Text Case Converter
About Text Case Converter
The Text Case Converter instantly transforms text between multiple casing formats — from all-uppercase to all-lowercase, to Title Case for headlines, camelCase for JavaScript variables, snake_case for Python and database identifiers, and more. This is a daily-use tool for developers (who frequently need to convert between naming conventions), writers and editors (who need to quickly reformat all-caps text from copy-paste sources), content creators (correcting formatting on copied text), and anyone working with databases or configuration files that have specific case requirements. The conversion is instant, runs locally in your browser, and handles text of any length.

Frequently Asked Questions
What case formats are supported?
We support: UPPERCASE (all letters capitalized), lowercase (all letters in lower case), Title Case (first letter of each major word capitalized, articles and prepositions in lower case), Sentence case (only the first letter of each sentence capitalized), camelCase (first word lowercase, subsequent words capitalized, no spaces — e.g., myVariableName), PascalCase (every word capitalized, no spaces — e.g., MyClassName), and snake_case (all lowercase with underscores — e.g., my_variable_name).
Can I convert code variable names between conventions?
Yes. This is one of the most popular developer use cases. For example, you can convert a snake_case database column name (user_first_name) to camelCase (userFirstName) for a JavaScript variable, or to PascalCase (UserFirstName) for a C# property name. Simply paste the identifier and click the target case format.
