I may be overcomplicating things.
I have an array of URLs (extracted from a website’s sitemap) and a second array of URLs (extracted from a Google Search Console export in Google Sheets).
I want to find a list (array?) of URLs that exist in the Google Sheet but don’t exist in the sitemap.
My idea at the moment would be to iterate through the URLs from the Google Sheet and each time ask “does with URL exist in the sitemap URLs?” - but I don’t know how to do that.
Any ideas?
