Instagram Export Upload Errors and Fixes

Most upload problems in UnfollowerSpy come from the export file, not from the browser. Instagram can generate several kinds of archives: media archives, message archives, account information archives, and follower/following archives. Only one of those contains the structured JSON lists UnfollowerSpy needs.

This guide explains what each common error means, how to fix it, and how to request the smallest export that works.

Error: This zip file does not contain JSON data

This means the ZIP opened successfully, but there were no `.json` files inside. A common cause is downloading a media-heavy archive that contains photos, videos, stories, or message attachments instead of structured account data.

Fix: request a new Instagram export and choose JSON format. If Instagram lets you customize the export, select only Followers and Following. Do not choose HTML format for this tool.

Error: Followers and following data was not found

This means the ZIP has JSON files, but not the specific follower lists needed for comparison. The expected files usually live in a path like `connections/followers_and_following/followers_1.json` and `connections/followers_and_following/following.json`.

Fix: create a new export with the Followers and Following category selected. If you exported a full archive, make sure Instagram included the `connections` folder.

Why very large ZIP files can fail

Some full Instagram archives are several gigabytes because they include media and message attachments. UnfollowerSpy processes files in your browser, so huge archives can be slow to read and may use more memory than your device can comfortably handle.

The best fix is not to force the huge ZIP through the tool. Request a smaller export containing only Followers and Following. That export is usually much faster and avoids handling private data that is unrelated to the audit.

What to do if Instagram sends multiple files

Instagram may split a large export into several ZIP files. One file might contain media, another might contain account data, and another might contain messages or other activity. If UnfollowerSpy rejects one file, try the ZIP that contains `connections` or `followers_and_following` data.

If you are not sure which file is correct, look at the file size and folder names. A huge archive full of photos and videos is usually not the right one. The useful follower export is often much smaller because it mostly contains structured JSON text.

Quick diagnosis checklist

• If the ZIP contains no JSON files, it is the wrong export format or wrong archive category.
• If the ZIP contains JSON but no follower files, the Followers and Following category was not included.
• If the ZIP is several gigabytes, export only the required category instead of a full account archive.
• If the result seems old, request a fresh export and run the audit on the same day.

How this page was tested

This troubleshooting page was written after comparing two real Instagram ZIP exports: one archive that contained no JSON files and another archive that included `followers_1.json` and `following.json`. That difference is exactly why one file failed and the other could be processed.

The site now checks for the no-JSON case and shows a more specific message. That should help users fix the export instead of assuming the tool is broken.
