Quick answer

How to use the free SQL Formatter

To format and beautify SQL queries for free, paste your raw SQL into the editor. It automatically applies proper clause indentation, normalizes keyword casing to UPPERCASE, and formats subqueries for PostgreSQL, MySQL, BigQuery, and SQLite locally.

Free online SQL formatter & query beautifier

Beautify, format, and indent raw SQL queries for PostgreSQL, MySQL, Google BigQuery, SQLite, MariaDB, and MS SQL Server (T-SQL). Standardize query indentation, enforce uppercase keyword conventions, and minify production queries with 100% private in-browser AST parsing.

How to format SQL queries online

  • Paste your unformatted SQL query into the input editor or load a sample CTE query.
  • Choose your target SQL dialect (PostgreSQL, MySQL, BigQuery, SQLite, or Standard SQL).
  • Select your keyword casing preference (UPPERCASE, lowercase, or preserve original).
  • Set indentation to 2 spaces, 4 spaces, or Tabs.
  • Click Copy to clipboard or Download as a formatted .sql file.

Why use client-side SQL formatting

Enterprise database queries frequently contain proprietary business logic, internal table schemas, and confidential analytical formulas. Online SQL formatters that transmit queries across the internet pose security and compliance risks. ToolCrix parses and formats queries strictly within your local browser JavaScript engine.

Key features & benefits

  • Multi-dialect intelligence: handles complex CTEs, window functions, and nested subqueries.
  • Uppercase keyword enforcement: standardizes SQL keywords for clear team readability.
  • Minification mode: strips comments and extra whitespace for compact query execution.
  • Enterprise security: zero queries or database schemas are ever transmitted over the network.
Questions

Frequently asked questions

Is my SQL query or schema sent to any external server?

No. The SQL tokenizer and formatter operate 100% client-side in your web browser. Proprietary database queries, table names, and internal business logic are never logged or transmitted over the internet.

Which SQL dialects are supported?

ToolCrix supports Standard SQL, PostgreSQL, MySQL, Google BigQuery, SQLite, MariaDB, and Microsoft SQL Server (T-SQL).

Can I convert all SQL keywords to uppercase?

Yes. Set the Keywords dropdown to 'UPPERCASE' to automatically standardize keywords like SELECT, FROM, WHERE, GROUP BY, and JOIN into clean uppercase syntax.

Can I minify my SQL query?

Yes. Check the 'Minify SQL' option to strip comments and redundant whitespace, producing a compact single-line query ideal for embedding in application code or URL parameters.

How does it handle complex CTEs and window functions?

The formatter cleanly indents Common Table Expressions (`WITH ... AS (...)`), window partitions (`OVER (PARTITION BY ...)`), and multi-level subqueries for crystal-clear readability.
