What is the SQL Formatter?

A SQL formatter turns dense, single-line database queries into readable, indented statements. It understands PostgreSQL, MySQL and SQL Server syntax, so keywords, strings and comments are laid out consistently and your WHERE clauses stop looking like alphabet soup.

Readable SQL is easier to review, debug and maintain. Because formatting runs locally, sensitive queries with real credentials or customer data never leave your browser, and the Python/PHP export wraps the formatted query in a ready-to-paste string literal for your code.

How to use the SQL Formatter?
  1. Paste your SQL query into the input box.
  2. Pick a dialect and click Format SQL.
  3. Use Convert to Python/PHP String to embed the query in your code, or copy the result.

Frequently Asked Questions (FAQ)

Can I copy the formatted SQL into Python or PHP code?

Yes. Convert to Python String wraps the formatted query in a triple-quoted Python string, and Convert to PHP String escapes it into a PHP $sql literal ready to paste.

Does the SQL Formatter validate my SQL?

It checks that parentheses are balanced and reports the line of the first mismatch. It does not connect to a database, does not run a full syntax check, and never executes your SQL.

Is the SQL Formatter free?

Yes, free with no signup or limits.

Are my queries uploaded?

No. Formatting happens entirely in your browser.

Which dialects are supported?

PostgreSQL, MySQL and SQL Server (T-SQL).
