Hi,

I would suggest using the trim() function followed by a regex replacement using replaceAll() that matches instances of the space characters i.e. (\\s+) and replaces them with a single space. 
Example:

String str = ' how is the weather today '; str = str.trim(); str = str.replaceAll('(\\s+)', ' '); return 

str;

Hope this helps.

Kindly mark this as solved if the reply was helpful.

Thanks,
Nagendra

Hi Nagendra
sorry I did not phrase question properly

Inside the controller of lightning component the data is coming from api call.
pCodeShortDesc = pCodeShortDesc.subtring(0,28);

this return a string like "Nebuent    Inh 300 mg"

Now in UI, when I hover (i.e keep the mouse) it shows as Nebuent    Inh 300 mg

I debugged and saw that value from api call is Nebuent Inh 300 mg  but I dnot udnerstand when I hover it shows Nebuent    Inh 300 mg

please help me out very earliest
