SQL Formatter
Format SQL queries with proper indentation. Free, no signup.
How It Works
Paste your SQL query and click Format. The tool adds line breaks and indentation around major SQL keywords (SELECT, FROM, WHERE, JOIN, etc.) for better readability.
What the Formatter Does
- Collapses runs of spaces, tabs and blank lines into clean, consistent spacing.
- Puts each major clause on its own line so the query structure is easy to scan.
- Uppercases recognized SQL keywords for a standard, readable style.
- Indents conditions (AND, OR, ON) and CASE branches under the clause they belong to.
- Leaves your columns, tables and values untouched, then offers one-click Copy.
Why Format SQL?
A one-line query pasted from a log or an ORM is hard to read and easy to misread. Formatting it into clear clauses makes it faster to review, easier to debug, and consistent when you commit it to version control or share it with teammates. Because everything runs locally, you can safely tidy up queries that reference internal tables without sending them anywhere.
Frequently Asked Questions
How do I format a SQL query?
Paste your SQL into the box and click Format. The tool collapses messy whitespace and puts each major clause, such as SELECT, FROM, WHERE and JOIN, on its own line with consistent two-space indentation, then shows the result ready to copy.
Does the formatter change the meaning of my query?
No. It only adds line breaks and indentation and uppercases recognized keywords for readability. The clauses, columns, table names and values are left exactly as you wrote them, so the query still runs the same way.
Which SQL dialects does it work with?
It formats standard SQL keywords, so it works with common dialects like MySQL, PostgreSQL, SQL Server, SQLite and Oracle for typical SELECT, INSERT, UPDATE, DELETE and DDL statements. It formats by keyword rather than parsing a specific dialect, so it does not rewrite vendor-specific syntax.
Does it check my SQL for errors?
No. This is a formatter, not a validator or linter. It reformats whatever you paste for readability but does not run the query or check it for syntax mistakes.
Is the SQL formatter free and private?
Yes. It is completely free with no signup, and your query never leaves your browser. All formatting happens on your device in JavaScript, so nothing is uploaded to a server.
