Intl capability check
Use the current browser Intl API to display localized numbers, currencies, dates, relative time, lists, and locale fallback.
How to inspect Intl capabilities
The Intl capability check processes input only in the current browser; it does not upload anything, connect to the internet, or write to persistent storage.
Prepare an example
Load zh-CN, en-US, ja-JP, CNY, amount 123456.78, and a fixed date by default.
Inspect formatters
View the canonical locale, supported features, and number, currency, date, relative time, and list results.
Compare browsers
Review differences across browsers or locale environments without uploading the input.
Limitations and Notes
- Intl output varies with the browser’s ICU data, language packs, and local time zone.
- The tool only checks the current environment; it does not install language packs or access online translation services.
- The formatted result does not mean that the financial, legal, or localized copy is complete.
FAQ
Why do different browsers produce different results?
Intl data and default locale support may differ; this is an expected difference.
Will this change the system language?
No, it only reads the capabilities of the current browser.
Are amounts calculated according to the tax rate?
No, it only formats the display and does not provide financial calculations.
