Text & Encoding Tools
Convert case, encode/decode strings, test regexes, compare text, and generate tokens like UUID/JWT. Each tool has its own page with benefits, use cases, a field guide, and the tool UI.
Why Use These Tools?
Case conversion: Transform text between upper, lower, camel, snake, and kebab case.
Secure encoding: Safely encode data for URLs, HTML, and Base64 transmission.
Pattern testing: Build and test regex patterns with instant feedback.
Token generation: Create UUIDs and work with JWTs for authentication.
Common Use Cases
Variable Naming
Convert text to camelCase, snake_case, or kebab-case for code.
API Development
Encode query parameters and decode Base64 payloads.
Data Validation
Test regex patterns before using them in production code.
Authentication
Decode and verify JWTs during development and debugging.
How to Use These Tools
- Select a tool: Pick the text tool that matches your task.
- Enter your text: Paste or type the text you want to process.
- Copy the result: Get the transformed output instantly.
Tip: Use the Text Diff tool to compare two versions of code or content side by side.
