Convert text case while preserving the underlying words

Case conversion changes capitalization patterns such as upper case, lower case, title case or sentence-style capitalization.

Automatic capitalization does not understand every proper noun, acronym or language rule.

Useful case-conversion workflows

  • Normalize headings or labels.
  • Correct accidentally capitalized text.
  • Prepare text for consistent presentation.

What to verify

  • Review names and acronyms.
  • Check language-specific capitalization.
  • Do not assume title case matches every editorial style guide.

Before relying on the result

Keep the source until you have checked the generated output. The source and destination formats can represent structure, layout and metadata differently, so important documents should be reviewed in the application or device where the result will actually be used.
