Choose a title-case rule set and keep first/last words capitalized without changing unrelated text.
Case conversion is mechanical. Locale-aware upper/lower mappings are used where the browser supports them; natural-language title capitalization and proper-noun restoration can require editorial judgment.
The optional minor-word list is a practical heuristic, not a claim of full APA, Chicago, MLA, or AP style-guide compliance.
Paste once and move between prose and identifier formats without sending text away.
Editorial title-case rules have edge cases, syllable counts are heuristic, Unicode style substitutions depend on font/app support, and normalized or visually similar Unicode text is not automatically safe or equivalent. Structural XML comparison should use the XML-aware engine rather than a raw line diff.
Use the tool first, then apply these checks to verify inputs, interpret the result, and hand it off without displacing the primary workflow.
Title case is not one universal algorithm. Editorial styles differ on short prepositions, conjunctions, infinitive “to,” hyphenated compounds, words after colons, and capitalization within proper names. Select the convention required by the publication, school, product, or organization first. An automatic converter can apply a consistent rule set, but the final title still needs a quick review for names, acronyms, trademarks, and domain-specific wording.
Brand names, programming identifiers, chemical notation, mixed-case product names, and acronyms can be damaged by generic case conversion. Keep a copy of the original text and scan the converted output for tokens such as iPhone, eBay, JavaScript, LaTeX, DNA, or organization-specific spellings. If the same exception appears repeatedly, use an editing workflow that supports a custom exception list rather than manually repairing every title after conversion.
Colons, dashes, slashes, quotes, parentheses, and hyphens can affect which word begins a new title segment, but punctuation alone cannot reveal the writer’s intended grammar. A hyphenated compound may capitalize both parts under one style and only one part under another. Review titles with nested punctuation or unusual compounds, especially when they will appear in navigation, metadata, citations, or published headings where consistency is visible.
Some destinations impose their own casing or length expectations. Search snippets, academic references, app-store listings, article headings, and code labels may not use the same convention. After conversion, paste the result into the actual destination and verify that capitalization, Unicode characters, spacing, and punctuation survived unchanged. Case conversion changes presentation; it should not rewrite wording or silently normalize meaningful symbols unless that behavior was explicitly requested.
