Pretty-prints and indents SQL for readability across many dialects. Runs entirely in your browser — your query is never uploaded.

Quick answer

A SQL formatter pretty-prints a query so it's readable: it puts clauses on their own lines, indents consistently, and standardizes keyword casing. Paste your SQL, choose the dialect (Standard SQL, MySQL, PostgreSQL, SQL Server, and more), and the formatted result appears instantly, ready to copy. It runs entirely in your browser, so your query is never uploaded.

Formula & method

The query is parsed into its clauses (SELECT, FROM, JOIN, WHERE, GROUP BY, and so on) and re-printed with each major clause on a new line, nested expressions indented by your chosen width, and keywords cased to upper, lower, or left as written. You can pick the SQL dialect so dialect-specific syntax is handled correctly.

Examples

Example 1: One-line query
Input
select * from users where id=1
Result
SELECT *\nFROM users\nWHERE id = 1
Why
Each clause goes on its own line with uppercased keywords.
Example 2: Joins and grouping
Input
A query with JOIN and GROUP BY
Result
Indented, clause-per-line
Why
Joins and grouping become easy to scan.
Example 3: Choose the dialect
Input
Dialect = PostgreSQL
Result
Postgres-aware formatting
Why
Dialect-specific syntax is preserved correctly.

When to use this tool

  • Cleaning up a long or auto-generated query before reading or committing it.
  • Standardizing SQL style across a team or a code review.
  • Making a one-line query readable for debugging.

Common mistakes

  • Formatting with the wrong dialect, which can mishandle dialect-specific syntax.
  • Expecting the formatter to fix logic or syntax errors — it only reformats valid SQL layout.
  • Pasting multiple statements and forgetting they're each formatted in turn.

Frequently asked questions

Which SQL dialects are supported?

Standard SQL plus MySQL, MariaDB, PostgreSQL, SQLite, SQL Server (T-SQL), BigQuery, and Snowflake, so dialect-specific syntax is formatted correctly.

Can I control the keyword case?

Yes. Choose UPPERCASE, lowercase, or preserve the original casing of SQL keywords.

Is my query uploaded?

No. Formatting happens entirely in your browser; the SQL never leaves your device.

Does it validate my SQL?

It formats the layout but doesn't check that the query is logically correct or will run. It reports an error only if it can't parse the structure.

Can it minify SQL too?

It focuses on readable formatting. For a compact form, set a small indent; the goal here is clarity rather than minification.

Does it handle comments?

Yes, SQL comments are preserved in the formatted output.
