What SQL dialects are supported?

The formatter handles standard SQL syntax that is common across MySQL, PostgreSQL, SQLite, SQL Server, and Oracle. Keywords are automatically uppercased and indentation is applied to all standard clauses.

Does the formatter change the meaning of my query?

No. The formatter only changes whitespace and capitalization of SQL keywords. The logical meaning and execution of your query remains identical. Your table names, column names, and values are preserved as-is.

Can I minify SQL queries?

Yes. Use the Minify button to compress your SQL query into a single line, removing unnecessary whitespace. This is useful for embedding queries in code or reducing payload size.

Does the formatter handle subqueries and CTEs?

Yes. The formatter properly indents nested subqueries, Common Table Expressions (WITH clauses), JOINs, CASE statements, and UNION queries. Each nesting level gets appropriate indentation for readability.

Why should SQL keywords be uppercase?

Uppercasing keywords (SELECT, FROM, WHERE, JOIN) is a widely adopted convention that makes SQL more readable by visually separating SQL syntax from table/column names. It's a style preference, not a requirement — SQL is case-insensitive for keywords.

Can I format stored procedures or CREATE TABLE statements?

Yes. The formatter supports DDL statements (CREATE TABLE, ALTER TABLE, CREATE INDEX), DML (SELECT, INSERT, UPDATE, DELETE), and procedural SQL. All standard clause types are properly formatted.

How to Use the SQL Formatter

Paste your SQL query into the input panel and the formatted output appears instantly on the right. The formatter automatically adds line breaks before major clauses (SELECT, FROM, WHERE, JOIN, ORDER BY, etc.), applies consistent indentation, and optionally uppercases SQL keywords. Use the "Format" button to apply formatting to the input directly, or "Minify" to compress the query into a single line. Adjust indentation between 2 and 4 spaces. Click "Sample" to load a complex query demonstrating all formatting features.

Why Format SQL Queries?

Properly formatted SQL is dramatically easier to read, debug, and maintain. A 200-character single-line query becomes a structured document where you can quickly identify the columns being selected, the tables being joined, the filter conditions, and the sorting order. Teams that enforce SQL formatting standards have fewer bugs in their queries because logical errors become visible when each clause is on its own line. Formatted SQL also makes code reviews more efficient and helps onboard new team members who need to understand existing queries.

Common Use Cases

Clean up queries from ORM-generated SQL logs. Format stored procedures and views before committing to version control. Beautify queries pasted from database admin tools. Format JSON query results with our JSON Formatter, or use the Regex Tester to extract patterns from SQL output. Prepare SQL examples for documentation and technical blog posts. Minify queries for embedding in application code. All formatting happens in your browser — your SQL queries are never sent to any server, making this tool safe for production queries containing sensitive table names or business logic.
