How to use it

Paste your SQL, pick the dialect that matches your database, choose whether keywords should be UPPER case, lower case or left as typed, then press Format (or Cmd/Ctrl+Enter). The query is re-indented with each clause on its own line and columns aligned, ready to copy back into your editor or a code review.

An SQL formatter takes a cramped, one-line or inconsistent query and lays it out with proper indentation, line breaks and keyword casing so it is easy to read and review. Choose your database dialect — MySQL, PostgreSQL, SQL Server, Oracle, SQLite, BigQuery and more — set keywords to upper or lower case, and format. It all runs in your browser, so your queries are never sent anywhere.

Why dialect matters

Different databases add their own keywords and syntax — PostgreSQL, MySQL, SQL Server (T-SQL), Oracle (PL/SQL), BigQuery and Snowflake all differ. Picking the right dialect means the formatter recognises those keywords and lays the query out correctly instead of mangling vendor-specific syntax.
