Text Case Conversion for Titles, Slugs, and Cleanup
Learn when to use title case, sentence case, uppercase, lowercase, camelCase, kebab-case, and slug-style text cleanup.
Quick answer
Use text case conversion when the words are right but the format is wrong for a headline, URL slug, variable name, label, or batch-cleanup task. Pick a case style based on where the text will be used, then review acronyms and brand names manually.
Choose case by destination
Title case works for headings, sentence case works for readable labels, uppercase works for short codes, lowercase works for normalized matching, camelCase works for JavaScript-style identifiers, and kebab-case works well for URL slugs.
- Use sentence case for human-readable UI labels
- Use kebab-case for slugs and file names
- Use camelCase or snake_case when a codebase expects it
Review words that tools cannot infer
A case converter can change letter shape, but it cannot know every acronym, product name, or editorial rule. Review terms such as API, JSON, iOS, AppHelp, and brand names before publishing.
Batch cleanup safely
When cleaning a long list, convert a copy first. Then use prefix/suffix or line cleanup tools only after case conversion, so each line keeps one stable record.
Frequently asked questions
Should URL slugs use spaces, underscores, or hyphens?
Hyphenated lowercase slugs are usually the safest choice for URLs because they are readable and widely expected.
Can a case converter preserve acronyms automatically?
Some converters can preserve common acronyms, but you should still review product names and technical terms before publishing.
