
[*]export separate sheets of the excel report into separate HTML files – embed those into a single HTML file in Dreamweaver and include the external images so that everything is presented in a single large HTML page.
[/LIST]

[LIST=1]
[*]Link separate sections of the report and the images to an indesign document so that all of these are placed on their own single page. Export the whole report as a PDF file.
[/LIST]

I wish to present this report in a closed, password protected section of my website to a few of my clients. Which do you think of the above two ways is the best to present these reports?

I am concerned with the ease of sharing the PDF files online but of course someone can print a webpage to PDF if they like and do that as well.

I will be happy to hear any opinion!
