Instant SQL formatting

Paste raw or minified SQL and get a clean, indented query in milliseconds. Supports SELECT, INSERT, UPDATE, DELETE, CREATE TABLE and more.

Keyword case control

Choose between UPPERCASE, lowercase or Capitalized SQL keywords to match your team's coding style guide — consistently applied to every query.

No data leaves your browser

All formatting happens client-side in JavaScript. Your SQL queries are never sent to a server — safe for sensitive schemas and production queries.

Frequently asked questions about SQL formatting

Best practices for SQL style, readability and tooling

Unformatted SQL is notoriously hard to read, especially for complex queries spanning multiple tables and joins. Consistent formatting — proper indentation, one clause per line, consistent keyword casing — makes queries easier to review in pull requests, faster to debug, and clearer to share with colleagues.

Uppercase keywords (SELECT, FROM, WHERE) are the traditional SQL convention and remain the most common in enterprise and database environments. Lowercase is gaining popularity in modern projects influenced by ORMs and query builders. Capitalize (Select, From, Where) is a compromise. Pick one style and apply it consistently — this formatter makes switching effortless.

Yes. The formatter handles standard SQL constructs including JOINs, GROUP BY, HAVING, UNION, subqueries, CASE expressions and CTEs (WITH clauses). Each major keyword starts on its own line with consistent indentation, making even deeply nested queries readable.

The formatter supports MySQL, PostgreSQL, SQLite and MSSQL labels as style hints. Since all four dialects share the same core SQL keywords, the formatting rules apply equally well to all of them. Dialect-specific functions or syntax extensions (like PostgreSQL's :: cast or MSSQL's TOP) are preserved as-is without modification.

Format and beautify SQL queries

The SQL formatter turns cluttered database queries into a clear, indented form with aligned keywords and line breaks in the right places. That makes long SELECTs, JOINs and nested subqueries far easier to understand – while writing, during code review and when debugging. The tool supports common SQL dialects and works entirely in the browser.

Common use cases

Understand complex queries: Format an inherited query with several JOINs to follow its logic step by step.
Code reviews: Bring SQL in pull requests into a consistent shape so changes are easier to check.
Clean up logs: Make a single-line query copied from a log readable again.
Documentation: Paste neatly formatted SQL into wikis, tickets or technical documents.

How to format your query

1 Paste your SQL query into the input field.
2 Choose the dialect or formatting style if needed.
3 The tool formats the query instantly.
4 Copy the result into your editor or document.

Readable SQL saves time

Well-formatted SQL reduces errors because structure and conditions become visible at a glance – especially with JOINs and WHERE clauses. Consistent formatting across a team makes reviews faster and diffs more meaningful. The tool only changes the presentation, never the logic of your query. Since nothing goes to a server, you can paste queries with sensitive table or column names without concern.
