Many programs in Microsoft Office 2010 and 2013, including Word, Outlook and Excel, have features that automatically convert the case of a selection of text. With a program's change case option, you can shift text containing either all caps or mixed cases into lower case without retyping it. Free Office alternatives, including OpenOffice, offer a similar feature, as do several free Web-based tools.
Change Case in Word
Microsoft Word can change the case of text between five styles: "Sentence Case," "Lowercase," "Uppercase," "Capitalize Each Word," and "Toggle Case." To switch a capitalized line of text to lower case, select it, click "Change Case" -- the "Aa" icon -- on the "Home" tab and pick "Lowercase." Alternatively, press "Shift-F3" to switch the selected text between three options: all caps, all lower case and sentence case.
Change Case in Other Programs
Some other programs have a change case feature similar to Word's, while others work vastly differently. Outlook, for example, has the same "Aa" icon as Word, but keeps it in the "Format Text" tab. In Excel, on the other hand, you have to use the "LOWER" function to change capital letters in a cell to lower case. Excel also has the "UPPER" function to capitalize letters and the "PROPER" function, which works similarly to "Capitalize Each Word" in Microsoft Word, except it also capitalizes letters that appear after numbers and symbols. Most alternative word processors also include a way to change text case: Both OpenOffice Writer 4 and LibreOffice 4 have a "Change Case" option in the "Format" menu.
Change Case Online
When writing in a program without a change case feature, such as Notepad or Wordpad, you can copy and paste text -- press "Ctrl-C" and "Ctrl-V" -- into Word to change the text case. If you don't have Word or another word processor, you can still get the job done through one of several websites. Convert Case, Text-Case Converter and TitleCase all offer conversion to lower-case text, as well as other case conversions not offered by Word, such as "Alternating Case" on Convert Case or "CamelCase" on TitleCase (links in Resources). After a site converts the text, copy the result and paste it back into your document. Convert Case can also save converted text as a TXT file.
Change All-Caps Fonts
Some fonts, such as Algerian, include only capital letters. Using "Change Case" nor retyping text can force these fonts to display lower case letters. But even though you can't see lower-case letters in an all-caps font, the computer invisibly tracks the capitalization of each letter you type, so you can change to another font to reveal the text's proper capitalization. Other fonts, such as Copperplate Gothic, use small caps. These fonts don't include lower-case letters, but instead use two sizes of text to distinguish caps from lower case. As with all-caps fonts, switch to a different typeface to view your text in lower case.
