Version History

Added

• Toolbar features: added a visible Save button plus operations for sorting object keys, converting JSON5/JSONC to standard JSON, and recursively toggling key names between snake_case and camelCase.
• Tree and tab navigation: added cursor-linked Tree View selection with automatic ancestor expansion and scrolling, one-click JSON path copying, shortcuts for pinning tabs and closing all tabs, and in-place tab renaming.
• Native desktop integration: added a custom frameless window and titlebar, integrated toolbar actions into the titlebar, and added a native macOS Window menu with shortcuts such as Move & Resize.
• Common JSON-family file support: added system file associations for common JSON formats including .json5, .jsonl, .ndjson, .jsonc, .geojson, .topojson, .har, .webmanifest, .ipynb, and .sarif.
• Interactive documentation: added a bilingual product demo and dedicated Tree/Grid View guides, refreshed README screenshots and feature messaging, and improved website navigation and responsive presentation.

Improved

• Format conversion: expanded Convert View with Properties, INI, and Markdown Table support; improved YAML/XML/TOML/CSV round trips for root arrays, empty values, escaped XML keys, and CDATA; and returned an error when CSV arrays contain non-object values instead of dropping data.
• Code generation and reverse conversion: replaced heuristic code-to-JSON conversion with bundled Tree-sitter AST parsers, preserving nested and optional structures, root arrays, and more language-specific type shapes; stabilized PHP generation, language switching, and concurrent conversions.
• Smart log data extraction and parsing: added recognition for Java/Kotlin toString, C# record, Go fmt, Python repr, Rust Debug, and JavaScript Map/Set output embedded in logs, making it possible to extract, parse, and display structured data from noisy log content for easier inspection.
• Tool-page workflows: made the JSON toolbar work across Diff, Convert, Codegen, and Schema panels; unified their titlebar styling and return actions; and isolated standalone tool-page edits from the main editor's file tabs.
• UI styling and layout: improved cursor mapping at property boundaries and line ends, query-help placement, panel colors and spacing, the default sidebar width, resize resistance and drag-to-collapse behavior, and workspace-responsive sizing for bottom panels.
• Desktop workflow: raised the default window to 1440x900 with 960x640 minimum bounds, selected the system locale by default, and suppressed browser-style context menus, selection, dragging, and zoom interactions for a more native desktop feel.
• Build and release pipeline: upgraded builds to Node.js 22 and pnpm 11, bundled Tree-sitter grammars for offline/reproducible Rust builds, stabilized CI dependency handling, and added a Windows portable ZIP package.

Fixed

• Editor interactions: fixed Monaco search-widget hover artifacts and removed the visible delay when switching themes.
• Link opening: fixed editor and resource links so they open through the native desktop opener.

Removed

• Code-generation targets: because the new AST-backed reverse-conversion workflow does not support some languages, removed the less commonly used Elm, Haskell, Crystal, Elixir, and Pike targets from code-structure and JSON conversion.

Added

• Grid View: added a spreadsheet-like view for JSON arrays and objects, with inline editing, selection handling, export support, and editor-linked highlighting.
• Tree View editing: added structured editing for keys and values, drag-and-drop reordering, value-only copy actions, and safeguards for JSON that contains duplicate keys.
• Folder sidebar: added a sidebar for opening folders, browsing JSON/JSON5 files, creating untitled JSON files, and revealing files in the system file manager.
• Tab management: added draggable tabs, horizontal scrolling for crowded tab bars, and removed the previous tab count limit.
• App updates: added GitHub release update checks, in-app update notifications, macOS update menu entries, localized update actions, and resource links.
• Website changelog pages: added public English and Chinese changelog pages.

