Full Dialect Specialization
Tailored formatting for MySQL backticks and comments (#), PostgreSQL dollar strings ($$...$$) and typecasts (::jsonb), plus SQLite autoincrement schemas.
Zero Server Data Retention
Never send confidential production queries, table definitions, or credentials to third-party APIs. Every parsing token is processed locally in your web browser.
Minify for High Throughput
Strip comments, unnecessary spaces, and compress complex queries to single-line strings ready for embedding in application code, microservices, and serverless edge functions.
Frequently Asked Questions & SQL Formatting Best Practices
Why should SQL queries be formatted consistently?
Clean indentation makes complex JOIN hierarchies, nested subqueries, and window functions immediately readable in Git pull requests, facilitating faster debugging and performance tuning.
What is the difference between Trailing and Leading commas?
Trailing commas place the comma at the end of each column line (col1,). Leading commas position the comma at the start of the next line (, col2), preferred by some teams for cleaner git line diffs.
Is my database schema or query text stored anywhere?
No. All tokenizer loops, whitespace transformations, and syntax calculations run strictly within your local browser runtime. No analytics or server requests ever occur.
Can I use this tool for formatting DDL statements?
Yes! DDL statements such as CREATE TABLE, ALTER TABLE, and index declarations are properly indented along with column definitions and constraints.
