The article discusses the process of exporting scraped data in JSON and CSV formats using Node.js. For JSON, it highlights the use of the fs module's writeFile() method, emphasizing the importance of readable formatting. With CSV, it notes the need to structure the data correctly, considering headers and delimiters to ensure consistency. This is particularly important to prevent missing values when objects have varying keys. The article includes examples and a recommendation to utilize third-party packages for easier CSV generation.
The exportToJSON function leverages the fs module to asynchronously write your scraped data array to a scraped-data.json file, making it easy to read.
Exporting data to CSV requires transforming a JavaScript array into structured CSV data, handling delimiters, headers, and ensuring consistent object structure to avoid misalignment.
