Dadroit JSON Viewer vs European Commission JSON Validator

Dadroit JSON Viewer displays JSON in a tree so users can browse and query structured data, including large files. The desktop viewer supports text and RegEx search with highlighted results and navigation, and it can read JSON-Lines and ndjson logs. Users can load JSON responses from a URL, authenticate when needed, combine multiple files into one searchable dataset, and export a selected node or the full dataset to CSV or XML. The viewer can monitor files and refresh the view automatically when they change. Desktop downloads are listed for Windows 64-bit, macOS, and Linux 64-bit; V Web runs in a browser. Dadroit says V Web processes JSON locally without sending or storing files, responses, or tokens on its servers. The Non-Commercial plan is free for personal, educational, and open-source use, with files up to 50 MB. Standard costs $98 a year, supports commercial use, and allows files up to 2 GB. Advanced costs $198 a year, supports files up to 1 TB, and includes file union. A free trial is not offered.
