Excel Headers with Space, +, & ,-, with these special characters while exporting in process model throwing error.

Hi All,

Currently i am working on requirement where user select some columns on UI and that columns contains Space, +, & ,-, with these special characters. 

Example:

Alpha + Beta

Alpha & Beta

Hello World(y/n)

any many more with special characters. but while exporting data through export to excel plugin when configured above headers name its throwing an error.

Error Message: Either selection or filters are invalid: The alias [Aplha/Beta] cannot be used because it contains illegal characters.  The alias must contain only letters, numbers, and underscores, and must start with a letter. (APNX-1-4505-009)

Is there's any way that we can achieve this piece of functionality.
