What does the Case Converter do?
Case conversion rewrites identifiers between styles used in JavaScript, Python, CSS and constants. Useful when renaming a field across languages.
Case Converter
camelCase, snake_case, kebab-case, PascalCase and more. Nothing is uploaded.
The Case Converter splits words at case humps, spaces, hyphens and underscores and renders five conventions at once — camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE — live as you type.
- camelCase
- formatJsonLocally
- PascalCase
- FormatJsonLocally
- snake_case
- format_json_locally
- kebab-case
- format-json-locally
- CONSTANT_CASE
- FORMAT_JSON_LOCALLY
How does the Case Converter work?
The input is split on spaces, dashes, underscores and camel humps, then rejoined in the target convention. All of that is string processing in this tab.
Does this upload my text?
No. This page never sends your input to a server — formatting, decoding and hashing all run in this tab, on this device.How that works.
Frequently asked questions
Will it preserve acronyms?
Simple conversions treat letters uniformly. HTTPResponse may become http_response, which is usually what you want in snake_case.
Does it change meaning?
No. Only separators and capitalization change.
Can I convert a whole file?
Paste a phrase or identifier. This is not a source-code refactor tool.
Is text uploaded?
No.
