About

Converts text between 13 case variants including camelCase, PascalCase, snake_case, kebab-case, Title Case, UPPER CASE, lower case, CONSTANT_CASE, Train-Case, Dot.Case, Sentence case, sWAP cASE, and aLtErNaTiNg cAsE. Displays all variants simultaneously in real-time with individual copy buttons for each variant and a character/word count summary.

Different programming languages enforce different naming conventions (camelCase for JS, snake_case for Python, kebab-case for CSS). Developers need to convert between conventions quickly when moving between projects or refactoring codebases without manual search-and-replace operations.

Who should use this tool?

Full-stack developers working across multiple languages, API designers normalizing field names, database administrators mapping between conventions, and anyone refactoring large codebases with inconsistent naming.

Common use cases

Convert a database column in snake_case to camelCase for a JavaScript API response
Rename Python variables from camelCase to PEP 8-compliant snake_case
Generate CONSTANT_CASE environment variable names from a plain English description
Reformat filenames from Title Case to kebab-case for URL slug generation
Create Train-Case CSS class names from a camelCase React component name
Quickly produce all possible case variants of a function name for documentation

How to Use

Type or paste your source text — all 13 case variants update in real-time as you type

Browse the grid of all variants, each clearly labeled with its case type name

Click the copy icon next to any variant to copy it to clipboard — each has its own copy button

Toggle 'Apply to Multi-Word' for camelCase/PascalCase to join or preserve spaces

Use the character/word count display to monitor input length

For bulk conversion, paste a list (one per line) — each line processed independently in a table

Examples

Input: 'hello world example' => Outputs: camelCase 'helloWorldExample', snake_case 'hello_world_example', kebab-case 'hello-world-example', and 10 more variants

Input: 'userID-field' => Outputs: camelCase 'userIdField', snake_case 'user_id_field', Title Case 'User ID Field'

Best Practices

Use the live preview to verify your chosen variant before copying — catches edge cases like leading digits
For multi-line input, process one line at a time for clean results
Use Dot.Case for config keys (NestJS, Java properties) and kebab-case for URL slugs
Remember camelCase starts lowercase, PascalCase starts uppercase — mixing them is a common bug
Review acronyms manually — the tool applies standard rules without special acronym handling

Common Mistakes

Assuming UPPER CASE and CONSTANT_CASE are the same — CONSTANT_CASE inserts underscores between words
Using snake_case where kebab-case is expected or vice versa
Not cleaning the input of special characters — @, #, $ may cause unexpected word boundaries
Forgetting Sentence case capitalizes only the first word of the entire input
Relying on swap case or alternating case for serious purposes — these are novelty formats

FAQ

Does this handle acronyms like 'HTML'?

In camelCase they become 'html', in PascalCase 'Html'. Standard rules apply.

Can I convert an entire file?

Yes, paste the whole file. For code, use single identifiers for best results.

Why are some variants identical for single words?

Single-word inputs naturally produce the same output across many variants.

Is there a way to preserve abbreviations?

Not automatically. Edit the output after conversion.
