File Requirements

File Type	Format	Max Size
Character Export	JSON (.json)	8MB
Chat Export	HTML renamed to .txt (.txt)	8MB

File Security

• Upload Location: Files are securely uploaded to ourstorage
• Automatic Deletion: Uploaded files are automatically deleted after the import completes

Managing Your Imports

Checking Import Status

1. Navigate to the List of C.ai Imports page in your account
2. You will see a list of all your import requests
3. Each import shows its status:

• Import succeeded: Import completed successfully
• Import failed: Import encountered an error (check the excerpt for details)

Import Summary Details

For chat imports, the status page will show:

• Total number of chats in the export file
• Number of chats successfully imported
• Number of chats skipped (duplicates)
• Any errors that occurred during import

Duplicate Detection

Our system automatically detects duplicate chats:

• If you import the same chat history twice into the same character, already-imported chats will be skipped
• The system uses the original Character.AI chat_id to identify duplicates
• You can safely re-import chats into the same character without creating duplicate conversations

What Gets Preserved

Content	Preserved
Message Content	Yes – every message is imported exactly as it was
Markdown Formatting	Yes – bold, italic, and bold-italic formatting are maintained
Conversation Flow	Yes – full back-and-forth is maintained in order
Newlines	Yes – line breaks are preserved

Important Notes

• File Format for Chats: For security reasons, you must rename .html files to .txt before upload
• Processing Time: Large imports (1000+ chats) may take several minutes to complete
• File Size Limit: Files larger than 8MB are not supported at this time
• Third-Party Tools: CharacterSphere.ai does not provide Character.AI export tools. Use third-party tools at your own discretion
• Imported Characters: Characters imported from c.ai appear in your private character collection by default
• Imported Chats: Imported chats appear in your chat history and can be continued like any normal conversation

Troubleshooting

Import Failed

• “Invalid c.ai export file”: Make sure you exported from Character.AI using a supported tool. The file must contain the expected JSON structure.
• “File too large”: Your file exceeds the 8MB limit. Try exporting smaller batches of chats.
• “Could not find historyData”: The HTML file may be corrupted or not from Character.AI. Try re-exporting.

Upload Issues

• “File type not allowed”: Make sure character exports are .json and chat exports are renamed to .txt
• Upload stuck: Check your internet connection and try uploading again

Chat Import Issues

• “0 of xx chats imported”: Check if the chats were already imported (duplicate detection). Check the import details for errors.
• Import taking too long: Large imports may take several minutes. Check the List of C.ai Imports page for progress.
