Dadroit JSON Viewer
What it is
Dadroit JSON Viewer displays JSON in a tree so users can browse and query structured data, including large files. Its desktop viewer supports text and RegEx searches, highlights results, and provides navigation between matches. It can read JSON-Lines and ndjson logs, load JSON responses from a URL with authentication when needed, and combine multiple JSON files into one dataset for searching. Users can export a selected node or the whole dataset to CSV or XML, in formatted or minified form. The viewer can monitor files and refresh the display when they change. Desktop versions are listed for Windows 64-bit, macOS, and Linux 64-bit; V Web runs in a browser. Dadroit says V Web processes JSON locally and does not send or store files, API responses, or tokens on its servers. The free Non-Commercial license covers personal, educational, and open-source use with files up to 50 MB. Standard costs $98 a year and allows commercial use with files up to 2 GB. Advanced costs $198 a year, supports files up to 1 TB, and includes file union. No free trial is offered.
