 # jsonviz
-visualize json files in the terminal
+
+`jsonviz` is a command-line tool built in Go that visualizes JSON file structures in a navigable tree format using the `termui` library. This tool is designed to help developers and data scientists quickly understand and explore the structure of complex JSON data from the terminal.
+
+## Features
+
+- **Interactive Tree View**: Display JSON files as expandable and collapsible trees.
+- **Color Coding**: Different colors for root, keys, and values to enhance readability.
+- **Keyboard Navigation**: Use keyboard shortcuts to navigate through the JSON structure.
+- **Resizable UI**: Adapt to terminal size changes dynamically.
+
+## Installation
+
+To install `jsonviz`, clone this repository and build the tool using Go.
+
+```bash
+git clone https://github.com/copyleftdev/jsonviz.git
+cd jsonviz
+go build
+```
+
+## Usage
+
+After building the tool, you can run it by specifying the JSON file you want to visualize:
+
+```bash
+./jsonviz path/to/your/file.json
+```
+
+### Keyboard Shortcuts
+
+- **Arrow Up (`k`)**: Move up in the tree.
+- **Arrow Down (`j`)**: Move down in the tree.
+- **Enter**: Expand or collapse the selected node.
+- **CTRL+C**: Exit the application.
+
+## Requirements
+
+- Go 1.15 or higher
+- `termui` library (automatically installed with go get)
+
