Working with XSLT in modern data pipelines and XML-driven systems has always been powerful… but not always easy. Tools are often heavyweight, outdated, or require local setup and complex environments. That’s why I’m thrilled to announce the launch of XSLTPlayground.com — a free, open-source, browser-based XSLT editor designed specifically for real-world use cases.
✅ No installations. No complexity. Just open your browser and transform.
🚀 Why XSLT Playground?
🔁 Real-time XSLT Transformations for Real-World Scenarios
Unlike legacy tools or limited web demos, XSLT Playground supports complex transformations involving multiple XML sources, parameterized templates, and real feedback. Whether you work on data integration, API gateways, XML-based reporting, or legacy system upgrades, this tool helps you test and iterate quickly.
🧩 Multi-Input Parameter Support
One of the biggest pain points in XSLT testing is simulating real environments. With XSLTPlayground.com, you can define multiple input sources (e.g., data feeds, configuration, or metadata), and pass them into your XSLT in a synchronized way — just like a production data pipeline.
⚙️ Automatic Parameter Synchronization
When you load a stylesheet with required parameters, the Playground automatically detects them and creates input fields for you on the side. All you need to do is fill in the values. This smart feature removes the guesswork and helps avoid runtime errors.
⚡ Performance & Optimization Insights
Need to know if your optimization is working? We display execution time for each transformation, helping you compare versions and choose the faster approach — all without deploying full systems or instrumenting code. While it’s not a benchmarking tool, the feedback is invaluable for real-time tuning.
🌐 100% Free, Web-based, and Open Source
No need to install bulky tools like Oxygen XML or run Eclipse plugins just to test a stylesheet. XSLTPlayground.com is entirely web-based, free, and built to be open and extensible. Want to contribute or host your own version? The source is on GitHub.
🖱️ Drag & Drop Support
Upload your XML or XSLT files by simply dragging them into the browser. All components — inputs, stylesheets, outputs — support drag and drop for faster iteration.
🎨 Pretty Print and Export Options
Your output is automatically pretty-printed for readability, and with just one click you can download your XSLT and transformation result, making it easy to share, archive, or import into larger projects.
🔗 Try it now: https://xsltplayground.com
Whether you’re a developer, data engineer, or working with legacy systems, this is the tool you’ve been waiting for. Say goodbye to the complexity of setting up XSLT tests and say hello to instant transformations — anywhere, anytime.
