please help, I want to make an export data in the form of an xls file and it will be sent to an email so that it can be downloaded.
I use grails, groovy
The question is a tad too generic for the stackoverflow format. I.e. you are essentially asking the community to solve the whole problem for you without prior work by you.
With that said, for email I would use something like:
http://www.simplejavamail.org/
and for generating the xls file I would use apache poi.
I.e. these are libraries you would need to add as dependencies to your project and they would help you with your task.

Can any one suggest me any library in javascript(client end) document editor where user can view and edit the documents like doc, docx, odf etc.
I have tried webodf but it doesn't support doc/docx. Also, it's not getting implemented properly as editor.
Any suggestions are welcome.
Your best bet is to look for converters, and then edit the converted content.
I've been looking for a working solution now for a couple of weeks, and the best I've found to date is docx2html.
Depending on your development platform you might also want to Google 'ONLYOFFICE Document Server Community Edition'. They have in page editors for Word, Excel and Powerpoint - but they're asp. It's an open source platform and available on Github. Might be worth a look though.

Getting started with Orchard 1.5.1, I follow the tutorial provided here:
http://docs.orchardproject.net/Documentation/Navigation-and-menus
and found that the Interface in the tutorial is different from that of 1.5.1 version, and I could not find how to sort menu elements or how to add URLs for these elements.
Navigation has changed since version 1.5:

You can sort items with drag & drop…

Are there any markdown editors that integrate with rails (eg in a gem) and offer live preview?
Checkout markdown.js and showdown. You could rig them up to parse whatever the markdown input is whenever certain events fire (i.e. a user releasing a key when typing in the markdown textarea). I'm not aware of any other embeddable markdown editors with live previews, but it seems it would be easy enough to make one with one of these libraries.
Check out the gem below, its not well documented but seems to work

I want to work on personal project working with books and magazines. I was wondering if there were any APIs for the EPUB standard. That are open to the public.
Please and thank you
GC
Don't know of any freestanding API as such, but FBReader supports EPUB so it might be worth looking through the sources of that and see if you might be able to extract the EPUB bits easily.
It depends on what you need the API to do for you. Create books, parse books, mine text in books? I'm confused as to why you would mark as correct an answer which points to a reader--how could that help? You are probably looking for things such as https://code.google.com/p/python-epub-builder/.
