About the Uppercase Text Converter
Uppercasing looks trivial until non-English text arrives. This tool applies the full Unicode uppercase mapping rather than a simple A to Z substitution, so é becomes É, ç becomes Ç, and Greek or Cyrillic letters take their own capital forms. Digits, punctuation, emoji and spacing pass through untouched, and line breaks are preserved, so a list stays a list.
One case is worth knowing about: the German sharp s. ß has no single capital in the standard mapping, so Straße comes out as STRASSE and the string grows by a character. Anything downstream that compares lengths, or lowercases the result expecting to get back where it started, will not round-trip. Typographic ligatures behave the same way, with fi expanding to two letters.
A typical job is preparing values for a system that stores identifiers in capitals only: airline booking references, warehouse bin codes, older mainframe address fields that reject mixed case on import. Paste the whole column, convert once, paste it back. For the return trip use Lowercase Text, and when you need camelCase, snake_case or a heading instead, the Case Converter covers fourteen styles in one place.
How to use

Common questions
- Does it uppercase accented letters?
- Yes. é becomes É and other accented letters convert per Unicode rules.
- What about the German ß?
- Uppercasing ß yields SS in modern Unicode, which this tool follows.
- Are numbers changed?
- No. Only letters are affected.
