What is Text Case Converter?
Text Case Converter transforms text between the naming conventions used in programming and writing. Developers constantly switch between snake_case for Python and SQL, camelCase for JavaScript and Java, PascalCase for C# classes and React components, kebab-case for CSS and URLs, and other formats.
The tool detects word boundaries intelligently — handling transitions between uppercase and lowercase letters, digits, underscores, hyphens, and spaces — so it correctly converts identifiers regardless of their current format. All variants are shown simultaneously, making it easy to compare and pick the one you need.
How to Use Text Case Converter
Type or paste any text: a variable name, function name, file name, or any phrase. The tool shows all case variants at once in a clean list with copy buttons next to each. Tap any variant to copy it to your clipboard.
The word boundary detection handles common edge cases: acronyms like “HTTP” and “API” are treated as single words, digit sequences are preserved, and Unicode characters are normalized correctly. The tool also supports the share sheet, so you can select text in any app and convert it without switching to DevKit first.
Common Use Cases
- Cross-language development: Convert variable names between Python’s
snake_caseand JavaScript’scamelCasewhen working on full-stack projects. - API integration: Transform JSON field names between the naming conventions used by different APIs (snake_case vs camelCase).
- CSS class naming: Convert component names to kebab-case for CSS classes and BEM naming conventions.
- Database column naming: Convert between application-layer camelCase identifiers and database snake_case column names.
- URL slug generation: Convert titles and names to kebab-case slugs for URLs and file paths.
