What do I need to know in order to display Excel data in an HTML table?

Question

I'd love some guidance here guys...

If I were to create a website that would display data from an Excel sheet (that would be updated regularly) in an HTML table, what languages do I need to know?

I want to make a site as user-friendly as possible, therefore I want to create something that does the 'hard work'.

Format would be this: user submits data, spreadsheet updates, webpage table updated accordingly, up-to-date page visible to all.

Thanks in advance.

Thanks for all the links.

During my own research, I had already come across most of them, but I wasn't really able to understand them fully, due to my lack of knowledge in the whole subject.

Will JavaScript be enough to do all of the things in the website I described? Is there any clarification you need in order to answer?

Thanks again.
