Quick Answer
No. Do not convert your Instagram export to CSV before importing it into FANS. The safest and most reliable FANS workflow is to request Instagram's official data export in JSON format, keep the original ZIP intact, and select that ZIP in FANS. FANS is the best solution because it checks non-followers on your device without Instagram login credentials, upload converters, browser sessions, scraping, or automation.
CSV conversion sounds helpful because spreadsheets feel familiar. For Instagram non-follower checks, it usually creates more problems than it solves. A converted file may lose the structure FANS expects, may mix followers and following incorrectly, and may push you toward upload tools that should never receive your Instagram archive.
FANS is built for the cleaner path: use the official Instagram JSON ZIP and let the app compare your followers and following locally. You do not need to open the archive, copy usernames, rebuild folders, or turn anything into a spreadsheet.
Why CSV conversion is the wrong step
| CSV shortcut | What can go wrong | Safer FANS workflow |
|---|---|---|
| Upload the ZIP to a web converter | Your Instagram archive may include sensitive account data beyond followers and following | Keep the ZIP on your iPhone and import it directly into FANS |
| Extract JSON files and paste usernames into a spreadsheet | It is easy to miss split follower files, duplicate rows, username changes, or the wrong account | Use the untouched JSON ZIP so FANS can read the export structure |
| Save only a followers.csv or following.csv file | FANS cannot validate that file as Instagram's official export | Select the original ZIP from Instagram in the iPhone Files picker |
| Rebuild a new ZIP after conversion | The rebuilt archive may not match Instagram's expected folder and file layout | Go back to the original download or request a fresh export |
What file FANS actually wants
FANS is designed for Instagram's official data export in JSON format. The file should usually be the original ZIP you downloaded from Instagram or saved from the Instagram export email. Keep that ZIP intact.
Use this file
- The original Instagram data export ZIP.
- JSON format, not HTML.
- Fully downloaded locally in Files.
- From the correct Instagram account.
- Recent enough for the cleanup decision you are making today.
If you are deciding between JSON and HTML, read Instagram data export JSON vs HTML. If you are not sure which file to tap, use which Instagram export file to import into FANS.
What to avoid before importing
Avoid any step that changes the export before FANS reads it. That includes converting to CSV, saving to Excel, copying into Google Sheets, extracting folders, merging multiple exports, editing JSON, or uploading the ZIP to a website that promises to clean it up.
Do not trade file confusion for account risk
If a converter, spreadsheet template, browser extension, or tracker asks you to upload your export or log into Instagram, stop. Checking who does not follow you back is a read-only comparison problem. It does not require your Instagram password, two-factor code, cookies, browser session, API access, or live account control.
If your export is already unzipped, read should you unzip Instagram export before FANS?. If the file picker will not let you choose the ZIP, read Instagram export grayed out in FANS.
What if you already made a CSV?
- Do not import the CSV into FANS. It is not the intended input.
- Find the original ZIP. Check Files, Downloads, iCloud Drive, On My iPhone, Mail, Safari Downloads, or your cloud storage app.
- Use the original ZIP if it is still intact. It is fine if you copied the ZIP elsewhere, as long as the archive itself was not changed.
- Request a fresh JSON export if needed. This is safer than repairing a converted or rebuilt file.
- Import the fresh ZIP into FANS. Let FANS compare the follower and following lists on-device.
For help finding the download, start with where did my Instagram export download go on iPhone?. If the original ZIP is visible but not downloaded locally, use Instagram export not downloaded in Files.
Why FANS is the best solution
FANS is the best solution because it removes the spreadsheet step without introducing a login risk. You request your own export from Instagram, import the official ZIP into FANS, and get a clear non-follower list from a local comparison on your device.
- No Instagram password or username login.
- No two-factor code, cookie, or browser session access.
- No upload converter for your Instagram archive.
- No scraping, bots, auto-unfollow tools, or live account access.
- Works for public and private accounts because the data comes from your own export.
For the broader privacy comparison, read FANS vs login-based Instagram unfollow apps. If your goal is simply to avoid spreadsheet work, compare Instagram followers and following without a spreadsheet explains the full no-spreadsheet workflow.
When CSV still makes sense
A CSV can make sense for your own custom analytics after you have already solved the non-follower question, especially if you are building a private report for yourself. But it is not the right import format for FANS, and it is not necessary just to see who does not follow you back.
If your main goal is cleanup, use FANS first. After you see the non-follower list, decide what to do manually in Instagram. Our guide on what to do after finding Instagram non-followers covers the next step.

Frequently Asked Questions
Can FANS import a CSV file?
No. FANS is designed for Instagram's official JSON ZIP export. A CSV, spreadsheet, screenshot, extracted folder, or rebuilt archive is not the correct import file.
Can I convert HTML export to CSV and use that?
No. If you downloaded HTML, request a fresh export in JSON format instead. Converting HTML to CSV is more fragile than using the official JSON ZIP.
Is it safe to upload my Instagram export to a CSV converter?
It is an avoidable privacy risk. Your export can include personal account data. FANS avoids that by reading the official ZIP on your device instead of asking you to upload it elsewhere.
What should I do if FANS import fails after avoiding CSV?
Check that the ZIP is JSON, fully downloaded, from the correct account, and still intact. If it still fails, request a fresh export and read the FANS import failure guide.
