The process of exporting data in various formats involves utilizing Node.js's filesystem module. For JSON, the exportToJSON function uses fs.writeFile() to write scraped data into a JSON file, making data inspection straightforward. For CSV, the process requires transforming a JavaScript array into a structured format while managing delimiters and headers. Inconsistent object keys can complicate CSV exports, necessitating the explicit definition of headers to ensure proper alignment of values.
The exportToJSON function leverages the fs module to asynchronously write your scraped data array to a scraped-data.json file.
Exporting data to CSV requires transforming JavaScript arrays into structured CSV data while handling delimiters, headers, and edge cases.
CSV files depend on consistent object structures, as varying object keys can lead to missing or misaligned values in exported CSV.
To solve the problem of inconsistencies with data containing varying keys, explicitly stating the required headers is essential.
