FormJSON allows you to visually create and edit complex JSON files using an intuitive form-based interface seamlessly integrated into VS Code.
Features
Intuitive GUI Editing: Edit deeply nested JSON objects and arrays using clean, structured form fields instead of raw text.
Auto-Resizing Inputs: Text areas automatically adjust their height based on your content, eliminating cramped editing spaces.
Multi-Language Support: Fully functional across diverse character sets (Japanese, English, Chinese, Korean, etc.).
Real-time Synchronization: Changes made in the GUI are safely and instantly reflected in the raw JSON file, fully supporting VS Code's native Undo/Redo history.
Usage
Open any .json file in VS Code.
Open the Command Palette (Cmd+Shift+P on Mac / Ctrl+Shift+P on Windows).
Type and select FormJSONで開く (Open with FormJSON).
The GUI editor will open in a split panel, ready for editing.
