SQL Formatter

SQL beautifier online

Use this online SQL formatter to turn a compact query into a readable SQL statement. The SQL prettifier adds indentation and line breaks so you can review SELECT columns, joins and conditions before sharing your query.

How to use it

Paste your SQL query or select Try example. Choose SQL, PostgreSQL, MySQL, PL/SQL or T-SQL in Dialect to match your source. Select Run tool, review the formatted SQL, then copy or download the result.

Options and example settings

Worked examples

Prettify SQL copied from a log, application or query editor before reviewing it with a colleague. Use the result to follow selected columns and WHERE conditions more easily.

Format a SQL query online: SELECT, WHERE and ORDER BY

Settings: Dialect: sql

Input:

select id,name from users where active=true order by name

Output:

SELECT
  id,
  name
FROM
  users
WHERE
  active = TRUE
ORDER BY
  name

The example output has 9 lines. Compare its order, separators and whitespace with the input before copying the result.

Choose the right tool

Formatting changes presentation, not an execution plan. SQL IN List Builder creates value lists; PostgreSQL Query Plan Viewer reads an EXPLAIN JSON plan. Neither runs a database query.

Limitations and common mistakes

• Choose the dialect matching your database before formatting.
• Review comments, quoted names and dialect-specific expressions in the output.
• Formatting improves readability; it does not validate permissions, schema, execution plans or performance.

Frequently asked questions

Are SQL prettifier, SQL beautifier and SQL formatter the same thing?

For this tool, yes. These names refer to SQL query formatting: making the statement easier to read with spacing, line breaks, indentation and consistent keyword case. SQL pretty print is another common name for the same task.

How does SQL format change the query?

The formatter changes the layout and keyword case. It does not intentionally change query logic, but you should review the output before using it, especially when your database uses dialect-specific syntax.

Can I prettify MySQL, PostgreSQL or SQL Server queries?

Choose mysql for MySQL, postgresql for PostgreSQL, or tsql for SQL Server. The Dialect selector also offers generic SQL and plsql. Supported parsing depends on the selected dialect; unusual syntax may need manual formatting.

Does this query formatter execute or optimize SQL?

No. It formats pasted text in your browser. It does not connect to a database, execute statements, check table names or indexes, or measure query speed. Successful formatting does not prove a query will run.

How can I beautify SQL online?

Paste your SQL query or select Try example. Choose SQL, PostgreSQL, MySQL, PL/SQL or T-SQL in Dialect to match your source. Select Run tool, review the formatted SQL, then copy or download the result.

Where is my input processed?

The bundled tool processes input in your browser. It does not upload tool input to a conversion service. Other site plugins, analytics, advertising and browser extensions may have separate behavior.
