Exporting Date-Times in Iso Format

I want to export date/time values to JSON formatted as ISO 8601 values

My current script:

const XLSX = require('xlsx');
...
const file = XLSX.readFile(path,{cellDates:true, cellNF:false});
for (sheet in file.Sheets){
     //remove prerendered values, otherwise dateNF is ignored
     for (cellref in sheet){
         const c = sheet[cellref];
         if(c.t==="d"){
             delete c.w;
             delete c.z; 
         }
    }
   const format = "YYYY-MM-DD hh:mm:ss";
   //const format = "YYYY-MM-DDThh:mm:ss"; throws exception as it doesn't recognize T
   const data = XLSX.utils.sheet_to_json(sheet, {header: 1, dateNF:format});
   .....
}

The cells itself already contain the correct datetime inside the v(alue) attribute.

I suggest an option like XLSX.utils.sheet_to_json(sheet, {header: 1, ExportDatesAsISO:true});

Test data: datum.xlsx

This script would work for me but feels just wrong:

const XLSX = require('xlsx');
...
const file = XLSX.readFile(path,{cellDates:true});
for (sheet in file.Sheets){
     for (cellref in sheet){
         const c = sheet[cellref];
         if(c.t==="d"){
             c.w = c.v;
         }
    }
   const data = XLSX.utils.sheet_to_json(sheet, {header: 1});
   .....
}
