Format, indent, and uppercase SQL queries with clause indentation, CTE support, and zero database connections.
.sql file.The Todoal SQL Formatter is a browser-native database query beautifier engineered to format messy, unindented, or single-line SQL queries into clean, readable statements. When inspecting application logs, extracting ORM-generated database queries (such as Prisma, TypeORM, or Hibernate), or debugging complex multi-table joins, unformatted SQL queries are challenging to analyze and optimize.
Our SQL formatting engine supports standard SQL dialects including PostgreSQL, MySQL, SQLite, Oracle, Microsoft SQL Server (T-SQL), and MariaDB. It automatically standardizes major SQL keywords (such as SELECT, FROM, WHERE, LEFT JOIN, GROUP BY, and ORDER BY) to uppercase, aligns clause indentation, and separates complex subqueries.
Standardizes clause keywords to uppercase, aligns SELECT columns vertically, and places JOIN, WHERE, and HAVING conditions on dedicated indented lines.
Maintains clear visual nesting across Common Table Expressions (WITH clauses), subqueries, UNION statements, and complex conditional CASE/WHEN expressions.
Download formatted queries as clean .sql files or copy beautified queries to your clipboard with keyboard shortcuts (Ctrl+Enter).
All SQL formatting executes locally in your browser memory. Your proprietary database schemas, table names, sensitive query parameters, and business logic are never uploaded.
Database query optimization is closely tied to overall backend architecture. Format JSON responses from your database using our JSON Formatter, validate JSON schemas with the JSON Validator, convert Unix epoch timestamps from your query results using the Unix Timestamp Converter or Timestamp Converter, and generate unique primary keys with the UUID Generator.
For API and security workflows, decode authentication headers with the JWT Decoder, test regex search patterns with the Regex Tester, format XML feeds with the XML Formatter, and format scripts with the JavaScript Formatter. Explore all utilities in the Developer Tools Suite.
.sql file.Standardizes reserved keywords to uppercase across PostgreSQL, MySQL, SQLite, T-SQL, MariaDB, and Oracle while preserving table and column casing.
Places complex INNER, LEFT, RIGHT, and FULL OUTER joins onto dedicated indented lines with aligned ON conditions for effortless query inspection.
When analyzing slow query logs, reviewing execution plans (EXPLAIN ANALYZE), or auditing complex ORM queries, unformatted single-line SQL makes it nearly impossible to identify missing indexes, unintended cartesian products (CROSS JOINs), or redundant subselects. Formatting queries into clean, indented clauses allows database administrators and backend developers to diagnose performance bottlenecks and optimize query execution plans rapidly.
Messy, single-line SQL queries extracted from ORM frameworks or application logs hinder code reviews and database tuning. The Todoal SQL Formatter standardizes keywords to uppercase, aligns SELECT columns, and structures complex JOIN and WHERE clauses onto separate indented lines, making query maintenance seamless.
Complex SQL statements involving multi-table joins, subqueries, and aggregation clauses are difficult to optimize when compressed onto a single line. The Todoal SQL Formatter standardizes keywords to uppercase, indents nested conditions, and structures queries cleanly for PostgreSQL, MySQL, SQLite, and Oracle databases.
Whether formatting PostgreSQL JSONB queries, MySQL window functions, SQLite schema migrations, or SQL Server stored procedures, Todoal organizes statements with clean keyword alignment, separated predicates, and indented subqueries for effortless database administration.
