The essential developer
toolkit.

A complete toolkit for JSON, code & dev workflows

In today's fast-paced development environment, having a reliable set of utilities can save hours of frustration. Whether you are a frontend engineer debugging a complex state, a backend developer verifying authentication tokens, or a DevOps specialist building automation scripts, gbkarki.com.np offers a unified platform to handle common tasks with precision.

Our suite spans JSON tooling, code editors, and text utilities — from a high-performance JSON Converter to a robust JWT Decoder. We consolidate everything into a single web application so you can skip the dozens of browser tabs and insecure third-party sites.

Mastering JSON data management

JSON (JavaScript Object Notation) is the lingua franca of the web. However, working with raw, unformatted JSON can be nearly impossible. Our JSON Converter doesn't just beautify your code; it provides deep validation and structural insights with tree, table, and raw views, plus auto-fix for common syntax errors.

• Instant validation against standard JSON schemas.
• Minification for optimizing network payloads and storage.
• Object key naming conversion (camelCase, snake_case, PascalCase) without touching values.

Code editors & automation

Prototype without leaving the browser. The HTML Editor gives you a live HTML/CSS/JS preview, and the Code Formatter beautifies and indents HTML, Java, Python, and MySQL code on demand.

Security & identity verification

Security is never an afterthought. When you are debugging authentication flows, you need to see exactly what is inside your tokens. Our JWT Decoder & Signer provides a visual breakdown of your JSON Web Tokens, highlighting the header, payload, and signature components.

Unlike other decoders that send your tokens to a server, our tool processes the data entirely in your local session. This means your sensitive claims and secret keys never touch the internet.

Explore the JWT documentation to understand how tokens are structured.

Text, data & mock API utilities

From comparing environment variables to cleaning up dirty data exports, text manipulation is a daily task. Our Diff Viewer uses advanced algorithms to identify additions, deletions, and subtle character-level changes between two text blocks. The Text Converter handles case transformations, URL encoding, and Base64 processing, while the Mock API Generator creates stateless dummy JSON responses for frontend development without a backend.

Documents & everyday utilities

Beyond dev tools, we also cover the utilities you reach for outside the IDE: an ATS Resume Builder with instant PDF export, and a QR Generator for turning any link or text into a scannable code.
