System FAQ

How do I convert text to title case online?

Paste your text and click 'Title Case'. The tool capitalizes the first letter of each major word while keeping articles (a, an, the) and prepositions lowercase, following standard title case rules.

How do I fix text that's accidentally in all caps?

Paste your ALL CAPS text and click 'lowercase' or 'Sentence case'. 'lowercase' converts everything to lowercase. 'Sentence case' keeps the first word of each sentence capitalized.

What is camelCase and when do developers use it?

CamelCase is a naming convention where words are joined without spaces and each word after the first is capitalized (e.g., myVariableName). Developers use it for variable names in JavaScript, Java, and Swift. It comes in two forms: lowerCamelCase (variables) and UpperCamelCase/PascalCase (classes).

What is snake_case and where is it used?

snake_case joins words with underscores in lowercase (e.g., my_variable_name). It's the standard naming convention in Python, Ruby, SQL column names, and file names in Linux systems.

What is the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of most words (Best Free Online Tool). Sentence case only capitalizes the first word of a sentence (Best free online tool). Title Case is used for headlines; sentence case is used in everyday writing.
