How to use the SQL Formatter
Choose formatting options
Select your preferred indentation size and keyword case (uppercase or lowercase). The SQL formatter applies these settings instantly, transforming messy queries into clean, readable, well-structured SQL code.
Copy the formatted output
Copy the beautified SQL query to your clipboard with one click. The SQL formatter produces consistently formatted output that's easier to read, debug, and share with your development team.
How this tool works
The component identifies common SQL keywords and structural separators, then applies indentation and line breaks without executing the query.
- Engine: Client-side token and whitespace formatting rules
- Supported input: common SQL statements
- Output: formatted SQL text
- Input
- select id,name from users where active=1
- Output
- SELECT fields, FROM, and WHERE arranged on readable lines
Limits, edge cases, and troubleshooting
Use it to improve readability before review. Check vendor-specific functions and quoted identifiers after formatting.
- The statement must fit in browser memory.
- The formatter is not a database parser and may not understand every vendor dialect, procedural block, or custom delimiter.
When to use another workflow
Use your database IDE or a dialect-aware parser for linting, query plans, schema validation, and automated repository formatting.
| Option | Best for | Trade-off |
|---|---|---|
