The article explains how to export scraped data in JSON and CSV formats using Node.js. For JSON, the fs.writeFile() method writes data to a file, and formatting with JSON.stringify enhances readability. For CSV, a structured approach is necessary, as inconsistent object keys could cause misalignment in the output. Therefore, it's crucial to define headers when exporting to CSV to prevent data issues. The article also emphasizes the usability of exported files across different platforms and applications.
The exportToJSON function leverages the fs module to asynchronously write your scraped data array to a scraped-data.json file, enhancing readability with indentation.
Exporting data to CSV requires transforming JavaScript arrays into structured CSV data, which means managing delimiters, headers, and ensuring consistent object structure.
