Keep every query in your project laid out the same way

Teams rarely agree on how SQL should look, and pasting queries between editors, tickets and code reviews makes it worse. The SQL Formatter applies one consistent layout to whatever you give it: major clauses on their own lines, columns listed one per line, and joins and conditions indented beneath them. Uniform formatting makes diffs shorter and mistakes easier to spot.

Formatting step by step

Paste your query into the SQL Query field, or use the Sample button to load an example with two joins.
Choose your database from the Dialect list. Options are Standard SQL, MySQL, PostgreSQL, T-SQL (SQL Server) and PL/SQL (Oracle).
Click Beautify & Format SQL.
Check the Formatted Query, then press Copy or Download to save it as formatted.sql.

The page also shows the character counts before and after, plus the line count. The Structure Analysis section notes whether the query passes a basic check, names the table after the first FROM and counts JOINs.

Realistic ways to use it

Cleaning up a query before pasting it into a pull request so reviewers can follow it.
Standardizing snippets for a wiki or runbook so every example looks alike.
Making a dense report query readable before adding a new column.
Converting a single-line query from an application log into something you can edit.

Behavior and caveats

Formatting is done by the sql-formatter library, which the page fetches from a public CDN. When it is unavailable, a much simpler fallback places line breaks before major keywords. The dialect setting changes how identifiers and functions are parsed, so use MySQL for backtick-quoted names and T-SQL for square-bracket names. Indentation is fixed by the library, and keywords keep whatever capitalization you entered. The page shows Indentation and Uppercase Keywords controls, but in the current version they do not change the layout, so do not rely on them to enforce a style. Stored procedures with unusual vendor syntax may not lay out perfectly. If the result looks wrong, try a different dialect. The basic validation does not replace running the query on a real database. Processing is in your browser.

Frequently Asked Questions

Do the Indentation and Uppercase options change the output?

In the current version they do not. The layout uses the formatting library's default indentation, and keywords stay in the capitalization you typed. To get uppercase keywords, type them that way before formatting.

Which dialect should I choose?

Match your database: MySQL for backtick-quoted names, PostgreSQL for its operators and casts, T-SQL for SQL Server and bracketed names, PL/SQL for Oracle. If unsure, Standard SQL works for most simple SELECT statements.

Can it format more than one statement at a time?

Yes. Paste several statements separated by semicolons and the formatter lays each one out in turn. The Structure Analysis panel, however, looks only at the first FROM it finds and counts JOINs across the whole text.

Is formatted SQL faster to run?

No. Whitespace has no effect on how a database executes a query. Formatting only improves readability for people. If you need smaller text instead, a minifier removes comments and extra spaces from the statement.

Does it save my query anywhere?

The formatting script runs in your browser, and you take the result away by copying it or using Download, which saves formatted.sql to your device. No account or sign-in is needed to use the tool.
