SQL 格式化工具, built by independent developers, is a Chrome extension for cleaning and structuring SQL queries inside the browser. It reformats messy SQL into readable code with beautification and minification, while preserving placeholders used in prepared statements. The tool provides in-editor syntax highlighting and quick-format controls to speed code review. Developers, database administrators, and data analysts gain a compact, browser-centered workflow for inspecting and preparing queries without leaving their current tab, aided by light and dark themes.

Handles a wide set of SQL dialects and placeholder formats

The extension supports over 15 SQL dialects, covering common and specialist syntaxes to reduce manual adjustments when moving queries between systems. Example dialects include:

• MySQL, PostgreSQL, SQL Server
• Oracle PL/SQL, MariaDB
• Spark SQL, Hive, DB2

Processes queries locally to limit external exposure

The tool uses a privacy-first design that formats SQL inside the browser, ensuring no query text is sent to external servers. This local processing model keeps sensitive statements on the user’s device and aligns with offline development workflows. Because all work happens in-browser, formatting does not require network access to a remote API, which simplifies use in restricted or air-gapped environments.

Integrates with browsing workflows and offers UI customization

The extension integrates into Chrome and other Chromium-based browsers and provides workflow conveniences such as right-click menu access and configurable keyboard shortcuts for immediate formatting. It includes clipboard management with quick copy and clear actions, a full-page editing mode for long queries, and light/dark theme options to match coding setups. These integration points reduce context switching when reviewing SQL inside web tools or documentation pages.

Practical choice for browser-based SQL work, with limited long-term history

Given generally positive user reception for its offline behavior and the inclusion of a local history that keeps the last 20 formatting records, this extension is a practical option for developers and DBAs who want fast, in-browser SQL cleanup. The 20-entry history cap makes it less suited to long-term archival or audit needs, so teams needing extended records should plan an external backup process.
