You really need to tell us more about the problem, and even then it's unlikely we will do more than point you at a bunch of modules. This is likely to be a rather non-trivial problem because Excel graphs are not a common browser supported object type. If you have the opportunity to massage the data on a PC then you could export the graphs as a suitable image type. Otherwise, most likely, you will need to recreate the graphs from the original data using a suitable charting module. In any case the devil is in the details and you have not given us any details.
