SQL Formatter & Beautifier Online
Clean up unformatted, single-line, or messy SQL queries into readable, professionally formatted database statements. Standardize keywords to uppercase or lowercase, align major clauses like SELECT, FROM, WHERE, and JOIN on separate lines, and format without uploading data.
- Standardize SQL keywords to uppercase or lowercase
- Format SELECT, FROM, WHERE, JOIN and GROUP BY on separate lines
- Preserve string literals, comments and column identifiers
Format complex SQL queries with clean alignment
Paste your SQL query into the input field, choose uppercase or lowercase keyword casing, and select your preferred indentation width. The formatter restructures the statement, putting major clauses on distinct lines with consistent hierarchical indentation.
Keyword standardization across dialects
The formatter recognizes standard ANSI SQL commands as well as dialect-specific keywords from MySQL, PostgreSQL, SQLite, BigQuery, and SQL Server. Key terms such as SELECT, FROM, WHERE, JOIN, GROUP BY, and ORDER BY are adjusted to your selected case preference.
Protecting string literals and comments
String values enclosed in single or double quotes and numeric literals are tokenized and protected prior to formatting. This guarantees that table data, text filters, and embedded comments remain unmodified.
Database query security and offline execution
Formatting database queries in an online tool can pose security risks if queries contain confidential table schemas or customer data. KKSuite executes all formatting entirely client-side, ensuring no query text is transmitted over the internet.
