JSON Studio1.0.5
Publisher Description
JSON Studio is a private, lossless workspace for JSON.
Most JSON tools either choke on big files, silently mangle your numbers, or send your data to a server. JSON Studio does none of that. It is a native desktop app built for speed and correctness: open a half-gigabyte file and start navigating immediately, knowing that what you see is byte-for-byte what is on disk. Everything runs on your own machine - no accounts, no uploads, no analytics, no network calls - making it safe for proprietary, regulated or personal data.
What you can do:
- Browse huge files smoothly with a virtualized tree and raw view that stay responsive on documents up to 500 MB, with collapse/expand, expand-to-depth, type and item-count badges and full keyboard navigation.
- Trust your data: big integers, high-precision decimals, key order and the exact original text are preserved losslessly - nothing is rounded, reordered or reformatted.
- Find anything fast: search across keys and values with case sensitivity, whole-field matching, regular expressions and subtree scoping, then jump straight to a match in the tree.
- Query with JSONPath: run RFC 9535 expressions with per-document history, execution timing, result counts and export to JSON or JSONL.
- Compare two documents with a structural diff (key order ignored) that matches arrays by index or by a key field and highlights what was added, removed or changed.
- Work with JSONL / NDJSON as a virtualized table with selectable columns, field statistics and invalid-row highlighting.
- Preview embedded images: string values that are data:image URIs or base64 (PNG, JPEG, GIF, WebP, SVG) can be viewed inline.
- Format and export: copy pretty-printed or minified JSON, or save the re-serialized document in one click.
- Stay in flow with tabs, remembered sessions, live reload when a file changes on disk, a node detail panel with copyable path and value, and System/Light/Dark themes.
A portable Windows build is also available: it runs without installation and keeps its settings beside the executable. JSON Studio is free and open source (MIT) and available for Windows, macOS and Linux.
