This page is designed to help you find out whether JSONJet is good and if it is the right choice for you.
JSONJet is a local-first desktop data explorer for macOS, Windows, and Linux. It helps developers and data-focused professionals open, navigate, inspect, and export large files without switching between multiple tools.
Supported formats include JSON, JSONL/NDJSON, CSV/TSV, Excel, ODS, Parquet, SQLite databases, SQL dumps, plain text, and logs. Depending on the format, you can explore data in Tree, Table, or Raw views, search text and key-value pairs, use regular expressions, navigate to specific JSON paths, filter and sort tabular data, and inspect file structures.
JSONJet uses progressive reading to help you explore large files without first rendering the entire document. Files are processed locally: their contents are not uploaded to JSONJet's servers, and the application does not edit or overwrite your original files. SQL dumps can be inspected without executing their statements.
Whether you're debugging an API response, reviewing a CSV export, exploring a Parquet dataset, inspecting a SQLite database, or troubleshooting application logs, JSONJet brings common data-inspection workflows into one focused desktop workspace.
The Free edition is available for personal, non-commercial use without an account. A Pro license is available for commercial use and additional capabilities.
Download JSONJet and explore your data on your own computer.

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.
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.
