SQL Query Formatter

Format SQL queries, and optionally have Claude explain them.

This tool is free and works as long as the token budget lasts. If it helps you, I would be glad about a coffee.

Paste your SQL query

Tips

Just paste the unformatted query — one line or many, it does not matter.
Without AI: instant local formatting (uppercase keywords, indentation, line breaks).
With AI: Claude formats the query and explains what it does.
Works with every SQL dialect (T-SQL, PostgreSQL, MySQL, and so on).
