Hi Suresh,
You can also try below:
Just select your column A and Press Alt+HLN key combination and select option "Use formula to format cell".
write any one of the below formula:
=ISTEXT(A1)=True , and select color to format.
Or
=Type(A1)=2 , and select color to format.
The above will highlight cells containing text.
Now you can apply filter by color as said by Deb.
P.S. Just need favor from Deb to know how to apply filter using color, as honestly speaking, I don't know how to do it.
Thanks & Regards,
Anupam Tiwari
