SQL Formatter and Beautifier

Reading dense one-line SQL is one of the least-fun parts of working with databases. A long join chain crammed onto a single line, a CTE with no indentation, an UPDATE buried in a WHERE clause: any of these can hide bugs that a well-formatted version makes obvious. This formatter takes any SQL you paste in and rewrites it into multi-line, indented form using the popular sql-formatter library, with dialect-aware keyword casing and clause alignment. It supports standard SQL plus the most common dialects: PostgreSQL, MySQL, MariaDB, SQLite, BigQuery, Snowflake, Redshift, and N1QL. The conversion runs entirely in your browser, so you can paste production queries without any of the text leaving your machine. The output is the same SQL semantically, just easier to read, and you can copy it back into your migration file, your worksheet, or wherever you need it.
