I have interfaced my Energy Meter with RS232, and then used a RS232-to-USB-Cable to interface with my PC. My Energy Meter uses Modbus Protocol.
I get readings like these through Modbus Slave / Modbus Poll software. How do I get it in the right format?

You should learn how to footle around on manufacturer websites to find any information which might be even close to what you need. There is a mod bus protocol manual for your meter if you go to Support->Downloads, put a check mark against just Multifunction Meters, and on the listing row RISH EM 1320/30/40 click the right hand link in the column Manuals.
The manual is here: http://www.rishabh.co.in/index.php/products/download/349
That manual seems to give the register addresses you should look at for different values. I obviously can't know what your modbus polling software is actually doing to get the data you posted, you need to make it look at the modbus registers that have the data you are interested in using the manual as a guide. No I don't know any more about your particular meter.
BTW if you had actually tried I'm sure you could have found this yourself.
