ChatGPT Session Converter

First login to ChatGPT in your browser, then navigate to https://chatgpt.com/api/auth/session, copy the entire JSON displayed and paste it into this tool.

We support pasting ChatGPT Web session JSON, or dropping JSON files such as 9Router Codex OAuth JSON, Codex native auth.json, AxonHub Codex auth.json, or Codex-Manager batch import JSON.

This tool is mainly for Plus accounts. Free accounts, even when converted, do not have the permissions to call the GPT model interfaces via these APIs.

It indicates that parts of the input data could not be recognized as a valid ChatGPT Session. The tool automatically filters out malformed or empty records and lists the specific reason (like a missing accessToken or email) in the issues section below.

Yes, absolutely. You can select or drag and drop multiple JSON files simultaneously. The tool will parse and merge all valid sessions, display them in a unified table, and let you download them as a single combined file.

Sessions retrieved from the official web API only contain an accessToken and lack a refresh_token. For downstream formats that strictly require a refresh_token (such as AxonHub), the tool generates a secure placeholder value to enable successful importing.
