How to Compare Two Instagram Follower Lists Manually

You can compare two Instagram follower exports by hand, line by line in a spreadsheet. It works. It also takes an afternoon and is easy to get wrong. Here is the manual method, and the faster one.

Yes, you can compare two Instagram follower lists by hand. Export your data twice a few weeks apart, open both files, and check which names are missing from the newer one. It works on paper. Past a few hundred followers, matching two long lists by eye turns into an afternoon of squinting and easy-to-miss mistakes.

What You Need Before You Can Compare Anything

Comparing lists only works if you actually have two lists to compare, taken at different points in time. Request your Instagram data export, wait for Instagram to prepare it, and save the ZIP somewhere you will find again. A single export only tells you who follows you right now, not who left, a distinction covered in more detail in can you see who unfollowed you on Instagram. You need a second export, taken a few weeks or months later, before there is anything to compare at all.

The Manual Method, Step by Step

  1. 1.Unzip both exports and open connections/followers_and_following/followers_1.json from each one in a text editor or spreadsheet tool.
  2. 2.Pull just the usernames out of each file. Every entry stores the username inside string_list_data[0].value, buried under a layer of JSON structure you have to skip past by hand.
  3. 3.Paste the older list's usernames into one spreadsheet column and the newer list's into another.
  4. 4.Sort both columns alphabetically, then scroll down both at the same time, line by line, looking for a name in the old column with no match in the new one.
  5. 5.Every name you find that way, present in the old export and missing from the new one, unfollowed you sometime in between.

Why This Breaks Down at Any Real Size

This works, technically, on an account with 40 followers. It falls apart fast past a few hundred. Instagram's export format is not a clean list of names, it is nested JSON built for machines to parse, not people to read, so step two alone can take longer than the actual comparison. Sort a spreadsheet wrong, and a genuine unfollow hides behind a formatting mismatch (an extra space, a capitalization difference, an emoji Instagram renders slightly differently between exports) that makes two identical usernames look like they do not match. On an account with a few thousand followers, matching two columns by eye is close to a full afternoon spent staring at a spreadsheet, with no guarantee you caught every name.

In Short

  • Comparing two Instagram exports by hand works in theory: line up the usernames and look for what is missing.
  • The Instagram export format buries each username inside nested JSON, so pulling clean names out is the slowest part of the manual method.
  • Formatting mismatches (spacing, capitalization, emoji rendering) can hide a real unfollow inside a spreadsheet that looks like it matches.
  • A tool built to parse the export format directly skips the manual extraction step and compares both lists in seconds, not hours.

The Faster Way to Compare Two Lists

WhoUnfollowed does the exact same comparison described above, reading the export's JSON structure directly instead of asking you to untangle it by hand. Upload your first export, then your second when you have it, and it lines up both lists in your browser and shows you exactly who is missing, by name, in under a second. Nothing is uploaded to a server, the file never leaves your device. If you have not pulled your first export yet, the full walkthrough is in how to see who unfollowed you on Instagram. If you are wondering whether a tool like this is trustworthy before you upload anything, how an unfollow checker actually works breaks down exactly what it does with your data and why it does not need your password to do it.

Frequently asked questions

Can I compare two Instagram follower lists without an app?

Yes, by manually cross-checking the usernames in two dated data exports, though it is slow and error-prone past a few hundred followers.

What file do I need to compare Instagram followers?

The followers_1.json file (or followers_2.json, followers_3.json if you have over 5,000 followers) inside the connections/followers_and_following folder of your Instagram data export.

Why don't two exports match up even when nothing seems to have changed?

Small formatting differences, like extra spaces, capitalization, or how an emoji in a username gets rendered, can make an identical username look like a mismatch during a manual comparison.

Is there a faster way to compare two Instagram follower lists?

Yes, a tool that reads the export files directly, such as WhoUnfollowed, compares two dated exports and lists every unfollow by name in under a second, without any manual spreadsheet work.

Do I need my Instagram password to compare my follower lists?

No, comparing two of your own data exports only requires files Instagram already gave you; no password or login is needed for either the manual or automated method.

Skip the spreadsheet.

Matching two follower lists by eye is slow and easy to get wrong. Upload both of your Instagram exports to WhoUnfollowed and see exactly who unfollowed you, by name, in your browser, in under a second. No password, nothing uploaded.
