SQL Query Beautifier
Beautify SQL queries with keyword casing, custom indent width and dialect-aware formatting.
What is the SQL Query Beautifier?
The SQL Query Beautifier is the SQL Formatter with more granular style controls: separate casing rules for keywords, functions and identifiers, leading or trailing comma placement, and single-line output for short queries.
It is built for teams that enforce a strict internal SQL style guide. Separating token casing and comma placement helps align generated, legacy and hand-written SQL without manually touching every clause.
Preferences persist in your browser via localStorage. Beautification focuses on presentation and does not connect to a database, evaluate query plans or guarantee semantic correctness.

- 2Pick a dialect from the dropdown.

When to use the SQL Query Beautifier
- Apply a team convention such as uppercase keywords and leading commas before review.
- Reformat SQL generated by an ORM so a slow query is easier to analyze.
- Standardize mixed styles while migrating a collection of reports or saved queries.
- Produce compact one-line output for a short statement embedded in configuration.

- Beautification changes source presentation only; it does not inspect database schemas, permissions, query plans or result correctness.
Frequently asked questions
How is this different from the SQL Formatter?
The Beautifier exposes more style toggles (per-token casing, comma style). The Formatter is the fast default for casual use.
Does it validate the query syntax?
It flags obvious parse errors but is not a full linter.
Where are my style preferences stored?
They are kept in this browser's localStorage. They do not follow you to another browser or device and may disappear if site data is cleared.
Will changing identifier case break my query?
Some databases treat quoted identifiers as case-sensitive. Review identifier-casing changes carefully when the schema uses quoted or mixed-case names.
