Gaussview Tutorial: How to Load Chemdraw 2D structures in Gaussview 

Yes, you can save it in MDL SDfile (sdf) format. Then you can open it in Gaussview and use the clean tool.

@@mdwithgourav9263 Did it the way you suggested. Then I cleaned and symmetrized the compound in gaussview and saved it in mol format for energy minimization in Gabedit which worked too. But when I try to open the energy minimized file(mol) in gaussview it says 'Failure reading molecules from MDL file'

@@nusaibanazrul9885 I don't think an optimized geometry file from software other than Gaussian will open in Gaussview.

Yes
