Im using a nodejs code to download a csv file which also contains 19 digits number. But after downloading Im getting a number in the format like "1.23457E+18". So If I try to expand or format this cells to text or number Im getting last 4 digits as 0000. But My actual number is 1234574654345678987. 

        "Unique": jsonResult[i].dcp,

Im assigning like this. If try to add some special characters like 

   "UniqueSysReference": jsonResult[i].dcp + "A",

Then Im getting the original number with A. But I need only the actual number. Im using

"json2csvParser". Can anybody please tell me how to fix this issue?

Javascript cannot handle big numbers and their operations. largest exact integral value is 253-1, or 9007199254740991. In ES6, this is defined as Number.MAX_SAFE_INTEGER.

you can use bignumber.js library https://www.npmjs.com/package/bignumber.js .it handles all operations related to big numbers.

//require it
const BigNumber = require('bignumber.js');

 //then you can convert your number to bignumber
    Unique": BigNumber(jsonResult[i].dcp)

  //if you want to show that big number as string
  console.log(BigNumber(jsonResult[i].dcp).toFixed())
