SQL Formatter & Minifier

Beautify messy SQL queries with dialect-aware formatting for PostgreSQL, MySQL, SQLite, and more — or minify them to a single line.

Runs privately in your browser — your input is never uploaded or tracked.

SQL Formatter Online — Beautify and Minify SQL Queries

Turn unreadable, single-line SQL into cleanly indented, reviewable queries with this free online SQL formatter. It understands multiple dialects — PostgreSQL, MySQL, SQLite, SQL Server (T-SQL), and more — so keywords, joins, subqueries, and CTEs are formatted the way your team actually writes them.

Formatting SQL matters: consistent indentation makes code reviews faster, reveals logic errors hiding in dense WHERE clauses, and makes ORM-generated or log-extracted queries readable in seconds. When you need the opposite, the minifier collapses a formatted query to a single compact line for logs or embedding in code.

How to Format a SQL Query Online

  1. Paste your SQL

    Drop in any query — a giant SELECT from your logs, an ORM-generated statement, or a migration script.

  2. Select the dialect

    Choose PostgreSQL, MySQL, SQLite, or another dialect so identifiers and syntax quirks format correctly.

  3. Beautify or minify

    Beautify produces indented, uppercase-keyword output; Minify compresses everything to one line.

  4. Copy the clean query

    Copy the formatted SQL back into your editor, migration file, or documentation.

Features of the SQL Formatter

  • Dialect-aware formatting

    PostgreSQL, MySQL, SQLite, T-SQL and more — each dialect's keywords and operators are handled correctly.

  • Handles complex queries

    CTEs, window functions, nested subqueries, and multi-join statements format cleanly.

  • Beautify and minify

    Expand SQL for readability or compress it for logs and inline strings — both in one tool.

  • Consistent keyword casing

    Keywords are normalized so SELECT, FROM, and JOIN stand out at a glance.

  • Private by default

    Queries often reveal schema details — this formatter runs entirely in your browser, uploading nothing.

Frequently Asked Questions

Which SQL dialects does the formatter support?

It formats standard SQL along with PostgreSQL, MySQL, SQLite, and SQL Server (T-SQL) syntax, covering the dialect-specific keywords and quoting styles of each.

Can it format ORM-generated queries?

Yes — that is one of its best uses. Paste the single-line SQL that Prisma, Hibernate, Django, or ActiveRecord logged, and get a readable, indented version instantly.

Does formatting change what the query does?

No. Formatting only changes whitespace, line breaks, and keyword casing — the semantics of the query are untouched.

Why minify SQL?

Minified SQL is compact for log lines, string literals in code, and URL-embedded queries. It is the same query, just without decorative whitespace.
