Features and how to use them

Choose a casing rule

The Letter case menu applies one rule to the whole passage.

How this transformation works

UPPERCASE and lowercase convert letter casing directly. Title Case first lowercases the text, then capitalizes letters after whitespace. Sentence case also lowercases first, then capitalizes the beginning and letters following sentence-ending punctuation. These rules do not consult a dictionary of names, acronyms or editorial title styles.

Set the available controls

Choose the options before applying the transformation.

Options and initial settings

Letter case: lowercase, UPPERCASE, Title Case, Sentence case. Initial choice: UPPERCASE.

Opening and applying the tool

The entry screen accepts one UTF-8 TXT, CSV, JSON, XML, HTML or HTM file and opens the editor. Imports are text content, not a PDF or Word conversion. Review the source and choose Convert Text Case when ready. Editing or importing alone does not apply the transformation.

Review, save or continue

The result is editable before you copy or download it.

Using the finished text
