How to Format SQL Online
Unformatted SQL queries — especially generated ones from ORMs or query builders — are nearly impossible to read when they're a single line of text. A SQL beautifier adds proper indentation, line breaks, and keyword capitalization so you can understand the query structure at a glance.
This is essential when debugging slow queries from your database's query log, reviewing SQL in pull requests, or reverse-engineering what an ORM is actually generating. Paste in a compact query and get a well-structured, readable version. The formatter handles SELECT, INSERT, UPDATE, DELETE, CTEs, subqueries, and joins.
Everything runs in your browser — important when you're formatting queries that contain table names, column names, or conditions that reveal your database schema. No data is sent to any server.
Tips
- Capitalize SQL keywords (
SELECT,FROM,WHERE) for readability — it's the most common convention in production codebases. - Put each column in a
SELECTlist on its own line to make diffs cleaner in version control. - Use CTEs (
WITHclauses) instead of deeply nested subqueries — they're easier to read and debug. - Format your ORM-generated queries to verify they're doing what you expect — you might catch missing indexes or N+1 patterns.
