Old accounts show up
The tool may be comparing old relationship records instead of current followers.
Instagram list comparison
Compare list website not working for your Instagram export?
Generic list diff tools work only after you extract clean usernames. If you paste raw Instagram JSON or HTML, the output can include stale accounts, wrong counts, or usernames from the wrong relationship file.

Short answer
A compare-list website is still fine for two clean text lists. It is not reliable as a raw Instagram export parser. First extract normalized usernames from the Followers and following files, then compare.
Counts do not match
Raw export files can include nested objects, timestamps, and separate relationship lists.
Chat tools disagree
A model can summarize or truncate large exports before doing the actual comparison.
The followers file looks missing
Some exports are incomplete or requested with the wrong data category selected.
Got your Instagram ZIP already?
Upload it to Unfollio and see who does not follow back without entering your Instagram password. Your ZIP is read in your browser, and saved audit history is optional.
Compare normalized usernames, not export files.
Unfollio reads the official Instagram export, checks that the Followers and following data is present, normalizes usernames, and saves snapshots so later exports can reveal exact changes. For a product-focused version, see compare Instagram followers and following.
- 01Request Followers and following from Instagram Accounts Center.
- 02Choose JSON if available, and keep the original ZIP file.
- 03Parse the export into clean followers and following username lists.
- 04Compare the current followers list against a previous saved snapshot.
