Runs locally in your browser
SQL Formatter
Format common SQL queries for code review, debugging, documentation, or compact sharing.
What this SQL Formatter is for
Use this SQL Formatter when you need to clean up a query before debugging, reviewing a pull request, pasting SQL into documentation, or sharing an example with another backend developer.
The formatter runs in your browser. It does not upload queries, table names, comments, or example data to a server.
How to use it
Paste a SQL query, choose a keyword style, then click Format SQL. Use Minify SQL when you need a compact one-line version for logs, scripts, or small examples.
This is a lightweight formatter, not a full SQL parser. It handles common query shapes and protects quoted strings, but you should still run database-specific validation before shipping a query.
