How to convert TEXT to CASE
Text case conversion changes how the letters in your text are capitalized. Different contexts demand different cases: UPPER CASE for headings and abbreviations, lower case for URLs and technical fields, Title Case for book titles and article headings, Sentence case for body text, camelCase for JavaScript variables, and snake_case for Python identifiers. Converting by hand across hundreds of words is tedious; this tool does it instantly.
The conversion runs in your browser using JavaScript string methods. Paste any text and select the target case to see the result right away. Your text is not sent to any server.
Paste your text
Enter any text in the input field. Any amount of text works, from a single word to multiple paragraphs.
Select the target case
Choose from options like UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, or others provided by the tool.
Copy the result
The converted text appears in the output field. Highlight it and copy it for use in your document, code, or form.
Apply multiple cases if needed
Convert the same text to different cases for use in different places (e.g., a variable name in camelCase and a display label in Title Case).
Frequently asked questions
What is the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of each major word (The Quick Brown Fox). Sentence case capitalizes only the first word of the sentence (The quick brown fox).
What is camelCase?
camelCase runs words together with each word (except the first) starting with a capital letter: myVariableName. It is standard for JavaScript variable and function names.
What is snake_case?
snake_case joins words with underscores, all lowercase: my_variable_name. It is standard for Python variable names and many database column names.
Is my text uploaded to a server?
No. All conversion runs locally in your browser using JavaScript string methods.
Does Title Case handling handle articles and prepositions correctly?
It depends on the implementation. Basic Title Case capitalizes every word. Sophisticated implementations skip short words like 'and', 'the', 'of', 'in', 'a', 'an' unless they are the first or last word.
