SQL Beautifier Online

Format any SQL dialect with consistent indentation — universal SQL formatting tool

What Is SQL Beautification?

SQL beautification transforms raw or poorly formatted SQL queries into consistently structured, readable code. The beautifier adds strategic line breaks, indents clauses and sub-clauses, normalizes keyword casing (typically uppercase for SQL keywords, lowercase for identifiers), aligns related elements, and applies consistent spacing around operators. The result is SQL that reads like well-organized prose rather than a dense wall of text.

SQL beautification matters for query readability during development and debugging, code review quality where reviewers need to quickly understand query intent, documentation clarity for queries shared across teams, and version control hygiene where consistent formatting prevents cosmetic-change noise in diffs. A universal SQL beautifier handles common SQL constructs that work across all major databases: SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER, JOINs, subqueries, and aggregate functions.

How to Beautify SQL Queries

1. Paste your SQL query into the input editor
2. Select formatting options: keyword case (uppercase/lowercase), indentation size, and line width
3. Click Beautify to format the query with consistent styling
4. Review the formatted output — each clause is on its own line with proper indentation
5. Copy the beautified SQL for use in your codebase, documentation, or database tool

Why Use PinusX SQL Beautifier?

PinusX beautifies your SQL with 100% client-side processing in your browser. Your database queries — containing table names, column structures, conditions, and business logic — never leave your device. SQL queries can expose your entire data model and access patterns to anyone who intercepts them. In November 2025, jsonformatter.org leaked over 80,000 user credentials processed through their servers. PinusX prevents this by running the formatter locally in your browser tab using JavaScript, with no server communication. Beautify any SQL query with complete confidence in your data privacy.

Frequently Asked Questions

Does the beautifier work with all SQL databases?

The beautifier handles standard SQL syntax that works across MySQL, PostgreSQL, SQL Server, Oracle, SQLite, and other databases. For database-specific syntax (like MySQL backticks or PostgreSQL JSONB operators), use the dialect-specific formatters. The universal beautifier focuses on ANSI SQL constructs common to all databases.

Should SQL keywords be uppercase or lowercase?

Both conventions are widely used. Uppercase keywords (SELECT, FROM, WHERE) is the traditional convention and provides clear visual separation between SQL structure and identifiers. Some modern teams prefer lowercase for consistency with their programming language style. Our tool lets you choose either convention.

Can I customize the indentation style?

Yes. Choose between 2 spaces, 4 spaces, or tabs for indentation. You can also configure the line width limit and whether to place commas at the beginning or end of column lists. These options let you match your team's SQL coding standards.

Does beautifying affect query performance?

No. SQL formatting is purely cosmetic — whitespace and casing have no effect on query execution plans or performance. The database parser ignores formatting when compiling queries. A minified single-line query and a beautifully formatted multi-line query produce identical execution behavior.
