As answered by people managing JSONJet and Comapi.
JSONJet's answer
JSONJet combines large-file exploration, multi-format support, and local-first processing in one desktop application. Instead of switching between separate tools, users can inspect JSON, spreadsheets, Parquet datasets, SQLite databases, SQL dumps, text files, and logs in one place.
Its Tree, Table, and Raw views provide different ways to explore data, while search, regular expressions, direct navigation, filtering, and export tools help users find and work with relevant information.
Privacy is another important part of the design: file contents stay on the user's device, original files are never modified, and SQL dumps are inspected rather than executed.
JSONJet's answer
Choose JSONJet if you regularly work with different data formats and want a focused desktop tool instead of maintaining several separate viewers.
JSONJet supports a broad range of structured and text-based files, offers multiple viewing modes, and includes practical tools for searching, navigating, sorting, filtering, and exporting data. Its local-first approach is particularly useful when inspecting application logs, database backups, API responses, or other files that should not be uploaded to an online service.
The Free edition lets users evaluate the application for personal, non-commercial use, while a Pro license is available for commercial use. The best choice depends on your workflow, but JSONJet is designed to make everyday data inspection simpler and more convenient.
