What is Sentence case?

Sentence case capitalizes only the first letter of the first word in a sentence (and proper nouns, though automatic converters usually miss proper nouns). Example: 'This is a sentence.'

Title Case capitalizes the first letter of every major word. Small words (conjunctions, articles, and prepositions like 'and', 'the', 'in') are usually left lowercase. Example: 'The Lord of the Rings'.

camelCase removes all spaces and capitalizes the first letter of every word except the first one. It is widely used in programming. Example: 'myVariableName'.

PascalCase is like camelCase, but it capitalizes the very first letter as well. Example: 'MyClassName'.

snake_case replaces all spaces with underscores and makes all letters lowercase. It is common in Python programming and file naming. Example: 'my_file_name'.

kebab-case (also called dash-case) replaces all spaces with hyphens and makes all letters lowercase. It is standard for URLs. Example: 'my-blog-post'.

Can I convert ALL CAPS back to normal text?

Yes, just paste the ALL CAPS text into the converter and select 'Sentence case' or 'lowercase'. You will need to manually capitalize proper nouns afterward.

Why is case formatting important?

In writing, it ensures stylistic consistency. In programming, strict case conventions are required because variables like 'MyVar' and 'myvar' are treated as completely different entities.
