Developer
Free SQL Formatter & Beautifier
Format and beautify messy SQL queries instantly with proper indentation.
About this tool
Writing SQL queries can easily become messy, especially when dealing with complex joins, nested subqueries, and long lists of selected columns. A single-line SQL query is almost impossible for a developer to read and debug efficiently.
This SQL Formatter takes raw, unformatted SQL strings and converts them into readable, structured code. It automatically uppercases SQL keywords (like SELECT, FROM, WHERE), adds appropriate line breaks before major clauses, and indents logical operators (like AND, OR) and comma-separated lists to make the query structure visually clear.
This tool runs entirely in your browser using a custom formatting engine. No SQL data, schema information, or query logic is ever sent to a server, ensuring complete data privacy.
How to use
Step 1: Paste your raw SQL query into the input box on the left.
Step 2: Click Format SQL to instantly beautify the code.
Step 3: The formatter will uppercase keywords and apply indentation.
Step 4: To compress the query into a single line, use the Minify button.
Step 5: Click Copy to copy the resulting SQL to your clipboard.
Frequently Asked Questions
This formatter uses a generic ruleset that works well with standard SQL, MySQL, PostgreSQL, SQLite, and SQL Server. It handles standard keywords like SELECT, JOIN, WHERE, GROUP BY, etc.
No. This tool only formats the text string of the query. It does not connect to any database or validate if the tables/columns actually exist.
The Minify button does the opposite of formatting: it removes all unnecessary whitespace and line breaks, compressing the query into a single line. This can be useful when you need to paste a query into a single-line text field or string variable in code.
