const geojson = parseToGeojson(fileContentToParse)

//This will show the result, manage as needed
console.log(JSON.stringify(geojson))

Example

import { parseToGeojson } from 'openair-geojson'

const fileContentToParse = '*## Castellón CTR ###

const geojson = parseToGeojson(fileContentToParse)

//This will show the result, manage as needed
console.log(JSON.stringify(geojson))

Result

With the example above using the Castellon CTR airspace, the geojson generated result would look like this:
