SQL Formatter and Beautifier
Paste any SQL query and instantly beautify it with consistent indentation and uppercase keywords, or minify it to a compact single line. Select from six SQL dialects for dialect-aware formatting. The sql-formatter library runs entirely in your browser — no SQL is transmitted anywhere.
Frequently Asked Questions
- What SQL dialects are supported?
- The formatter supports Standard SQL, MySQL, PostgreSQL, SQLite, T-SQL (SQL Server), and BigQuery. Select your dialect from the dropdown for best results.
- Does the formatter validate SQL?
- The tool performs basic structural formatting. It will show an error if the SQL is so malformed it cannot be parsed. It does not validate SQL against a live database schema.
- Is my SQL data safe?
- Yes. All formatting happens in your browser using the sql-formatter JavaScript library. No SQL is ever sent to any server.
- Can I format stored procedures or complex queries?
- Yes. The formatter handles complex queries including subqueries, CTEs (WITH clauses), JOINs, window functions, and most standard SQL constructs.
- What does minify do?
- Minify collapses the SQL query to a single line by removing extra whitespace and newlines. This is useful for embedding SQL in strings, config files, or URLs.
