Breaking functions down in Nodejs - node.js

Question

In my attempt to become a better developer I'm trying to refactor the below Node code into 2 (or even 3) separate functions.
The code simply takes in a file, parses some of the data, and rewrites the parsed data to another file.
So my question is, can the code below be broken down to 2 functions (one function to read and parse, the other to write)? Can it be broken down even further to 3 functions (one to read and parse, one to write, one that calls the other two)?
I have attempted to refactor the code into 2 functions but am not having any luck
const neatCsv = require('neat-csv');;
const fs = require('fs');
const ObjectsToCsv = require('objects-to-csv');
fs.readFile('./someFile.csv', async (err, data) => {
if (err) {
console.error(err);
return;
}
const neat = await neatCsv(data);
const sortArray = neat.filter((obj) => obj.Type !== 'Name');
const priceSortArray = sortArray.filter((obj) => +obj.Price > 5);
const filterSortArray = priceSortArray.sort((a,b) => parseFloat(b.IV) - parseFloat(a.IV));
(async () => {
const csv = new ObjectsToCsv(filterSortArray);
// Save to file:
await csv.toDisk('./someOtherFile.csv');
})();
});

Please try below approach. I hope this is asked by you.
const neatCsv = require('neat-csv');;
const fs = require('fs');
const ObjectsToCsv = require('objects-to-csv');
const readFile = (filePath) => {
fs.readFile('./someFile.csv', async (err, data) => {
if (err) {
console.error(err);
return;
};
const neat = await neatCsv(data);
const sortArray = neat.filter((obj) => obj.Type !== 'Name');
const priceSortArray = sortArray.filter((obj) => +obj.Price > 5);
const filterSortArray = priceSortArray.sort((a,b) => parseFloat(b.IV) - parseFloat(a.IV));
saveFile(filterSortArray);
});
}
const saveFile = (filterSortArray) => {
const csv = new ObjectsToCsv(filterSortArray);
// Save to file:
await csv.toDisk('./someOtherFile.csv');
}
readFile();
