What SQL Formatter does

Format or compact SQL and normalize keyword case for easier review without connecting to a database.

Worked example

Input

select id,name from users where active=1

Result

SELECT id, name FROM users WHERE active = 1

How it works

The formatter tokenizes recognized SQL keywords, identifiers and clauses, then applies indentation and case options. It does not execute or optimize the query.

Developer workflows

  • Review generated queries
  • Normalize SQL before code review
  • Make long joins and clauses easier to inspect

Security and compatibility checks

  • SQL dialects differ in functions, quoting and syntax.
  • Formatting does not prevent SQL injection.
  • Test queries and execution plans in the target database before production use.

Frequently asked questions

Does this tool run my SQL?

No. It only transforms the text in your browser.

Can formatting fix a syntax error?

It may reveal an error more clearly, but it does not guarantee valid SQL for your database dialect.
