The article discusses the process of exporting data in two formats: JSON and CSV using Node.js. For JSON, the fs module's writeFile() method is utilized to save scraped data asynchronously into a file, with an emphasis on making the output readable with indentation. In contrast, exporting to CSV requires transforming JavaScript arrays into a structured format while addressing potential discrepancies due to varying object keys. The article highlights the importance of maintaining a consistent structure to avoid data misalignment in CSV files.
When exporting data to CSV, it's crucial to ensure that the structure is consistent across all objects to prevent misalignment or missing values.
During the export process, using the fs.writeFile() method allows for easily saving scraped data in a readable format with proper indentation.
