When to use lowercase
Lowercase is handy for cleaning data before you compare or deduplicate it, for hashtags and usernames, and for undoing text typed with caps lock on. To get normal capitalization back afterwards, run the result through the Sentence case converter.
Accented and non-English letters
Letters outside the basic English alphabet, such as É, Ö, Ñ, and Greek or Cyrillic capitals, are converted too.
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.
Lowercase in data cleanup
Computers treat “Apple”, “APPLE”, and “apple” as three different values. Before you compare two lists, remove duplicates, or import email addresses into a mailing tool, converting everything to lowercase makes matching reliable. Email addresses are a good example: the part after the @ is never case-sensitive, and in practice almost no mail provider treats the part before it as case-sensitive either.
Lowercase is also the safe choice for usernames, hashtags in analytics reports, file names on web servers (which are often case-sensitive), and tags in a content system.
Lowercase as a style
Some brands and writers use all-lowercase deliberately for a casual or minimalist feel, in logos, social bios, and taglines. It works for a few words. For anything longer, readers rely on capitals to see where sentences and names begin.
