Stop bumping your question. That is really annoying.
You haven’t posted your code, so how do you expect anyone to give you a meaningful reply?
Also, if you have done a google search on reading excel files in ruby, you would have known of at least two libraries which read Excel files. Please google next time before posting. If you can’t find any results, it does not necessarily mean they don’t exist. It just means you are incapable of looking for what you want.
And that does not mean you spam mailing lists with inane questions.
