How to make row unique name in slice in lower case as it always showing all letters in caps

Hello Shrikant,
 
Thank you for posting your question.
 
Do you mean these captions (see attached image)?
If yes, it can be changed via CSS. By default text-transform: uppercase; is used for these captions.
 
Mind that the recommended approach is to add your own CSS in a separate file, without changing the original webdatarocks.css. This will ensure that the updates to the newer versions will be simple and smooth.
