How to convert what appears to be a JSON file to CSV

[NewBeie]

Hi,
I have this file below, the format looks like it's JSON but I'm not sure, I want to convert it to csv.

I have also attached the file for clear readability.

(UserResponse){
UserData =
(UserData){
Entry[] =
(UserData){
Active = True
CreatedTime = 2014-07-05 18:38:59.062000+02:00
FirstName = "System"
Lastname = "Account (AddressBook)"
Locked = False
RoleNames =
(RoleNames){
Entry[] =
"Integration admin"
}
UserName = "User1"
UserOrganisation = "Default Organization"
}
(UserData){
Active = True
CreatedTime = 2014-07-05 18:38:59.062000+02:00
FirstName = "System"
LastLoginExt = 2019-04-13 20:04:03+02:00
Lastname = "Account (ChickenFeet)"
Locked = False
RoleNames =
(RoleNames){
Entry[] =
"Integration admin"
}
UserName = "User5"
UserOrganisation = "Default Organization"
}


}
}
