How to format SQL
Paste compact or messy SQL and make common clauses easier to read without sending the query anywhere.
Readable SQL
The formatter normalizes whitespace, uppercases common keywords, and places major clauses on their own lines.
Format or minify
- Use format mode when reading or sharing a query.
- Use minify mode when you only need normalized single-line SQL.
- Review important queries before running them in production.
Scope
This is a lightweight formatter for common SQL. It is not a full database-specific parser.
Local SQL formatting
SQL text stays in your browser and is never sent to the ProntoUso server.
