Developer Questions
Which case format should I use for variable names?
JavaScript/TypeScript: camelCase (myVariableName)
Python: snake_case (my_variable_name)
Constants: CONSTANT_CASE (MY_CONSTANT)
URLs: kebab-case (my-page-slug)
File paths: Path/case (my/file/path)
Can I use this for API naming standards?
Absolutely. API designers use ToolsMatic to normalize: JSON key naming (camelCase), database column names (snake_case), configuration constants (CONSTANT_CASE), and REST endpoint slugs (kebab-case).
What about code style guides?
ToolsMatic converts to any industry convention: Python PEP 8 (snake_case), Google style (camelCase), Go (camelCase), Rust (snake_case), Java (PascalCase), C++ (CONSTANT_CASE for macros). Enforce consistency across teams.
Content & Writing Questions
How do I convert headlines to title case?
Click the "Title Case" button. ToolsMatic capitalizes the first letter of each major word (excluding articles and prepositions). Perfect for headlines, blog titles, and document headings.
Can I preserve specific word capitalization?
Use "Sentence case" to preserve proper nouns and internal capitalization while normalizing the start. For maximum control, manually edit after conversion.
What's the difference between Title Case and Sentence case?
Title Case: Every Major Word Is Capitalized (good for headlines, article titles)
Sentence case: Only the first word is capitalized. Like normal sentences. (better for descriptions)
Features & Keyboard Shortcuts
What keyboard shortcuts are available?
⌨️ Ctrl+Enter = Convert text, Ctrl+C = Copy result, Ctrl+A = Select all input, Ctrl+D = Clear all. Power users can work entirely hands-off from the mouse.
How do I save favorite conversions?
Click the "⭐ Save as Favorite" button or press Ctrl+S. Store up to 50 frequently-used conversions (with their settings) for instant access later.
Where is my history stored?
Your last 20 conversions are automatically saved to your browser's local storage. Visit the "⏱️ History" tab to reload any previous work. History is stored only on your device—never uploaded.
Privacy & Performance
Is my text uploaded to any server?
Never. All conversions happen 100% locally in your browser. Your text, your history, and your favorites never leave your device. Zero network calls, zero tracking, zero uploads.
Why does ToolsMatic perform better than cloud-based tools?
Because we process everything in your browser with JavaScript, there are zero server round trips and zero network latency. Conversions happen instantly, even on slow connections. Perfect for air-gapped environments and offline work.
Can I clear my history and favorites?
Yes. Simply clear your browser's local storage or use the "Clear History" function in the settings menu. All personal data is deleted immediately.
Troubleshooting
The conversion isn't giving me the exact format I need?
ToolsMatic's 15+ formats cover 95% of use cases. For edge cases, convert to the closest format, then manually edit the remaining characters. Use the History feature to quickly reload close conversions.
Why doesn't the camelCase button create camelCase from my text?
Make sure your input text is separated by spaces, hyphens, or underscores so ToolsMatic can identify word boundaries. For unseparated text like "HelloWorld", switch to "Sentence case" first, then camelCase.
What should I do if clipboard copy fails?
Check that your browser has "Clipboard" permissions (usually granted automatically). Try refreshing the page. If all else fails, manually select the output text and copy (Ctrl+C).
Integrations & Workflow
Can I send text to other ToolsMatic tools?
Yes! Click "Send to Word Counter", "Send to Text Diff", or "Send to Markdown Previewer" to instantly handoff your converted text to other tools without copying/pasting.
How do I use this in my development workflow?
Bookmark ToolsMatic. When you need to normalize variable names, convert between snake_case and camelCase, or bulk-update database column naming conventions, open the tool, paste, convert, copy, done. Usually takes 10 seconds.
Does this work with my code editor?
Yes. Most code editors support copy/paste workflows. Convert in ToolsMatic, copy (Ctrl+C), go to your IDE and paste (Ctrl+V). Some developers install VS Code extensions that call ToolsMatic's conversion logic.
Advanced Questions
Can I convert mixed case like "myVarName" to other formats?
Yes. Mixed case input works perfectly. ToolsMatic detects word boundaries from camelCase, PascalCase, snake_case, and kebab-case, then converts to any other format. E.g., "myVariableName" → "MY_VARIABLE_NAME" → (my-variable-name)".
What happens to special characters during conversion?
Most case formats preserve special characters (@, #, &, =) as-is. For web-safe formats like kebab-case and Path/case, special characters are stripped or converted. The preview shows the exact result before you commit.
Can I use this for batch processing CSV files?
Absolutely. Paste entire CSV data with one column containing text to convert. Then use "Batch Mode" to convert each line independently. Export as CSV and import back to your spreadsheet.
Is there a command-line version?
Currently, ToolsMatic is web-based for maximum accessibility. For CLI workflows, you can fork the source code from our GitHub, customize it, and build a CLI tool. Community contributions are welcome.
Can I contribute case formats or improvements?
Absolutely! ToolsMatic is open to feature requests and contributions. Contact us at support@toolsmatic.me with your ideas or join our GitHub discussions to propose new case formats.
