SQL Formatter

SQL Best Practices

Uppercase keywords (SELECT, FROM) and newlines improve readability.

Free Online SQL Formatter

Use this tool to format messy SQL queries into clean, readable code. Standardize your database scripts instantly.

Keyword Uppercasing

Automatically capitalizes standard SQL keywords (SELECT, WHERE, JOIN) while keeping table names intact.

Smart Indent

Aligns columns and conditions perfectly. Makes long, complex queries easy to scan.

Universal Support

Works with MySQL, PostgreSQL, SQL Server, and SQLite syntax dialects.

Write Better SQL

Structured Query Language (SQL) is powerful but messy. One-line snippets from log files or ORMs are impossible to debug. Our formatter fixes that.

  • Code Review

    Paste formatted queries into Pull Requests so your team understands what the migration does.

  • Debugging Logs

    Take that 500-character error log line and turn it into a structured query you can analyze.

Technical Details

Keyword Uppercasing

SQL keywords (`SELECT`, `FROM`, `WHERE`) are case-insensitive in most engines, but convention dictacts they be uppercase to distinguish them from table and column names. Our tool enforces this automatically.

Indentation Logic

Complex queries with nested `JOIN`s or subqueries are indented to visually separate logical blocks. We use standard 2-space or 4-space indentation equivalent to improve scanability.

Dialect Support

The formatter is designed to be "dialect agnostic," meaning it works well with standard ANSI SQL as well as T-SQL, PL/pgSQL, and MySQL variants, focusing on shared syntax structures.
