Uppercase Converter
Convert input text to locale-aware uppercase.
How to use
- Enter the text, run the conversion, and copy the result if needed.
Capabilities and scope
Digits, punctuation, and spacing are preserved while characters with case mappings are transformed through toLocaleUpperCase.
How it works
The runner applies JavaScript String.toLocaleUpperCase() to the complete input.
Example
Hello 123 becomes HELLO 123.
Useful for
- Uppercase headings or identifiers quickly
Before you use it
- Case rules can vary by language and some mappings can change length; the tool does not infer stylistic intent.
Frequently asked questions
