Quick answer: For FANS, request Instagram's official data export in JSON format with followers and following included. If Instagram lets you choose a smaller information scope, choose the follower/following or connections data instead of downloading a full archive full of media you do not need.
FANS is built for one job: compare the accounts you follow against the accounts that follow you back. That means the useful Instagram export data is the followers and following data, not your photos, videos, direct messages, drafts, saved posts, ads information, or a live Instagram login.
If you are trying to avoid a giant download, this is the safest approach: request the official Instagram export, choose JSON, include followers and following, keep the original ZIP intact, save it to Files, and import that ZIP into FANS. You can also read the broader guide on whether FANS needs a full Instagram data export.
What FANS actually needs
FANS needs the official Instagram export data that lets it compare two lists:
- Followers: accounts that follow you.
- Following: accounts you follow.
A non-follower is an account that appears in Following but does not appear in Followers in the same export snapshot. That is the same relationship explained in Instagram followers vs following vs non-followers.
| Export choice | Use it for FANS? | Why it matters |
|---|---|---|
| JSON export with followers and following | Yes | This is the right structured data for a FANS non-follower check. |
| Full JSON archive | Usually yes | It can work if it includes followers and following, but it may be much larger than needed. |
| HTML export | No | HTML is better for manual viewing. FANS expects the structured JSON export workflow. |
| Screenshots, copied lists, spreadsheets, or edited files | No | These are easy to corrupt or mismatch. Use the original official ZIP instead. |
How to request the right export
Instagram's exact menu labels can change, but the safe pattern is stable: use Instagram's official Download Your Information flow and choose an export that contains followers and following.
- Open Instagram or Accounts Center and start a Download Your Information request for your own account.
- Choose JSON as the format. If you need more detail on that choice, see Instagram data export: JSON vs HTML for FANS.
- If Instagram offers information categories, include followers and following or connections data. Avoid selecting unrelated media if you want a smaller download.
- Wait for Instagram to prepare the archive, then download the completed ZIP.
- Save the original ZIP somewhere the iPhone Files picker can access, such as On My iPhone, iCloud Drive, or Downloads.
- Open FANS and import the original ZIP. Do not unzip, translate, rebuild, convert, or merge it first.
Important: If Instagram does not offer a narrow category selector in your current account flow, a full JSON archive is acceptable as long as it includes followers and following. It may just take longer to prepare, download, and save.
Why a focused export is better than a huge archive
A full Instagram archive can include a lot of unrelated material. That may create a bigger ZIP, use more iPhone storage, and make it harder to confirm you picked the right file. A focused followers-and-following export keeps the workflow cleaner.
This matters most when your phone has limited free space, your connection is unreliable, or you are using Files from a cloud provider. If storage is the issue, start with how much iPhone storage an Instagram export needs. If the file is saved but hard to locate, use the guide on where Instagram export downloads go on iPhone.
Do not split out individual JSON files
Even when you know FANS needs follower and following data, do not pull out only a single file such as followers_1.json or following.json. The safest import is the complete original ZIP that Instagram prepared. Splitting files apart can remove context, introduce the wrong account, or leave you with only half of the comparison.
If you want to understand what is inside the ZIP, read where followers and following are in an Instagram data export, but still import the intact archive into FANS.
Why FANS is the best solution after the export
Once the ZIP is ready, FANS is the best way to turn that official export into a practical non-follower list on iPhone. It avoids the risky pattern used by many tracker apps: Instagram passwords, verification codes, cookies, browser sessions, linked-account permissions, API access, server uploads, scraping, automation, and live account control.
FANS compares the follower and following data on your device, works for public and private accounts, and stays read-only. When you want updated results later, request a new Instagram export and import the new ZIP. The guide on refreshing your Instagram unfollower list in FANS explains that repeat workflow.
Safe export checklist
- Use Instagram's official export, not a third-party login flow.
- Choose JSON, not HTML.
- Include followers and following.
- Prefer a focused export when Instagram offers one.
- Keep the original ZIP intact.
- Import through FANS from the iPhone Files picker.
- Download FANS for free; Pro is required to reveal the full non-follower list.
Common mistakes to avoid
Choosing HTML because it looks easier to read
HTML can be useful for manual browsing, but FANS is designed around the official JSON export workflow. If you selected HTML by mistake, request a new export in JSON.
Downloading every photo and video when you only need a list check
Media-heavy exports can be slow and large. For FANS, the follower and following data is the point.
Importing an old export for a current decision
An export is a snapshot from the time Instagram prepared it. If you recently followed, unfollowed, accepted followers, removed followers, blocked someone, changed account type, or changed privacy settings, request a fresh export before making decisions.
Editing the ZIP to make it smaller
Do not edit the archive after Instagram creates it. A smaller but modified file is less trustworthy than the original ZIP.
Quick questions
Can I use a full archive if I already downloaded one?
Yes, if it is a complete official JSON ZIP and includes followers and following. A focused export is usually cleaner for the next refresh.
Can FANS read only my following list?
No. FANS needs both sides of the relationship. A following-only file cannot show who does not follow you back.
Does a smaller export make FANS less accurate?
No, not if it includes the official followers and following data for the right account and snapshot.
Does FANS upload the ZIP to a server?
No. FANS processes the comparison on-device and does not store or sell your Instagram data.
Check Instagram non-followers safely
Request the right official JSON export, keep the ZIP intact, and use FANS to see who does not follow you back without sharing your Instagram login.
