I am trying to create a wrapper class to hold the JSON response in my apex class. But I am getting the error ' Inner types are not allowed to have inner types '. Below is my wrapper class.

public class GetTheDetails {

// Wrapper class

public class fromJSON{
    public String SId;  
    public List<valueRanges> valueRanges ;
    public class valueRanges {
        public String range;    
        public String majorDimension;   
        public List<values> values;
    }
    public class values {
        public String Id;           //Id
        public String AccountID;    //AccountId
        public String CreatedById;  //CreatedById
        public String Name;         //Name
        public String StageName;    //StageName
        public String CloseDate;    //CloseDate
    }
    public fromJSON parse(String json){
        return (fromJSON) System.JSON.deserialize(json, fromJSON.class);
    }
    
} }

Can anybody help me in identifying the error ? I am not able to find any syntax error in defining wrapper class here.

You need to move the definition of ValueRanges outside of the fromJSON class (same as you have for values).

So your code should be something like:

public class GetTheDetails {

  // Wrapper class
  public class fromJSON {
    public String SId;  
    public List<valueRanges> valueRanges ;
  }

  public class values {
    public String Id;           //Id
    public String AccountID;    //AccountId
    public String CreatedById;  //CreatedById
    public String Name;         //Name
    public String StageName;    //StageName
    public String CloseDate;    //CloseDate
  }

  public class valueRanges {
    public String range;    
    public String majorDimension;   
    public List<values> values;
  }
    
   public fromJSON parse(String json) {
     return (fromJSON) System.JSON.deserialize(json, fromJSON.class);
   }
    
}
