JSON Viewer

JSON Viewer

JSON Viewer is a lightweight, free software tool that enables users to view and edit JSON files in a straightforward and easy-to-use manner. It was written in C++ by Mihai (bdmihai) using the Qt framework and the QJson library, and it provides a simple way to inspect the structure of JSON data without a full development environment. The program is aimed at quick viewing of configuration files, API responses and other JSON documents on Windows.

JSON Viewer provides an easy-to-read, user-friendly interface for viewing and analyzing JSON data.

Features:

1. Simple Graphical User Interface: JSON Viewer has a plain window with a text editor on the right and a "Json View" panel on the left, so users can inspect JSON data with just a few clicks.

2. Syntax Highlighting: The program highlights the syntax of JSON documents, making keys, values and the overall structure easier to read.

3. JSON Parsing: The QJson library parses the document and maps JSON objects to QVariantMap and JSON arrays to QVariantList instances, which are then shown in the tree.

4. Tree View: JSON Viewer displays JSON data in an expandable tree with Name and Value columns, allowing users to quickly navigate through nested objects and arrays.

5. Text Editing: The document can be edited directly in the text pane, with Cut, Copy and Paste commands in the Edit menu (Ctrl+X, Ctrl+C and Ctrl+V).

6. File Handling: The File menu lets users create a new document, open an existing JSON file, save it or save it under a new name (Ctrl+N, Ctrl+O and Ctrl+S).

7. Dockable Panel: The Json View panel can be detached from the main window as a floating panel or closed when only the text is needed.

8. Help: The Help menu contains a help entry and About boxes for the program itself and for the Qt framework it is built on.

9. Version: The Windows build shown in the screenshots is JSON Viewer 1.0.1, developed with the Qt 4.8.1 framework.

10. Source Code: The source code of the project is published on GitHub, so developers can study it or build the program themselves.

11. Platform Support: A ready Windows build is available; because Qt is cross-platform, the same code can also be compiled for Linux and Mac OS.

Conclusion

JSON Viewer is a handy tool for developers and analysts who need to quickly open and inspect JSON data. The tree view and syntax highlighting make nested documents easy to read, while the text pane allows quick edits. It is a basic viewer without search or comparison tools, and the project has not been updated for years, but for simple viewing tasks it remains small and straightforward.
