Beautify SQL queries for clarity and reviews

Copy raw SQL from logs, BI tools, or ORMs and instantly format it with consistent indentation. Clean SQL is easier to debug, safer to share, and faster to annotate during incident analysis.

Readable queries, faster insights

Large SQL statements quickly become spaghetti. The formatter aligns SELECT lists, JOIN clauses, and complex WHERE logic so reviewers can audit intent rather than whitespace. Dialects such as Postgres, MySQL, SQL Server, and BigQuery are supported with tailored keyword sets.

Switch between uppercase or lowercase keywords, choose indentation width, and preserve inline comments without blowing up spacing. If you need to hand off queries to analysts, export the beautified version with syntax-highlighting intact.

Subquery visualization
Nested SELECT statements and CTEs are indented in a tree structure so dependencies stand out immediately.
Window function care
`OVER` clauses and PARTITION definitions keep their own indentation, making analytics logic simpler to reason about.

Minify for embeds

Need to stuff SQL into environment variables or Terraform files? Toggle the minify option to collapse whitespace while preserving statement integrity. This is ideal for shipping migration scripts or obfuscated feature flags.

All processing stays in your browser, allowing you to format service-specific queries or proprietary data models on secure machines.

Copy+diff workflow
Produce both formatted and compact versions, then compare them in Diff Checker to ensure business rules never changed.
Template-ready output
Wrap queries in backticks or heredoc markers before copying so they drop seamlessly into your app code.

Teams rely on the SQL formatter for

Code reviews

Frequently asked questions

What SQL dialects are supported?

Our SQL Formatter supports all major dialects including Standard SQL, PostgreSQL, MySQL, MariaDB, SQL Server (T-SQL), SQLite, PL/SQL, and BigQuery.

Is my SQL code safe?

Yes. All formatting happens locally in your browser using JavaScript. Your queries are never sent to our servers, ensuring your database schema and logic remain private.

Can I format minified SQL?

Absolutely. Paste any minified or one-line SQL query, and the tool will instantly beautify it with proper indentation, line breaks, and keyword capitalization.

Does it fix syntax errors?

The formatter focuses on beautifying code structure. While it doesn't execute or validate your query against a database, it can help you spot syntax errors by making the code structure visible and readable.
