SQL Formatter (Beautify & Indent SQL Queries)
Format and indent complex SQL queries across PostgreSQL, MySQL, SQL Server, and SQLite dialects.
TL;DR: SQL Formatter transforms messy SQL queries into cleanly indented database statements with capitalized keywords.
How Do I Format and Indent SQL Queries Online?
To format a SQL query, paste your raw SQL statement into a SQL formatter. The parser identifies major SQL clauses (`SELECT`, `FROM`, `WHERE`, `JOIN`, `GROUP BY`, `ORDER BY`), aligns subqueries with indentation, capitalizes reserved SQL keywords, and places column lists on separate lines for readability.
How to Use the SQL Formatter
Our SQL Formatter is engineered for rapid developer workflow, high-performance in-browser execution, and complete code privacy.
- Paste your raw, unformatted, or multi-join SQL query into the editor.
- Select your SQL dialect (Standard SQL, PostgreSQL, MySQL, SQL Server / T-SQL, Oracle, SQLite).
- Configure keyword case (UPPERCASE, lowercase, or preserve).
- Click 'Format SQL' to execute query beautification.
- Copy formatted SQL or download as a `.sql` query script.
Key Capabilities & Developer Best Practices
- Fast In-Browser Processing: Zero server latency; code formatting, validation, and transformations execute in real time.
- Complete Data Confidentiality: Work with sensitive API keys, production configs, and database records safely on your local device.
- Standards-Compliant Output: Generates clean, RFC-compliant code ready for production deployment and clean Git diffs.
100% Client-Side Privacy Guarantee
All parsing, formatting, validation, cryptographic hashing, and code transformations occur 100% locally inside your web browser. Your source code, database queries, and private payloads are never uploaded to any remote server.
Frequently Asked Questions
- A SQL formatter is a database developer tool that formats unformatted or multi-line SQL queries with standardized indentation, uppercase keywords, and clean clause alignment.
- The formatter supports Standard ANSI SQL, PostgreSQL, MySQL, Microsoft SQL Server (T-SQL), Oracle PL/SQL, SQLite, MariaDB, and Snowflake.
- Common Table Expressions (CTEs) and nested subqueries are indented hierarchically with aligned parentheses to make multi-level queries easy to follow.
- Yes. You can automatically capitalize reserved keywords (e.g. `SELECT`, `FROM`, `INNER JOIN`, `WHERE`) to adhere to standard database engineering conventions.
- No. Formatting changes only whitespace and capitalization; the underlying relational algebra, index utilization, and query plan remain identical.
- No. 100% of query formatting executes client-side inside your browser, ensuring absolute security for sensitive database queries.
- Yes. `CASE WHEN ... THEN ... ELSE ... END` statements and `OVER (PARTITION BY ... ORDER BY ...)` clauses are formatted on dedicated indented lines.
- All inline comments and multi-line documentation blocks are preserved in their exact logical positions.
