scrapper-tools/src/jsonToCsv.ts

Its in development but I use it in all my web automation project.

import AsyncLock from 'async-lock'
let lock = new AsyncLock()
import { Parser } from 'json2csv'

export default async (fields, jsObjects) => {
  return await lock.acquire('jsonToCSV', async () => {
    const parser = new Parser({
      fields,
    })
    return parser.parse(jsObjects)
  })
}
