SQL Query Beautifier
Beautify SQL queries with keyword casing, custom indent width and dialect-aware formatting.
About 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.
If your team already documents a preferred SQL style, configure those toggles once and keep them as the local default. That reduces review noise from mixed lowercase keywords, inconsistent commas and ad-hoc indentation in shared queries.
How SQL Query Beautifier works in practice
- 1Paste the query you want to beautify.
- 2Pick a dialect from the dropdown.
- 3Set keyword casing, indentation and comma placement.
- 4Click "Beautify" and copy the polished query.
- 5Re-open later on the same browser to reuse the saved style preferences.
Jobs this tool is built for
- 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.
- Normalize vendor-exported SQL before checking it into a shared analytics repository.
- Prepare a pull-request-ready statement that matches an existing leading-comma house style.
What you can do here
- Separate casing rules for keywords, functions and identifiers
- Leading or trailing comma style
- Optional single-line output for short queries
- Style preferences saved in your browser
- Same dialect support as the SQL Formatter
- Finer control than the default SQL Formatter for style-guide compliance
Limits and honest caveats
- Beautification changes source presentation only; it does not inspect database schemas, permissions, query plans or result correctness.
- Identifier casing can interact badly with quoted, case-sensitive names — preview changes on a staging copy of the query first.
- localStorage preferences are device- and browser-local; document the agreed settings for teammates on other machines.
Common questions about SQL Query Beautifier
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.
Why prefer leading commas?
Leading commas make it easier to reorder or comment out SELECT columns in diffs because each line owns its separator. Trailing commas remain available if that matches your existing codebase.
Can I share my beautifier settings with the team?
Not automatically. Copy the chosen dialect, casing and comma options into your style guide or editor config so others can match them.
