As a full-stack developer, I constantly found myself juggling multiple browser tabs and tools just to handle JSON data, debug API payloads, and resolve UI and backend issues. From decoding base64 strings to formatting messy JSON, comparing files, or even entire folders, the workflow was fragmented and inefficient. JSON Workbench was born out of this frustration – a single, integrated solution to streamline these daily debugging headaches.






Our powerful JSON editor provides a seamless experience for manipulating your JSON data. You can easily edit, format (minify or pretty-print), and validate JSON structures directly in your browser. This online tool ensures your data is always well-formed and readable, saving you time and preventing errors.

JSON Editor Interface
Debugging often involves comparing different versions of JSON payloads. The JSON diff tool allows you to compare two JSON structures side-by-side, highlighting differences with clarity. This feature is invaluable for identifying discrepancies between development, QA, and production environments, making your debugging process much faster and more accurate.

JSON Comparison Interface
Easily compare two files to see the differences. Our file compare tool highlights the changes between two files, making it easy to see what's new, what's been removed, and what's been modified.

File Comparison Interface
Many API payloads are Base64 encoded. JSON Workbench integrates a convenient tool to encode and decode Base64 strings instantly. This eliminates the need for separate decoding websites, allowing you to quickly access and work with your data in one place.

Base64 Encoding/Decoding
JSON Workbench now fully supports folder comparison, enabling you to analyze and identify differences across entire directories. Quickly detect missing, renamed, or modified files, and even view content-level changes across multiple files in a structured, visual interface. This tool is especially useful for developers managing large projects, version control workflows, or comparing deployment builds.

Folder Comparison Interface
JSON Workbench is completely free to use. We prioritize your privacy: all processing happens securely within your browser. No data is ever sent to our servers, ensuring your sensitive information remains confidential. Being browser-based, it's accessible from anywhere, anytime, without any installation required.
