Hi all,
hope all is well with everyone and greetings from India community.

I'm sorry if you did know this before, but thought to share them with you. While doing some research regarding Wikitable, I'd found out a tool which works better spreadsheets such as Gnumeric, MS Excel, etc. Find the tool here: http://excel2wiki.net/wikipedia.php

Simple procedures: You need to copy the list available from Internet to Spreadsheets, and then copy the whole excel sheet, paste it there in the link and click on submit. You'll find contents which is ready-to-paste to Wiki. Use this tool for lists with extensive number of monuments, and be careful while using it. 

Thanks! Do let us know if you have any other alternatives :)

Thanks and regards,
Karthik Nadar.
