What is SQL Formatter?
SQL Formatter beautifies and standardizes disorganized database queries into clean, readable code with consistent keyword capitalization and structured indentation. It supports major database dialects including PostgreSQL, MySQL, SQL Server, SQLite, Oracle, and BigQuery. You can format complex multi-table JOINs, subqueries, CTEs, and CASE statements with customizable tab spacing or compress queries into single-line minified strings for production deployment. Because all parsing and formatting happens locally in browser memory, your proprietary database schemas, table names, and confidential queries remain completely private.
How to Use SQL Formatter in 4 Easy Steps
Step 1
Paste your raw, unformatted, or nested SQL query into the input editor.
Step 2
Select your target SQL dialect (PostgreSQL, MySQL, SQLite, Oracle, BigQuery, or T-SQL).
Step 3
Click the Format SQL button for structured indentation, or Minify SQL for compact single-line queries.
Step 4
Click Copy to place the formatted query onto your clipboard or Download as a .sql script file.

Privacy First: 100% Client-Side In-Browser Processing
100% In-Browser Local Execution. SQL Formatter operates directly inside your browser memory using client-side JavaScript and WebAssembly. Your data is never transmitted over the internet or logged on remote servers. You can open Developer Tools (F12) Network tab to verify zero outbound network calls.
Verify it yourself: Open your browser's Developer Tools (F12 or Inspect), switch to the Network tab, and perform your action. You will observe zero outbound data uploads — your data never leaves your computer.
