as mentioned I’m probably not the best person to answer this, but I’ll do my best.
The main difference is that organization is a noun and organizing is a verb.
Organization is defined as:
a : the act or process of organizing or of being organized
b : the condition or manner of being organized a group with a high degree of organization
Organizing is defined as:
To form into a coherent unity or functioning whole
So organization is the action of organizing something, while organizing is the action itself. The words are almost interchangeable, except one is a noun and one is a verb.
