Change Document Format

I need to format the information of an excel file(Source File) to a different format(Result_File). The data won't change from source to result is just the format of the data. The most important restriction is. IT must fit in one standard letter page. It must be written in PHP or JAVA and it must be well commented. This needs to be able to be run with different data values Do not code just for this 2 specific files. The data values will change every week when i get a new source file.
