Question 1

What does this SQL formatter do?

Accepted Answer

It beautifies messy or minified SQL into clean, indented, readable code. Paste your query, pick a dialect, and format, minify or validate it.

Question 2

Is my SQL sent to a server?

Accepted Answer

No. Formatting runs entirely in your browser using the sql-formatter library, so your query never leaves your device and stays completely private.

Question 3

Which SQL dialects are supported?

Accepted Answer

Standard SQL, PostgreSQL, MySQL, MariaDB, SQLite, Oracle PL/SQL, SQL Server (T-SQL), BigQuery, Snowflake and Spark SQL — each with its own keywords and syntax.

Question 4

Can I control keyword casing?

Accepted Answer

Yes. Choose UPPERCASE, lowercase or keep the original casing for SQL keywords like SELECT, FROM and WHERE.
