A Wrapper That Stops ChatGPT from Breaking Your JSON Translations

What it does

chatgpt-i18n is a web app that feeds your i18n JSON files to ChatGPT without letting the model chew them up. It offers a browser-based editor for viewing and tweaking translations, then exports multiple locale files in one go. The whole thing is essentially a careful wrapper around OpenAI’s API, built by a developer who got tired of babysitting Google Translate tabs.

The interesting bit

The real trick is a chunking strategy that splits oversized JSON files into smaller pieces before sending them to the API, which keeps ChatGPT from mangling the structure. The author notes this is still a work in progress and currently runs slow, occasionally bumping into Vercel FaaS limits.

Key highlights

• Web editor for viewing and editing translated locale files.
• Bulk export of multiple locale files at once.
• Chunks large JSON to reduce the chance of ChatGPT breaking syntax.
• Built to replace Google Translate and raw ChatGPT for localization workflows.

Caveats

• The JSON chunking feature is marked work-in-progress and can be slow; the author reports it sometimes exceeds Vercel FaaS limits.

Verdict

Worth a look if you maintain multilingual apps and have watched ChatGPT hallucinate closing braces. Skip it if you need a mature, fully managed translation pipeline; this is still a personal productivity tool with rough edges.
