Frequently Asked Questions
What case conversions are supported?
Twelve case types: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, kebab-case, PascalCase, CONSTANT_CASE, dot.case, tOGGLE cASE, and aLtErNaTiNg CaSe.
Does it support bulk conversion?
Yes. For code-style cases (camelCase, snake_case, kebab-case, PascalCase, CONSTANT_CASE, dot.case), each line is converted independently, making batch processing easy.
What are the use cases?
Converting variable names between coding conventions (camelCase to snake_case), formatting titles for SEO, normalizing text for databases, preparing content for social media, and cleaning up messy text formatting.
Can I chain multiple conversions?
Yes. Use the "Use as Input" button to feed the output back as input. This lets you chain conversions — for example, first convert to lowercase, then to Title Case.
Does it preserve line breaks?
Yes. All case conversions preserve your original line breaks and paragraph structure. Code-style cases process each line as a separate entry.
Does it run in my browser?
Yes. Once the page loads, the tool works entirely without an internet connection. All processing happens in your browser — no data is sent to any server.