Improved

• Large JSON performance: made large-file tab switching and Tree/Grid interactions smoother with model reuse, persistent workers, virtual scrolling, and deferred editor loading.
• Editor architecture: refactored JSON source parsing, document models, Tree/Grid data models, and worker reuse to reduce duplicate parsing work and provide a stronger base for structured editing features.
• Duplicate-key handling: preserved duplicate keys during strict JSON formatting, showed duplicate keys in structured views, and blocked ambiguous structured edits when needed.
• Log JSON extraction: improved nested log payload extraction, folded extracted previews by default, and removed the automatic repair prompt from editor flows.
• File and desktop workflows: improved JSON/JSON5 file opening, save-dialog default names, restored window bounds, single-instance file opens, macOS edit shortcuts, clipboard paste, and custom about/settings dialogs.
• Website and page styling: refined the documentation website layout, changelog pages, tool pages, theme consistency, and responsive styling across English and Chinese pages.
• Release and packaging: improved signed updater artifacts, release version validation, macOS DMG layout, Windows icon quality, and Homebrew documentation.

Fixed

• Editor state: fixed stale statistics after restoring empty tabs and improved active-tab visibility.
• macOS behavior: restored common edit shortcuts, fixed clipboard paste, preserved default app menu items, and kept app metadata visible in about/update flows.
• Global shortcuts: prevented configured shortcuts from firing multiple times and improved shortcut update consistency.
• Log JSON detection: kept standalone escaped JSON documents in the normal editor flow instead of treating them as mixed log content.
• Tab interactions: preserved reliable tab switching after drag-and-drop reordering.
• Build stability: tightened release workflows, updater metadata packaging, build-test configuration, and platform artifact handling.

Added

• Log JSON fragment visibility: enhanced log-fragment readability with clearer extraction highlighting and improved result presentation.

Improved

• Editor and tab experience: smoother language-mode consistency, better JSON/JSON5 editing continuity, and faster panel response during tab switching.
• Documentation and website polish: refreshed README and website messaging, improved feature showcases, and refined light/dark demo presentation.
• Release workflow resilience: improved release asset/build handling for more predictable packaging output.

Fixed

• Formatting and highlighting consistency: resolved several edge cases affecting JSON5 formatting and mixed-content syntax highlighting behavior.
• Interaction noise in log review: reduced distracting cursor/highlight artifacts and unnecessary prompts during log-fragment workflows.

Added

• Auto-save: add an optional auto-save setting to save modified file-backed tabs automatically.
• Mixed log-like text and JSON formatting: detect JSON, JSON5-like, escaped JSON, and repairable JSON fragments inside log-like text, keep the original editor content unchanged, and display the extracted JSON data as formatted structured results.
• Auto-numbered untitled tabs: new documents are named Untitled-1, Untitled-2, and so on for easier tab identification.
• Unit tests for log JSON extraction: cover mixed logs, multiple fragments, JSON5-like input, escaped JSON, invalid content, and braces inside strings.

Improved

• Paste normalization: auto-format pasted JSON in diff mode and standalone JSON/JSON5/escaped JSON in normal editor mode where appropriate.
• File tab workflow: prompt before closing unsaved changes, reuse an already opened file tab instead of opening duplicates, and keep destructive editor operations undoable.
• Desktop titlebar theming: align the macOS window titlebar background with the active light/dark theme.
• Shortcut registration robustness: prevent application startup failure when shortcut registration fails.

Fixed

• JSON formatting order: preserve object key order instead of sorting keys alphabetically by default.
• Async paste race: avoid overwriting newer user edits when asynchronous paste formatting finishes after additional input.

Added

• JSONPath query mode in Tree View: add a query mode switcher so users can choose between JMESPath and JSONPath directly in the Tree View toolbar.
• JSON5 syntax: The editor and Tree View support parsing and matching of JSON5 data.
• JSON tool landing pages: add dedicated website pages for JSON Formatter, Converter, Schema, and Diff.
• Search engine site verification: add site verification metadata for Google, Baidu, 360 Search, and Sogou.

Improved

• Editor highlighting: optimize JSON/JSON5 highlight feedback to improve readability during querying and navigation.
• Project website SEO: optimize page titles, descriptions, feature wording, and favicon display.
• Documentation updates: update website links and badge formatting in README, add dark-mode screenshots for code generation docs.
• Schema view details: simplify the static divider icon styling for a cleaner and more consistent appearance.

Fixed

• Desktop Monaco initialization: initialize Monaco using the bundled instance to improve desktop build reliability.
• Error icon styling: adjust the circular details of the error icon.
