Frequently Asked Questions

How do I convert text to uppercase?

Paste it above — the result appears instantly. In a spreadsheet, use =UPPER(A1); in most editors, select the text and press the case-change shortcut.

Does it handle accented characters?

Yes. é becomes É, ñ becomes Ñ, and Greek and Cyrillic uppercase correctly too. Turkish dotted and dotless i are a known edge case that depends on locale rules.

Should I use all caps in my writing?

Sparingly. Blocks of capitals are measurably slower to read because the word shape disappears, and in email they read as shouting. They work for short labels and acronyms.
