Here is how I do simple JSON:

Serial output directly into NodeRED - Arduino for STM32 (stm32duino.com)

No JSON library needed.

You could also write a little utility to read an SD card and spit JSON out serially.

Oh, welcome!

I need just make it in JSON form exemple

{
    "Weight": 55.65 ,
    "Rate": 50,
    "PosX": 70,
    "PosY" : 69.63
   
 },
{
    "Weight": 75.15 ,
    "Rate": 55,
    "PosX": 25,
    "PosY" : 69.0

 },
 {
     "Weight":111.15 ,
    "Rate": 22,
    "PosX": 34.12,
    "PosY" : 10.1,

  },
 {
     "Weight": 150.15 ,
    "Rate": 60.42,
    "PosX": 34.12,
    "PosY" :10.11,
   }
