Free SQL Formatter that works offline
Make compact SQL easier to read by placing major clauses and comma-separated items on separate lines. Quoted string literals are protected while general whitespace is normalized.
What this sql formatter does
SQL formatting improves review and debugging but does not change query meaning intentionally. Because database dialects have many extensions, this lightweight formatter focuses on common clauses instead of pretending to be a complete parser for every engine.
How to use the SQL Formatter
- Enter or paste a SQL statement using common clauses into the tool.
- Adjust the available options so they match the format and result you need.
- Choose Format SQL and review a whitespace-normalized, line-broken query before using it.
- Copy or download the result, then clear the page if the input was sensitive.
Common uses
- Reading copied queries and logs
- Preparing SQL snippets for documentation
- Reviewing generated SELECT statements
- Normalizing common clauses before comparison
Private processing and offline access
This tool does not submit your input to a conversion server. Processing takes place inside the browser using local JavaScript and standard Web APIs. After the PWA has been installed or cached, the page and its core features remain available without an internet connection. Closing or clearing the page removes unsaved input; the tool does not create an account or cloud history.
Tips for accurate results
- Always test formatted queries in a safe environment.
- Review stored procedures and vendor-specific syntax carefully.
- Formatting does not validate table names, permissions or SQL semantics.
