Exporting to a CSV file with Javascript

I would like to create a CSV file through a form script, as it will be much quicker/more automated than going through the File/Export/Export option.

I have been able to create a script which uses Utils.copyTextToClipboard() to get the data out (and then using the clipboard to insert it into an AppleScript). It appears to work, but was wondering whether it is also possible to write the data to a file rather than the clipboard?

The script as far as I have got with it:

var client_name = record.getFieldValue('fld-ffa7651ff5bd48a9aa8184a69be8550e');
var email = record.getFieldValue('fld-152d99920304499f8f89c3868eb144d1');
var details = record.getFieldValue('fld-23c8168c1deb45bfbcabc862ad6e5199');
var date_prescribed_information_provided = record.getFieldValue('fld-0bf58a5d40b3430f8745b86b2a49775a');
var document_details = record.getFieldValue('fld-b8a4b0731dc94f46abf28eab828abc4e');
var number_of_documents = record.getFieldValue('fld-7ba7df82977945988aac2598dc528a75');
var amount_of_notary_charge = record.getFieldValue('fld-648fee2d0eaa4e7d973fe86bde1d504f');
var what_will_third_parties_be_providing = record.getFieldValue('fld-abfb6ffd2c7c4695972ed54ec463fc08');
var third_party_charge_plus_charge_to_arrange = record.getFieldValue('fld-8cc4031614d7402aa5e131d33ae1c039');
var final_charge = record.getFieldValue('fld-6b86691517dc4b8b8efa63b7da98185d');
var second_individual_client_name = record.getFieldValue('fld-772ee93b5eb747d294e5a9a7b548ebda');
var second_individual_email = record.getFieldValue('fld-d09998df75864a0e8f82b6f61188b537');

// set email for prescribed information document

if (second_individual_client_name){
var email_for_prescribed_information = email + " and " + second_individual_email;
} else {
var email_for_prescribed_information = email;
}

var date_formatted = date_prescribed_information_provided.toLocaleDateString("en-GB", { year: 'numeric', month: 'long', day: 'numeric' });

var lines = client_name + ";" + email_for_prescribed_information + ";" + details  + ";" + date_formatted + ";" + document_details + ";" + number_of_documents + ";" + amount_of_notary_charge + ";" + what_will_third_parties_be_providing + ";" + third_party_charge_plus_charge_to_arrange + ";" + final_charge + ";" + second_individual_client_name + ";" + second_individual_email;

//	Utils.copyTextToClipboard(JSON.stringify(record.first_name_id));
	
Utils.copyTextToClipboard(lines);
