Solution 1

One quite simple way would be to use Interop and using Evaluate[^] method check what is the return value of the evaluate. If it returns an error, then the formula is invalid.

Thanks for quick response.

Can we do same using OpenOffice or any another option it should be open source.
Actually I'm not using MSOffice

Unfortunately I don't know OpenOffice well enough. I know they have a SDK so perhaps something similar exists. The main idea is still to simply set the formula and check if error is raised...
