Changelog

Every released version of Prettify and what changed in it.

0.7.0

August 8, 2026Latest

A blog, opening with three posts: how the jq engine works, the four ways JSON.parse quietly corrupts numbers, and a jq tutorial built from 28 worked examples.
Three new guide pages, on editing a JSON file, on the tree viewer, and on the syntax checker.
Full keyboard control of the tree and the table: move with the arrow keys, edit with F2, cancel with Escape, and get your place back when you leave a control.
Long table cells open an inspector that shows the whole value, selectable, with a Copy button.
The app now says when the connection drops and when it returns.

Large documents parse, search, and export away from the main thread, so the app keeps responding. The work reports progress and can be cancelled.
The home page has a new design: a data-motif hero in place of the cursor spotlight and the scroll fade-ins, feature cells that show a tree sample and a jq result instead of describing them, a strip of measured figures, and footer tool links grouped by task.
The home page opens the web editor as its first action, with the download next to it, and it states more plainly what Free covers and what Pro adds.
An empty Dashboard leads with one action, trying a JSON example, and keeps the other formats as light links beside it.
Settings are grouped into a clearer order.
The locked Diagram view shows a still preview instead of a live canvas, so it costs nothing to draw before you upgrade.
Creating a short link for a large document asks first, and states where the data goes, how large it is, that it becomes public, that it is kept for a year, and how to revoke it.
Opening a document from history confirms by naming the document you opened.

jq reads array and string slices, foreach, and $variables inside string interpolation. Slices also work through path, getpath, setpath, and del.
Searching a table built from nested arrays filters, sorts, counts, and steps through results against the same rows. The count and the active result used to disagree with what you saw.
Table columns drawn from nested data show their full path.
Toolbar buttons have names for screen readers, a visible focus ring, and tooltips on hover and on focus.
The link, paste and repair, and history dialogs hold focus inside themselves, hide the page behind them from screen readers, and return focus to the control that opened them.
The navigation shared by the app pages fits a narrow window.
A denied clipboard permission lands you on a paste surface instead of doing nothing.
The site states the real count of jq built-in functions, 122, in place of a stale "90+".

A changelog page listing every release. Every footer links to it, and the download page links straight to the notes for the version you are running.

Table view no longer crashes on a CSV row that carries more fields than the header. Those rows render again, with their warnings intact.
A view that hits an error now recovers when you switch document, tab, or format, instead of staying broken for the rest of the session.
Reopening the app in a new browser session restores each document in the format it was written in, rather than treating everything as JSON.
YAML merge keys resolve into the keys they point at, so Docker Compose, GitLab CI, and Rails configuration files read as written. Dates and yes / no still stay as text.
jq now tells you when arithmetic on a very large number loses precision, instead of returning a rounded result with no signal.
A new untitled tab no longer takes a number that another tab already uses.
The active tab scrolls into view when it changes, so a narrow window no longer hides it behind the pinned controls.
Pro access is confirmed with the licensing service once per browser session, so a license that is no longer valid is revoked instead of trusted from local storage.
The paste dialog is announced correctly to screen readers, and the jq demo on the home page is marked as a Pro feature.

Collapsing sections no longer clip their contents while animating open or closed.

July 23, 2026

Motion throughout the app: panels, dialogs, and view switches animate in and out instead of appearing instantly.
Animated counters, native accordions, and reversible transitions that follow your pointer back when you change direction mid-gesture.

The desktop app can activate a Pro license again. Packaged builds were sending an origin the licensing service did not recognize.
Renaming a document now updates the tab, the header, and its history entry together instead of leaving them out of sync.
Restored the right-click menu on tabs.
Fixed a crash in split view, several cases where errors were swallowed silently, and a handful of privacy and worker issues found during a QA pass.

July 10, 2026

Export from every view, not just the tree. Raw text, tables, charts, and diagrams each export in the formats that suit them.
JSONL and NDJSON files are detected and opened automatically, presented as JSON.
Batch processing: format or convert many files in a single pass.
Redesigned editor toolbar, with controls grouped and labeled.

Twelve new tool pages, per-route metadata, and prerendered HTML for a faster first paint.

July 8, 2026

First public release.

Five formats: JSON, YAML, CSV, XML, and Mermaid, with automatic detection and conversion between them.
A view for every shape of data: tree, syntax-highlighted raw text, sortable and editable tables, charts, and interactive node diagrams.
Query engines built in: a custom jq engine for JSON and YAML, SQL for CSV, and XPath for XML.
Versioned document history with search, filtering, bulk actions, storage insights, and import and export.
Multiple tabs, a command palette (Cmd+K), regex find and replace, and bookmarks with a navigable path bar for deeply nested data.
Semantic diff with change navigation, JSON Patch export, and three-way merge for JSON and YAML.
Type generation from any document: TypeScript, Go, Kotlin, Rust, and JSON Schema.
JSON Schema validation, with errors rendered directly onto diagram nodes.
JSON repair for MongoDB types, Python and JavaScript literals, comments, and JSONP.
Lossless number handling: long integers and high-precision decimals survive a round trip byte for byte.
Share links, with a shortener for Pro accounts.
A native macOS desktop app: file associations, a prettify:// URL scheme, Services, Raycast, and Quick Look integration, signed, notarized, and self-updating.
An MCP server and REST API for creating Prettify links and transforming data.
Split-view side-by-side comparison for Pro accounts.
18 color themes.
