Frequently asked questions

Is this SQL formatter free?

Yes — completely free. No signup, no ads. The formatter runs in your browser so your queries stay private.

Which SQL dialects are supported?

MySQL, PostgreSQL, SQLite, SQL Server (T-SQL), Oracle (PL/SQL), and BigQuery. Pick the right one for accurate keyword handling and reserved-word recognition.

Will it execute or validate my SQL?

No — this tool only formats. It does not run queries, check syntax against a real database, or validate against a schema. Use your database client for execution.

Can I sort or alias keyword case?

Yes. The Keywords dropdown switches between UPPERCASE, lowercase, or preserve original case.

Does it support CTEs and window functions?

Yes — common table expressions (WITH), window functions (OVER), JSON operators, and dialect-specific syntax are all preserved and formatted.

What is SQL Formatter?

An SQL Formatter is a tool that reformats SQL statements with consistent indentation, keyword casing, and line breaks so the query is easier to read and review. Dialect-aware formatters apply the correct reserved-word list and join syntax for each database engine (MySQL, PostgreSQL, SQLite, SQL Server, Oracle, BigQuery).
