Proxy account format converter
Identify and convert account JSON locally in your browser. Import multiple files or JSONL, deduplicate and review individual accounts, and export CPA, Sub2API, Codex and other formats.
Converts in page memory without uploading or saving input, signing in or refreshing tokens. API key sign-in can only be exported in the original Codex format.
Copies and downloads contain full credentials. The preview masks tokens by default. Back up your configuration and check the provider, account and expiry before importing.
1. Import account JSON
2. Review and export
Identify again after changing inputs. No network requests or account verification have been performed.
Supported formats and import notes
OpenAI OAuth supports all seven output formats. Claude, Gemini and Antigravity map only OAuth credential fields for CPA / Sub2API. API key accounts retain the Codex sign-in format only. Converts supplied account information without obtaining new tokens or inferring plans or available credit.
Sub2API and 9router produce batch JSON. CPA, Cockpit, Codex, AxonHub and Codex-Manager export separate account files, which can be packed into a ZIP. Target versions and import requirements may change; check one account first. Successful conversion does not verify sign-in, permissions or model calls.
Import single-account authentication files individually. Codex Auth JSON is not an account list; do not overwrite auth.json with the overview array. Unknown or expired timestamps retain their status. Export time is not account refresh time.
Device, proxy and existing client settings are not migrated. Clear all removes inputs and results from page memory. Manage any copied or downloaded files yourself.
