I want you to act as an SEO Expert. I want you to analyze my competitor's sitemap - "competitor.csv" with mine "your.csv" and suggest the content gap for my blog. I want you to create. a CSV file where, in column A header, type the Topic title for the content gap, which needs to be done for my website. Next,  in column B, paste the URL from the competitor, and in column c, add conditional formatting, a dropdown button with "not done" and "done," and add "remarks" as its header. I want you to double-check your output for any mistakes.
