I built a VS Code extension to visualize JSON as graphs

Animesh Manna — Tue, 17 Mar 2026 16:46:56 +0000

Working with large JSON always felt painful—too much scrolling, hard to understand structure, and easy to lose context.

So I built a VS Code extension that converts JSON into interactive graphs inside the editor.

Now you can actually see your data instead of reading endless lines.

✨ Features:

Visual graph view for JSON

Explore nested data easily

Fast & lightweight

Works directly in VS Code

Try : https://open-vsx.org/extension/jsonviewertools/animesh-jsonviz78

It’s especially useful when working with APIs or complex responses.

Would love your feedback 🙌

MongoLens: Visualize and Edit MongoDB Documents as Graphs on Mobile

Animesh Manna — Thu, 26 Feb 2026 01:57:26 +0000

Managing MongoDB on mobile has always been painful. Most tools only show raw JSON, which becomes hard to read and even harder to understand when documents are deeply nested.

That’s why I built MongoLens — a mobile MongoDB client designed with visualization in mind.

Today, I’ve added one of the most powerful features yet: Graphical Document View with Direct Editing.

The Problem

When working with MongoDB, documents often look like this:
user
├─ profile
│ ├─ name
│ ├─ email
│ └─ address
│ ├─ city
│ └─ zip
└─ activity
├─ lastLogin
└─ devices

In raw JSON, this quickly becomes difficult to navigate — especially on mobile.

The Solution: Graph Visualization

MongoLens now lets you:

• Visualize documents as interactive graphs
• Understand nested structures instantly
• Navigate relationships visually
• Edit document fields directly from the graph

Instead of reading JSON, you see your data structure.

Why this matters

This makes MongoDB easier to:
• Debug APIs
• Explore schemas
• Understand complex documents
• Edit data faster
• Work efficiently from mobile

Especially useful when you’re away from your laptop.

Other features in MongoLens
• Connect using MongoDB URI
• Browse databases and collections
• View and edit documents
• Run queries
• JSON viewer optimized for mobile
• Biometric security lock
• Light and dark themes

Built for developers

MongoLens is designed with a developer-first mindset: fast, secure, and focused on clarity.

Graph visualization is just the beginning. More visual tools are coming soon.

I Built Structviz — A Tool to Visualize GitHub Repositories as Interactive Diagrams

Animesh Manna — Thu, 05 Feb 2026 18:27:51 +0000

Understanding a new codebase can be painful.

Folders inside folders. Files everywhere. Who touched what? Where does this module connect?

So I built Structviz — a tool that turns GitHub repositories into interactive visual diagrams so developers can explore architecture, collaboration, and structure at a glance.

What Structviz Does

Structviz helps you:
• 🔍 Visualize repositories as graphs
• 🔄 Change node directions & layouts
• ✏️ Click nodes to open and edit files
• 👥 See the last contributor with hover details
• 📊 Analyze collaborator activity with percentages & charts
• 🎨 Switch between multiple themes

The goal is simple: help developers understand complex projects faster — especially when onboarding, refactoring, or auditing architecture.

Why I Built This

I work with large repositories often, and every time I joined a new project I wished for a faster way to see the system instead of mentally mapping folders and files.

Structviz started as that idea — and slowly grew into something I now use myself.

Try It Out

You can check it here:

I’d genuinely love feedback from the dev community — feature ideas, UX suggestions, or things you think are missing.

If you maintain open-source projects, I’m especially curious whether this would help contributors onboard faster.

Thanks for reading 🙌
Happy building.

Visualize XML Files with JSON Viewer Tool

Animesh Manna — Tue, 26 Aug 2025 02:26:01 +0000

Developers often deal with data in multiple formats — JSON, CSV, YAML, and yes, XML. While JSON has become the modern standard, XML still powers many APIs, configuration files, and legacy systems. Reading XML in raw form can feel overwhelming, especially when working with deeply nested nodes.

That’s why we’ve extended our JSON Viewer Tool to support XML visualization. 🚀

Why Visualize XML?

XML is structured but not always human-friendly. Visualizing it helps you:

Quickly understand hierarchies and relationships.

Spot patterns in large or complex XML files.

Transform XML data into interactive graphs and trees for better exploration.

Compare XML with other formats (JSON, YAML, CSV) in a single workspace.

How It Works

Upload your XML file directly into the tool.

The viewer automatically parses your XML into a structured format.

Explore your data in:

Tree View: See the hierarchy clearly.

Graph View: Visualize nodes and relationships interactively.

Table View: Flatten structured XML for tabular analysis.

Use Cases

Debugging API responses from XML-based services.

Analyzing configurations (like .plist, .svg, or Android manifest.xml).

Converting XML data to JSON/YAML for modern applications.

Teaching or presenting how XML structures work with diagrams.

Final Thoughts

Whether you’re migrating from XML to JSON or just need a better way to make sense of complex XML documents, our JSON Viewer Tool makes it easier with clean visualizations

Try 👉 jsonviewer.tools uploading your XML file today and instantly turn text into diagrams.

Explore JSON in 3D – A New Way to Visualize Data

Animesh Manna — Sat, 16 Aug 2025 07:50:22 +0000

Scrolling through raw JSON is fine… until you’re dealing with deeply nested structures. That’s when it starts feeling like looking for a needle in a haystack.

To solve that, I added a 3D visualization feature to JSON Viewer Tools. Instead of just trees or tables, now you can literally explore your JSON in three dimensions.

🔥 What it does

🌐 Turns JSON into a 3D graph you can rotate, zoom, and navigate

🔗 Shows relationships visually between nested keys and values

🎮 Interactive controls to explore complex structures with ease

🖼️ Better understanding of large JSON files at a glance

💡 Why 3D?

Sometimes a tree view or flat table isn’t enough. JSON can be highly nested and interconnected, and a 3D visualization makes those relationships immediately clear. It’s like going from reading a blueprint to walking inside the building.

A JSON Viewer Browser Extension with Graphs, Search, and Image Export

Animesh Manna — Sat, 16 Aug 2025 07:45:36 +0000

Working with JSON inside the browser can get messy. Whether it’s an API response, config file, or debug output — scrolling raw JSON isn’t fun. That’s why I created the JSON Viewer Extension — a lightweight browser add-on that makes exploring JSON fast, visual, and interactive.

🔥 Features

🌳 Interactive Graph Visualization – instantly turn JSON into diagrams

🔎 Search & Highlight – quickly find keys or values inside large JSON files

➕ Zoom In / Out – explore big JSON structures without losing track

📤 Export as Image – save your graph visualization in one click

🖱️ Mouse Scroll Zoom – smooth and intuitive navigation

🎨 Simple & Clean UI – built for developers, no clutter

💡 Why I Built It

As someone who works with APIs daily, I was tired of staring at raw JSON in the browser console or using heavy tools for quick checks. I wanted something lightweight yet powerful that lives right in the browser — so I built this extension.

🌐 Try it out

👉 Available now at: jsonviewer.tools

Free to use. Simple to install.
