How to clean ChatGPT exports for AI prompts

Short answer

Clean a chat export by removing speaker labels, divider lines, timestamps, and repeated blank lines while keeping the actual conversation text in order. Do not summarize or rewrite the chat unless that is a separate step.

What to remove first

Keep turns in orderPreserve the sequence of the conversation so later prompts still have the context they need.
Remove repeated labelsStrip line-start labels such as User, Assistant, System, Developer, Human, AI, and ChatGPT said when they are only export scaffolding.
Remove separatorsDelete divider lines, extra blank lines, and copied UI artifacts that do not change meaning.
Check token sizeAfter cleanup, count or estimate tokens before pasting long chats into another AI tool.

Questions

Should I remove every speaker label?

Remove labels only when they are repeated export scaffolding. Keep names or roles when the distinction changes the meaning of the conversation.

Does cleaning a ChatGPT export make it safe to share?

No. Formatting cleanup is not redaction. Review private content separately before sharing.

Does the cleaner call an AI model?

No. It applies deterministic local cleanup rules in your browser.
