JSON Beautify - JSON 格式化与验证工具

JSON Beautify is a practical browser extension for anyone who regularly works with JSON and wants a faster, cleaner workflow directly in the browser. Based on the provided package details, it combines several JSON-focused tools into a single workspace, making it useful for reading API responses, checking structured data, cleaning pasted snippets, and converting raw JSON into a more readable form without needing a separate application. Instead of limiting itself to basic formatting, the extension provides an editor-style environment where JSON can be pasted, typed, inspected, transformed, and compared in multiple ways.

The extension supports beautifying JSON with configurable indentation, validating syntax, and minifying content into a compact single-line format. It also provides structural insights such as line count, byte size, number of keys, and nesting depth, helping users quickly understand the complexity and size of a document. For larger or deeply nested data, the included tree view offers a clearer way to navigate objects and arrays through expandable and collapsible nodes. This can make it easier to inspect specific branches of a JSON document without scanning through a large block of text.

A notable strength described in the package is its handling of more than strictly valid JSON. The formatting and validation logic attempts to repair common issues before parsing, including comments, trailing commas, and unquoted object keys. This makes the extension useful not only for strict JSON documents, but also for developer-oriented snippets and configuration-like content that is close to JSON but not perfectly compliant. In addition, utility tools for escaping and unescaping text are included, which can help when preparing strings for JSON values or decoding escaped content during development and debugging.

The extension also works at the page level. It can detect JSON-like pages automatically, read JSON content from the current page, and enhance raw JSON pages by replacing plain text with a more readable beautified presentation. On detected JSON pages, users can switch between the original and formatted view, copy the beautified output, and download it as a JSON file. Context menu support adds another layer of convenience by allowing selected text to be formatted, minified, validated, or copied as beautified JSON with quick right-click actions. There is also a page-level option to beautify the current page’s JSON directly.

Settings are available through an options page, where users can define default indentation style, tree expansion depth, key sorting behavior, syntax highlighting, and automatic JSON detection on pages. According to the package details, these preferences are stored locally so the chosen workflow remains consistent each time the extension is used.

Key Features:
- JSON formatting with configurable indentation using 2 spaces, 4 spaces, or tabs.
- JSON validation with error reporting that can include position, line, column, and nearby content snippets.
- JSON minification for producing compact single-line output.
- Tree view for exploring nested objects and arrays with expandable and collapsible nodes.
- Automatic detection of JSON pages, with beautified in-page rendering and quick actions.
- Text escape and unescape utilities for JSON-related workflows.
- Side-by-side JSON comparison that detects differences in structure, types, values, missing keys, and array lengths.

How It Works:
1. Install the extension and open its main panel from the toolbar, or access tools through the context menu on selected text or pages.
2. Paste or type JSON into the editor, or read content from the current page using the built-in page-reading feature.
3. Choose formatting preferences such as indentation style and optional key sorting.
4. Run actions such as beautify, validate, minify, build a tree view, escape or unescape text, or compare two JSON documents.
5. Review the output along with available statistics such as line count, byte size, total keys, and nesting depth.
6. Copy the processed result, download it as a JSON file, or send the formatted output back into the editor for further editing.
7. Adjust default behaviors in the settings page, including syntax highlighting, automatic JSON detection, and tree expansion depth.

Privacy: - No personal data collected. The provided package details indicate that settings are stored locally in the browser, JSON processing happens locally, and processed data is not uploaded to third-party servers. The all-sites access is described as supporting context menu actions and current-page JSON reading across websites.
