        fileAsArray: true,
        returnAsString: []

    async function myFunction() {
        const myCsvFileData = await parseCsv('C:\\path\\to\\my\\file.csv', defaultOptions );
        const otherCsvFileData = await parseCsv('C:\\path\\to\\other\\file.csv', options2 );
        // Use the data however you'd like
    };

    const myOtherFunction = async () => {
        const myCsvFileData = await parseCsv('C:\\path\\to\\my\\file.csv', defaultOptions );
        const otherCsvFileData = await parseCsv('C:\\path\\to\\other\\file.csv', options2 );
        // Use the data however you'd like
