What is SQL Formatter?

Free online SQL formatter to beautify messy or minified SQL queries into clean, readable code with proper indentation and syntax highlighting.

It supports standard ANSI SQL, MySQL, PostgreSQL, SQL Server (T-SQL), and SQLite dialects, so you can pretty print a query for the database you actually use. Customize the indentation size, uppercase the keywords, and format complex statements with subqueries, multiple joins, CTEs, and window functions. You can also minify SQL back into a single line for embedding in code. Useful for reading a query pulled from a log, cleaning up auto-generated SQL, or making a stored procedure easier to debug. All formatting runs client-side, so your queries never leave your browser. No signup required.

How to Use SQL Formatter

1Paste your SQL query into the input editor
2Select your SQL dialect and formatting preferences (indentation size, keyword casing)
3Click 'Format' to beautify the query with proper indentation
4Copy the formatted SQL or compare it side by side with the original

Frequently Asked Questions

The formatter supports standard SQL (ANSI), MySQL, PostgreSQL, Microsoft SQL Server (T-SQL), and SQLite. Each dialect may have specific keywords and syntax variations that are handled correctly during formatting.

Yes. The formatter handles complex SQL including nested subqueries, multiple JOIN types (INNER, LEFT, RIGHT, FULL, CROSS), Common Table Expressions (CTEs), UNION/INTERSECT/EXCEPT, CASE statements, and window functions. Each element is properly indented for readability.

No. The formatter only changes whitespace and letter casing (if you enable keyword uppercasing). It never modifies the logic, table names, column names, or values in your query. The formatted query produces identical results to the original.

Yes. All formatting is done locally in your browser. Your SQL queries, which may contain sensitive table names, column data, or business logic, are never sent to any external server.

Pick the dialect that matches your database so identifier quoting and keywords format correctly: MySQL uses backticks, PostgreSQL and standard SQL use double quotes, and SQL Server uses square brackets. If you are unsure, standard SQL works for most plain SELECT, INSERT, and UPDATE statements.

Yes. Use the minify option to collapse a multi-line query into a single line with normalized spacing, which is convenient when you need to paste the SQL into a string literal in your application code.
