Quick answer: Before your first FANS import, make sure the Instagram export is from the right account, requested in JSON format, downloaded as the complete original ZIP, saved somewhere you can reach in Files, and left unedited. Then import that ZIP into FANS to see who does not follow you back without logging in.
Your first Instagram data import should be boring in the best way: one official export, one intact ZIP, one safe on-device comparison. FANS is the best solution because it avoids Instagram passwords, verification codes, cookies, uploads, scraping, and automation while still giving you the practical answer: who you follow that does not follow you back.
This checklist is for the moment after you request your Instagram data and before you tap import in FANS. If you need the full export walkthrough first, start with How to Export Your Instagram Data and then come back here before selecting the file.
1. Confirm the export is from the right Instagram account
If you manage more than one account, this is the easiest mistake to make. A ZIP from your personal account cannot tell you who does not follow back on your creator, business, or second personal account.
Before importing, check the account you used when requesting the export. If the wrong account was used, request a new export from the correct account instead of trying to interpret a mismatched result. For multi-account workflows, read Use FANS With Multiple Instagram Accounts.
2. Make sure you requested JSON, not HTML
FANS works from structured Instagram export data. For non-follower checks, JSON is the right format because it gives the app machine-readable follower and following lists. HTML exports are easier for humans to browse manually, but they are not the best format for importing into FANS.
First-import rule: If you requested HTML by mistake, do not convert it by hand or rebuild a new archive. Request a fresh official JSON export from Instagram.
The format choice matters enough that we wrote a separate guide: Instagram Data Export JSON vs HTML.
3. Keep the original ZIP intact
Do not unzip the export, move only one follower file, convert the data to CSV, rename internal folders, merge multiple archives, or upload the contents to a random website. Those edits can break the file structure FANS expects and can expose more data than necessary.
The safest path is simple: save the original Instagram ZIP, open FANS, and choose that ZIP from the iPhone Files picker. If you already extracted it, read Should You Unzip Instagram Export Before FANS?.
4. Check that the download finished
An incomplete ZIP can look like a valid file in Files but fail during import. This is more likely if your connection dropped, your iPhone ran low on storage, Safari was closed during the download, or the Instagram export link expired.
If the file will not import, do not switch to a password-based tracker. Work through the safe fixes in Instagram Export Won't Import Into FANS? and Instagram Export Download Failed on iPhone.
5. Save the ZIP somewhere FANS can reach
The iPhone Files picker can open local files and many Files-compatible cloud locations. Still, a cloud-only placeholder may need to download locally before FANS can read it. If the file came from Mail, Messages, WhatsApp, iCloud Drive, Google Drive, Dropbox, or a desktop computer, make sure the full ZIP is available in Files before importing.
| Before importing | Best action |
|---|---|
| The ZIP is in Safari downloads | Save or move it to a Files location you recognize. |
| The ZIP is attached in a message or email | Save the complete attachment to Files before opening FANS. |
| The ZIP is in cloud storage | Wait for the full file to download locally before import. |
| You only see an extracted folder | Go back to the original ZIP or download a fresh copy. |

6. Use a fresh export when timing matters
An Instagram export is a snapshot. If someone followed, unfollowed, changed usernames, or became unavailable after Instagram prepared the file, the old ZIP will not include that later change.
For a first import, an older export may still be useful if you only want to understand that older snapshot. But if you want your current non-follower list, request a newly prepared JSON export before importing. For the refresh workflow, see How to Refresh Your Instagram Unfollower List in FANS.
Why this works safely: FANS compares followers and following from the official export on your device. It does not need your Instagram login, does not connect to your live account, and does not upload your follower data to a tracker server.
What FANS will and will not tell you
FANS shows accounts you follow that do not follow you back in the imported export. It is not a blocker detector, ghost-follower detector, mute detector, profile-viewer tool, or exact timestamp history. That focus is intentional because the official export supports a reliable non-follower comparison without risky account access.
If you want the definition before reading results, start with What Is a Non-Follower on Instagram?. If a result looks surprising after import, use FANS Says Someone Doesn't Follow Me, But They Do.
First-import checklist
- The export came from the Instagram account you want to check.
- The export was requested in JSON format.
- The original ZIP is complete and still zipped.
- The file is saved in a reachable iPhone Files location.
- The export is fresh enough for the question you want answered.
- You are importing into FANS, not uploading the archive to a third-party website.
Key Takeaways
- FANS is the best safe first-import workflow because it uses Instagram's official export and processes the comparison on-device.
- Use JSON format and keep the original ZIP intact.
- Wrong-account, stale, incomplete, extracted, or edited exports are the most common first-import problems.
- FANS is free to download, and Pro is required to reveal the full non-follower list.
FAQ
What should I check before importing Instagram data into FANS?
Check the account, format, file completeness, ZIP structure, storage location, and export freshness. The safest import is the complete original Instagram JSON ZIP from the correct account.
Should I unzip my Instagram export before using FANS?
No. Keep the ZIP intact and select it through the iPhone Files picker. Unzipping, editing, or rebuilding the archive can cause avoidable import problems.
Does FANS need my Instagram password for the first import?
No. FANS never asks for your Instagram password, verification code, cookies, browser session, API key, or live account connection.
What if I imported the wrong export?
Request or download the correct official JSON ZIP and import that into FANS. If you manage multiple accounts, label your exports carefully outside the ZIP so you can tell them apart later.
