The fs module doesn't understand file formats, it just reads buffers. Optionally it can convert the buffers into strings. As for that file, it's a csv just with | instead of ,.

Parsing it is somethings like:

// split the lines into rows
const rows = raw.split('\n');
// split into columns
const data = rows.map(row => row.split('|'));

The empties will just be empty strings in the row arrays. You can filter them out. rows.map(row => row.split('|').filter(el => el !== '')) but most likely you'll want to leave them in for easy access my index.

But that assumes there are no escapes or other irregularities. I recommend finding a csv module from npm.
