Question: Is there a service that allows me to export comments from Instagram, Facebook, and Twitter into a spreadsheet?

If you want to export comments from Instagram, Facebook and Twitter into a spreadsheet, EasyComment is a good choice. The service is geared for social media influencers and content creators, with features like comment export to CSV or Excel files, filtering and comment data analysis. It's free to use and doesn't require registration, so it's a convenient way to manage and analyze your social media comments.

Another option is Browse AI. Although it's primarily an information retrieval system for web data, it can extract specific data from social media sites like Instagram, Facebook and Twitter, presenting the results in a spreadsheet. It also can schedule searches and send alerts when data changes, which can be useful for monitoring comments and other social media activity over time.
