Technical Specs

Supports common SELECT, INSERT, UPDATE, DELETE, JOIN, WHERE, GROUP, ORDER, UNION, LIMIT, comments, and quoted values up to 1 MB.

Readable SQL is reviewable SQL

Consistent clause breaks and keyword casing make joins, filters, aggregation, and ordering easier to inspect before a query reaches production.

What is SQL Formatter?

SQL Formatter reorganizes query text into consistent clause breaks and indentation without connecting to a database. Developers and analysts can make joins, filters, subqueries, grouping, and ordering easier to review, or minify a statement for transport and logging.

How to use SQL Formatter

1.Paste the SQL statement into the input editor.
2.Choose the preferred keyword case and formatting or minification mode.
3.Format the query, then inspect clauses, parentheses, comments, and quoted values.
4.Copy the result and test it safely against the intended database environment.

Frequently asked questions

Does the SQL formatter run queries against a database?

No. It only transforms the supplied text and has no database connection or credentials.

Which SQL dialects can be formatted?

Common syntax shared by MySQL, PostgreSQL, SQLite, and SQL Server works well, while highly vendor-specific procedural statements may need manual review.

Will formatting change quoted strings or identifiers?

The formatter avoids keyword-case changes inside recognized quoted content, but important production statements should still be compared before execution.

Are SQL comments kept when formatting?

Formatting can retain useful comments, whereas minification may remove comments to reduce output size.

Can formatting fix an invalid SQL query?

No. Readable layout can expose a mistake, but it does not validate schema names, data types, permissions, or database-specific semantics.
