Uppercase and readability
All-caps text is slower to read in long passages because words lose their outline shape. Keep it for short items like headings, warnings, product codes, and mailing addresses.
Special characters
The German ß becomes SS, following the standard Unicode rules. Numbers and symbols are left alone.
Changing case in Word, Google Docs, and Excel
Microsoft Word: select the text and press Shift+F3 to cycle through lowercase, UPPERCASE, and Capitalize Each Word, or use the Change Case (Aa) button on the Home tab, which also offers Sentence case. On a Mac, use Format › Change Case.
Google Docs: select the text, then choose Format › Text › Capitalization.
Excel and Google Sheets: use =LOWER(A1), =UPPER(A1), or =PROPER(A1), then paste the results back as values. For anywhere else, such as email, a CMS, or a form, paste your text into this converter.
