Free Online SQL Formatter

Beautify and format SQL queries instantly in your browser. Support for MySQL, PostgreSQL, SQL Server, Oracle, SQLite, MariaDB, and BigQuery, with custom keyword casing and indentation. No sign-up, nothing stored.

What is a SQL Formatter?

A SQL formatter takes a raw, unformatted, or minified SQL query and rewrites it with consistent indentation, line breaks, and keyword casing. The result is a readable, standardized query that is far easier to scan, review, and debug than a single dense line of text.

This tool formats SQL for eight popular dialects and lets you choose how keywords are cased and how clauses are indented. Everything runs client-side, so even sensitive production queries never leave your browser.

Key Features

Instant Beautifier

Messy, one-line, or minified SQL is reindented and aligned as you type — no button to press.

8 SQL Dialects

Format for Standard SQL, MySQL, PostgreSQL, MariaDB, SQLite, SQL Server, Oracle PL/SQL, or BigQuery.

Keyword Casing

Force keywords to UPPERCASE, lowercase, or preserve them exactly as you wrote them.

Custom Indentation

Choose 2 spaces, 4 spaces, or tabs to match your team's style guide and editor settings.

Copy & Download

Copy the formatted query to your clipboard or download it as a ready-to-use .sql file.

100% Client-Side

Your queries are formatted entirely in your browser. Nothing is uploaded, logged, or stored.

How to Format SQL

1

Paste your SQL

Drop a query into the input panel on the left — minified, single-line, or already partly formatted.

2

Pick your dialect

Select the database you target so the formatter understands dialect-specific syntax and functions.

3

Set casing and indent

Choose UPPERCASE, lowercase, or preserve for keywords, and 2 spaces, 4 spaces, or tabs for indentation.

4

Copy or download

The formatted query updates live on the right — copy it or save it as a .sql file with one click.

Common Use Cases

  • Code review: Normalize SQL pulled from logs or pull requests so reviewers can read the query structure at a glance.
  • Debugging queries: Expand a dense one-liner into aligned clauses to spot a misplaced join, filter, or grouping fast.
  • Documentation: Produce clean, consistently indented snippets to paste into wikis, runbooks, and README files.
  • ORM-generated SQL: Beautify the unreadable SQL emitted by ORMs and query builders to understand what actually runs.
  • Team style consistency: Apply one casing and indentation standard across every query so checked-in SQL stays uniform.

Frequently Asked Questions

Is this SQL formatter free to use?

Yes. The SQL Formatter is completely free with no sign-up, no limits, and no ads interrupting your work. Format as many queries as you like.

Is my SQL sent to a server?

No. Formatting happens entirely in your browser using client-side JavaScript. Your queries never leave your device and nothing is stored or logged.

Which SQL dialects are supported?

You can format Standard SQL, MySQL, PostgreSQL, MariaDB, SQLite, SQL Server (T-SQL), Oracle PL/SQL, and BigQuery. Pick the dialect that matches your database for the most accurate result.

Can I control keyword casing and indentation?

Yes. Set keywords to UPPERCASE, lowercase, or preserve their original case, and choose between 2 spaces, 4 spaces, or tab indentation to match your style guide.

What happens if my SQL has a syntax error?

If the query cannot be parsed, the input is highlighted and an inline error message explains the problem. Fix the syntax and the formatted output updates instantly.

Does formatting change what my query does?

No. The formatter only adjusts whitespace, line breaks, indentation, and keyword casing. The logic and results of your query stay exactly the same.
