About SQL Formatter
The SQL Formatter turns cramped, single-line queries into readable SQL: keywords are uppercased and major clauses — SELECT, FROM, WHERE, JOINs, GROUP BY, ORDER BY — each start on their own line with sensible indentation.
It's built for the everyday case: a long query copied from application logs, an ORM's generated SQL, or a teammate's one-liner that needs review. Readable SQL is easier to debug, diff and optimize.
Formatting runs entirely in your browser, so production queries and schema details never leave your machine.
How to Use the SQL Formatter
- Paste your SQL query into the input pane.
- The formatted query appears instantly with uppercase keywords and one clause per line.
- Copy the result back into your code or editor.
Features
- Uppercases SQL keywords automatically
- New line per major clause, indented JOINs and conditions
- Preserves string literals exactly as written
- Handles multiple statements separated by semicolons
Frequently Asked Questions
Which SQL dialects are supported?
The formatter works on standard SQL keywords shared by PostgreSQL, MySQL, SQL Server, SQLite and most other dialects. Dialect-specific syntax passes through unchanged.
Will formatting change what my query does?
No. Only whitespace and keyword casing change; identifiers and string literals are preserved exactly, so the query executes identically.
Is the SQL Formatter free?
Yes, the SQL Formatter is completely free with no usage limits. No signup, no account and no installation required.
Is my data safe?
Yes. All processing happens locally in your browser using JavaScript — nothing you type is uploaded or stored on our servers.
