About CodersWiz
We build tools that solve real problems developers face every day.
Why We Started CodersWiz
CodersWiz began when our team of developers got fed up with jumping between different tools, sites, and apps just to format code, compare files, or generate test data. We wanted one place with all these tools - built right, fast, and free.
So we built it ourselves. No signups, no subscriptions, no tracking - just tools that work.
Whether you're comparing API responses, cleaning up legacy code, or generating test data, we've created the exact tools we wish we'd had.
Code Formatting
Clean up messy code with our formatters for JSON, XML, and more. Apply consistent styles and standards across your projects without the hassle.
Code Comparison
Instantly see every difference between code files with our visual diff tools. Perfect for code reviews, debugging, or checking what changed between versions.
Test Data Generation
Stop creating test data manually. Generate realistic datasets for your applications in seconds - from personal info to complex nested JSON structures.

Our Core Principles
Developer Experience First
We hate bloated interfaces and unnecessary complexity. Every tool we build starts with asking "What's the simplest way to solve this problem?" We test our tools on real-world code and refine them based on actual developer feedback.
Continuous Improvement
We're actively developing new tools and enhancing our existing ones. We regularly check which languages need better support, which data types are most requested, and what comparison options would help developers most. Have a suggestion? We'd love to hear it.
