SQL Query Formatter
Paste a cramped, one-line SQL query and get back properly indented, readable SQL with consistent keyword capitalization. Debugging queries written by other people just became survivable.
How to use the SQL Formatter
- Paste your SQL statement into the input area.
- Press format to beautify the query.
- Review the indented output with keywords in uppercase.
- Copy the readable version for review, documentation, or your editor.
When the SQL Formatter is useful
- Formatting queries extracted from logs that arrived as a single line.
- Preparing SQL for code review where readability changes everything.
- Understanding a complex inherited query before modifying it.
- Standardizing keyword casing across a team's SQL style guide.
How the SQL Formatter works
The formatter parses SQL structure, clauses, joins, subqueries, and condition lists, and applies layered indentation that mirrors the query's logical depth. Keywords like SELECT, FROM, and WHERE are uppercased per common convention while preserving your identifiers and string literals exactly. Formatting runs entirely in your browser, an important property when the query came from an internal system and may contain table or column names you would rather not share.
Limits to keep in mind
Formatting changes whitespace and keyword case only; dialect-specific syntax may not align perfectly if it mixes clauses in unusual ways.
Frequently asked questions
Which SQL dialects are supported?
Standard SQL structure common to major dialects formats well; exotic vendor syntax may fall back to lighter indentation.
Does it change my query logic?
No. Only whitespace, line breaks, and keyword capitalization are adjusted.
Is my query sent to a server?
No. Formatting happens locally, which keeps internal schema details private.
