How do you use Present Perfect and Past Simple?
Hello! Could you help me, please!? This exercise is Present Perfect/Past Simple: Since he has become successful, he has spent a lot of money helping homeless people, and he has written also books about his experience. His story was told in a film.

In the phrase "and he has written also books about his experience" should I use the present perfect? Or would be correct to say "he also wrote books about his experience" ?

Hello! Could you help me, please!? This exercise is Present Perfect/Past Simple:  Since he has become successful, he has spent a lot of money helping homeless people, and he has written also books about his experience. His story was told in a film.

In the phrase "and he has written also books about his experience" should I use the present perfect? Or would be correct to say "he also wrote books about his experience" ?

Answer

No the sentence is correct as it stands except it should be: "he has also written books about his experience." However, the sentence "Since he has become successful....." could be changed to "Since he became successful......"., but both versions are correct.

Answer

From what I know, you can't change Present Perfect to Simple Past because it wasn't specified when the event did happen, there's no time (yesterday, last week...) in this sentence. 
You only use simple past for thing in which you know when it happened.
For instance: " I ate apple yesterday", while on Present Perfect would be 
"I have eaten apple"
