Suggestion: Detect and Handle Duplicate Imports (Exact Matches)

[admdanielspalma]

When importing conversations from ChatGPT (OpenAI export JSON), it's common to test or import the same file more than once... especially when migrating or backing up.

However, LibreChat currently imports all data again, resulting in exactly duplicated chats — same title, same messages, same timestamps.

Problem

• There's no check to detect or avoid importing conversations that are already present.
• Re-importing the same JSON creates a cluttered and confusing history.
• Users then need to manually delete duplicates, which is slow and error-prone.

Suggested Solution

• Add an option during import like:
  ✅ Skip exact duplicates (based on title, timestamp, or conversation hash)

• Also, to have a "Find and remove duplicates" tool.

This could:

• Detect chats with identical content and metadata.
• Prompt the user to confirm deletion or merging.
• Help keep the chat list clean, especially for heavy users or team setups.

Benefits

• Prevents chat history clutter.
• Saves time for users managing backups or syncing data across devices.
• Improves the overall experience of migration and long-term usage.

Thanks again for the great work!
