Inspecting memory on the field

I instrumented one of my system with a low-level memory read functionality. I'm able to read the content of a memory block in a running system by remote.
I also have the source code and build files of the firmware running in the system.
Now suppose you have a complex static data structure at address X. Its size is 1000 bytes. The struct could be defined as:
--- mystruct.c ---
#include "object1.h"
#include "object2.h"
static struct {
   int x;
   int y;
   struct {
     enum { OBJ1, OBJ2 } type;
     union {
       object1 obj1; // object1 is another struct
       object2 obj2; // object2 is another struct
     };
   } array[10];
   ...
} mystruct;
---
By using low-level memory read function, I can read the current values of all the bytes in mystruct. How to print a nice report of mystruct values, such as:
mystruct = {
   x = 10,
   y = 3,
   array = [
     { OBJ1, obj={...}, obj2={...} },
     { OBJ1, obj={...}, obj2={...} },
     { OBJ1, obj={...}, obj2={...} },
     { OBJ1, obj={...}, obj2={...} },
   ]
}
I know I can write a script that works on a specific mystruct, maybe calculating the offset address of each field. I'm searching for a tool that can calculate the correct offset address and print a nice report as before.
