What Is SQL Formatting?

SQL formatting transforms raw or compressed SQL queries into well-indented, consistently styled code with proper keyword capitalization and aligned clauses. Readable SQL is easier to debug, review, and maintain, especially for complex joins, subqueries, and CTEs. Our formatter processes your queries entirely in the browser, making it safe to format proprietary database queries without exposing them to any external service.

How to Use SQL Formatter

  1. Paste your SQL query

    Paste your raw SQL query into the input area or upload a .sql file.

  2. Choose formatting options

    Select your preferred indentation style, keyword case (UPPER or lower), and dialect.

    Click Format to beautify the query, then copy the result or download the formatted file.

Frequently Asked Questions

Does the formatter support stored procedures and PL/SQL?

The formatter handles standard SQL statements including SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, and common procedural extensions. Complex dialect-specific procedural code may have limited support depending on the SQL dialect selected.

Will formatting change the behavior of my SQL query?

No. Formatting only changes whitespace, indentation, and letter case of keywords. The logical structure and execution behavior of your query remain exactly the same.

Can I format multiple SQL statements at once?

Yes. Paste multiple SQL statements separated by semicolons and the formatter will beautify each one individually, maintaining proper separation between statements.
