Frequently Asked Questions

Does this work with complex nested queries?

Yes. The formatter handles subqueries, CTEs (WITH clauses), nested JOINs, and CASE statements with proper indentation at each level.

What dialect should I choose?

Choose the dialect matching your database server. The main difference is dialect-specific functions and keywords (e.g., ISNULL vs COALESCE, LIMIT vs TOP). Generic SQL works fine for most standard queries.

Does it validate my SQL syntax?

This tool formats SQL — it does not execute or validate it. For validation, test your queries against an actual database or use a database-specific linter.

Is my database schema or data safe?

Yes. Only the SQL text you paste is processed, entirely in your browser. Nothing is sent to any server.
