If you're concerned about implementation effort you can try the validation bot available with Mx10. That functionality auto generates your validation microflow. Go to the new edit page, right click on the "save" button and click on "Generate validation microflow".

Hi Mukesh,

You need to check each field one by one, there's nothing such as bulk validate.

Hope this answers your question!

If you are concerned about readability, You can abstract few conditions to a Rule. That makes it more readable.
