Beautifying Minified Queries

Backend developers paste compressed, single-line SQL from ORM logs or query builders and get properly indented, readable SQL in one click. Supports SELECT, INSERT, UPDATE, and DELETE.

📊

Cleaning Auto-Generated SQL

Data analysts format messy queries exported from BI tools like Tableau or Looker. Consistent indentation and uppercase keywords make auto-generated SQL far easier to audit.

Stored Procedure Reviews

DBAs format stored procedures and views before committing them to version control or submitting for code review. Standardised style reduces diff noise and speeds up PR approvals.

🔗

Debugging Complex JOINs

Untangle multi-table JOIN chains by formatting them so each JOIN clause appears on its own indented line. Identifying missing ON conditions or wrong join types becomes much faster.

📝

SQL Documentation

Prepare clean, readable SQL snippets for technical documentation, runbooks, and README files. Formatted queries with uppercase keywords are far more legible for non-SQL audiences.

Frequently asked questions

How do I format a minified or messy SQL query?

Paste the SQL into the input panel and it is reformatted immediately with proper indentation, uppercase keywords, and line breaks at clause boundaries like SELECT, FROM, WHERE, and JOIN.

Does this formatter support MySQL and PostgreSQL syntax?

Yes. It formats standard SQL clauses and joins common to MySQL, PostgreSQL, and other SQL dialects, including SELECT, INSERT, UPDATE, DELETE, and JOIN statements.

Is there a query length limit for the SQL formatter?

No fixed limit. Long queries with multiple joins and subqueries format the same way as short ones, with indentation applied consistently at each clause boundary.

Will formatting change the meaning or result of my SQL query?

No. The formatter only changes whitespace, line breaks, and keyword casing for readability. It does not alter column names, logic, or query semantics.
