What this tool does
The Text Case Converter transforms input into common casing styles such as uppercase, lowercase, snake_case, and kebab-case. It helps you normalize labels, generate slugs, and align formatting across code and content. All conversions happen instantly in your browser.
When to use this tool
Use it when preparing database fields, creating URL slugs, or cleaning text for documentation. It is also helpful after cleaning inputs with Whitespace Cleaner or when preparing placeholder text generated in Lorem Ipsum Generator.
How it works
The tool splits text into words, normalizes spacing, and then applies casing rules for each output format. It preserves the original content while offering multiple variations so you can copy the exact case you need.
Example use case
You receive a list of feature names like "User Activity Report" and need URL slugs. Paste the list, convert to kebab-case, and copy the results into your routing file. If you also need database keys, grab the snake_case output from the same conversion.
Use cases
- Generate kebab-case slugs for URLs or routes.
- Normalize labels to snake_case for databases.
- Convert headings to uppercase for UI labels.
Notes & limitations
Case conversion is language-agnostic and may not handle special characters or locale-specific rules perfectly. For acronyms or product names, review the output to ensure capitalization matches your style guide. The tool is designed for quick formatting, not full editorial editing.
Punctuation, emoji, and symbols are preserved as-is, which can lead to unexpected separators in snake_case or kebab-case. If you are generating slugs for URLs, remove or replace special characters before converting to avoid invalid paths or encoding issues.
If you are converting bulk text, scan the results for double separators or leading underscores that can appear when multiple spaces are present. Running the whitespace cleaner first can reduce these artifacts and produce more consistent output across large lists.
For acronyms, review the output to preserve capitalization in final labels.
Keep a saved version of your preferred formatting rules for reuse.
