Which SQL dialects are supported?

Standard SQL, PostgreSQL, MySQL, MariaDB, SQLite, SQL Server (T-SQL), Oracle PL/SQL, BigQuery, Snowflake, Redshift, Spark, Hive, Trino, DB2, DuckDB and ClickHouse. Pick yours so quoting and keywords are understood.

Does it validate my SQL?

It parses the query to format it, so serious syntax problems such as an unclosed bracket are reported with their line and column. It is not a full validator — it can't know your tables or columns.

Is my query uploaded anywhere?

No, formatting happens entirely in your browser.

Can I choose indentation style, like tabs vs spaces?

Yes: 2 spaces, 4 spaces or tabs.

Does it uppercase SQL keywords automatically?

By default, but you can choose UPPER, lower or As typed.

Can it format complex queries with subqueries and joins?

Yes, the formatter handles nested subqueries and multi-table joins, indenting each clause for readability.

What happens if my SQL has a syntax error?

Formatting stops, the status bar shows the line and column, and the editor underlines the spot. Minify still works on any text.

Are my comments kept?

Yes. Line comments (--) and block comments (/* */) are preserved when formatting. Minify removes them, but never touches string literals or quoted identifiers.
