How to process final scrapers result in Scrapy?
You could subclass the JsonItemExporter overwriting the finish_exporting method to process the final json file
Say I am parsing a listing page and generating a JSON output. At the end when all stuff is parsed, I want to run some operations on final scraped result. How can i do it in Scrapy? I know about process_item but it works for each item in iteration. The closed thing I found was close_spider but I am not sure that if I run scrapy crawl  spider whether it will give me JSON I created in closed_spider? If yes then how?
