SQL Formatter & Beautifier
Format and beautify SQL queries with dialect support
Frequently Asked Questions
What does the SQL formatter do?
The SQL formatter rewrites compressed or messy queries with consistent indentation, aligning keywords, clauses, JOINs, and subqueries so complex statements become easy to read. It supports SELECT, INSERT, UPDATE, DELETE, CTEs (WITH), and deeply nested subqueries.
Which SQL dialects are supported?
Standard SQL, MySQL, PostgreSQL, SQLite, BigQuery, Snowflake, Redshift, and more. Dialects differ on keywords (LIMIT / OFFSET vs TOP), quoting, and data types — picking the right one gives the most accurate formatting.
Why does the formatted SQL not look the way I expected?
Typical causes: the wrong dialect so dialect-specific keywords get downgraded, mixed ASCII/full-width quotes, unsupported comment styles (-- vs #), or missing semicolons causing multiple statements to merge. Check dialect and validity first.
Will the formatter change my query semantics?
Only whitespace and newlines change. Keyword/identifier case can be unified per config (e.g., uppercase keywords), but the query's behavior is preserved — no added LIMIT, no rewritten JOIN. For actual query tuning, use EXPLAIN and profiling tools.
Can I paste business-sensitive SQL safely?
Yes. Formatting runs entirely in your browser; table names, columns, and WHERE predicates never leave your device, so production queries are safe to paste.
How do I reuse the formatted output?
Copy with one click and paste back into your IDE, DBA tool, or PR review. Use Minify to collapse SQL to a single line for logs or config. To share with teammates, screenshot or paste the formatted text directly.
