Guide
Text case conversion workflow
Convert API fields, environment variables, filenames, and document titles into camelCase, snake_case, kebab-case, PascalCase, and related formats.
Clean URLs and filenames
Turn titles into slugs or kebab-case values for document paths, image names, and anchor links.
Review before bulk edits
Inspect how acronyms, numbers, and spacing are split before applying the result broadly.

Workflow
How to use it
- Enter the text or identifier list you want to convert.
- Choose the output case and review the converted value.
- Manually check values containing acronyms, numbers, hyphens, or underscores.
- Before pasting into code, compare the result with the existing naming convention.
Examples
Real input and output
One input, every convention
Input
user profile imageOutput
camelCase userProfileImage
PascalCase UserProfileImage
snake_case user_profile_image
kebab-case user-profile-image
CONSTANT USER_PROFILE_IMAGEConverting an existing identifier
Input
getHTTPResponseCodeOutput
snake_case get_http_response_code
kebab-case get-http-response-codeConsecutive uppercase acronyms are where implementations disagree most.
Troubleshooting
Errors you will hit
Acronyms split in odd places
Runs of capitals like HTTP, ID, or URL are hard to segment. Some tools turn getHTTPResponse into get_h_t_t_p_response. Check acronyms by eye after converting.
Digit boundaries
Tools disagree on whether the digits in user2Name form a word boundary. Verify before using the result somewhere irreversible, like a database column name.
Review
Things to check
Acronyms are team-specific
Terms like URL, ID, and API can be written as url, Url, or URL depending on convention. Adjust after conversion.
Meaning can shift
Combining words can change readability or meaning, so public URLs and API field names deserve a final review.
