Step #2: Paste a tweet URL and click + Add to Export List. Repeat for every tweet you want to include.
Step #3: Click Export Retweeters and confirm.
Option 2: Use an account's recent tweets
Step #1: Open Essential Toolbox > Export Tools > Export Accounts Who Retweeted a Tweet(s) or User(s) and select the Bulk export retweeters of a user's tweets tab.
Step #2: Enter any public X username and click Get Tweets with Retweet Counts. Follow the steps on the screen to load up to the account's 3,200 most recent tweets with their retweet counts.

Step #3: All loaded tweets are selected by default. Use the filters to keep only the tweets you want, then export the retweeters.
Your export file
The CSV file lists every retweeter once. The RepostCount column shows how many of the selected tweets each account retweeted, which helps you find the accounts that share your content most often. When the file is ready, you can download it from your Circleboom account, and the link is also sent to your email address.
You can learn more on the Export Retweeters page.
