Convert text to uppercase
This uppercase converter changes cased letters to their capital forms without removing spaces, punctuation, or line breaks. Hello World Example becomes HELLO WORLD EXAMPLE.
Uppercase text is commonly used for headings, labels, identifiers, comparison keys, and data normalization. It does not automatically create programming constant names because spaces remain unchanged.

Unicode case conversion can expand or transform some characters differently from a simple ASCII a–z replacement. Locale-specific typography may require additional review.
Uppercase FAQ
Does this create CONSTANT_CASE?
No. Use Constant Case when words should also be separated with underscores.
Will numbers and symbols change?
Characters without uppercase forms normally remain unchanged.
Can uppercase output recover the original capitalization?
No. Conversion discards distinctions such as title case and mixed capitalization.
