What is SQL formatting?
 

SQL formatting takes a query written on one long line, or with inconsistent spacing, and restructures it with
      clause breaks and indentation so the logic is easy to follow. Keywords line up, subqueries are indented, and
      conditions are laid out clearly. This tool formats SQL across MySQL, PostgreSQL, SQLite, and MSSQL dialects,
      with configurable keyword casing.

 
Why format your SQL?
 

Readable SQL is easier to debug, review, and maintain. A well-formatted query makes it obvious where the
      JOINs are, which conditions belong to which clause, and how subqueries nest, all of which reduce mistakes. In
      a team, consistent formatting also makes code reviews faster and version-control diffs cleaner, since
      changes are not buried in reformatting noise.

 
Keyword casing and dialects
 

A common convention is to uppercase SQL keywords (SELECT, FROM, WHERE) while keeping table and column names
      in their natural case, which makes the structure stand out. Different database systems add their own keywords
      and syntax, so choosing the matching dialect helps the formatter handle dialect-specific features correctly,
      including complex statements and stored procedures.

 
Your queries stay private
 

Formatting happens entirely in your browser. The SQL you paste is never sent to a server, so it is safe to
      format queries that reference real schema, table names, or business logic you would not want to share. Keep
      your formatted queries in version control to maintain a consistent style across the codebase.

Frequently Asked Questions
 
 
 
  What is SQL formatting?   
 SQL formatting adds consistent indentation, line breaks, and keyword casing to SQL queries, making them easier to read, review, and debug. 
 
  Does this SQL formatter support stored procedures?   
 Yes, the formatter handles most standard SQL constructs including subqueries, CTEs, and multi-statement scripts. 
 
  Which SQL dialects are supported?   
 MySQL, PostgreSQL, SQLite, Microsoft SQL Server (MSSQL), and Generic SQL are all supported. Dialect selection affects keyword handling and specific syntax rules. 
 
  Is my SQL query sent to a server?   
 No. All formatting happens locally in your browser. Your queries are never transmitted or stored. 
 
  Why should I format my SQL?   
 Formatted SQL is significantly easier to read, debug, and review in code reviews. It also helps identify structural issues like missing JOIN conditions or incorrect clause ordering.
