convertCSV(fileName: string, data: any | Country[] | City[]): Convert data to CSV format and save it to a file.

import { convertJson, convertCSV } from './convert.ts';

const data = [{ /* Your data here */ }];
convertJson('data.json', data);
convertCSV('data.csv', data);

Data Files

This utility assumes the presence of data files in JSON format. Ensure you have the required data files in the specified locations before using the utility.

There is also csv files of both countries and cities this is to make it easier to import data to any database as the package size is quite large.
