Translate JSON i18n files instantly without breaking placeholders or structure - LocalizeJSO

I kept running into the same issue when translating JSON i18n files with AI.

It works… until it doesn’t.

keys get changed
placeholders like {name} or %d break
sometimes the JSON isn’t even valid

Which means you still end up manually fixing everything.

So I built a small tool to handle this properly.

You upload a JSON file, choose a language, and it returns:

same keys
placeholders preserved
valid, production-ready JSON

No cleanup needed.

What I’m trying to figure out now:

Is this something you’d actually use in your workflow?
Or is this more of a “nice to have” than a real need?
What would make it something you come back to regularly?
