how to add customized fields before saving the data to json

I have a simple python program which converts excel to json .

import  jpype     
import  asposecells     
jpype.startJVM() 
from asposecells.api import Workbook
workbook = Workbook("sample.xlsx")
workbook.save("sample3.json")
jpype.shutdownJVM()

And i get the output as below

[
 {
  "Name": "DS",
  "Gender": "M"
 },
{
  "Name": "DS1",
  "Gender": "M"
 },
]

Instead i want the output to have some extra (hardcoded) fields and word data appended

[
 {
  "date": "06/05/2022",
  "data":{
    "Name": "DS",
    "Gender": "M"
    }
 },
 {
  "date": "06/05/2022",
  "data":{
   "Name": "DS1",
   "Gender": "M"
  }
 },
]

Any insights on aspose-cells ? i referred the aspose docs , but didnt find anyways to do it. Any help will be appreciated. Thanks in advance.
