TOOLS · SQL FORMATTER
Turn a wall of SQL into something readable.
Paste in a query written on one line (or copy-pasted from somewhere with inconsistent spacing) and get it broken into clean, indented clauses — SELECT columns, JOINs, WHERE conditions, and more, each on their own line.
Why Format SQL?
SQL that's been copy-pasted from a log, an ORM's debug output, or written in a hurry often ends up as one long line with inconsistent spacing. Formatting breaks it into its natural clauses — SELECT, FROM, JOIN, WHERE, GROUP BY — each on their own line with consistent indentation, which makes a query's structure obvious at a glance instead of something you have to mentally parse.
How This Tool Stays Safe
This formatter only ever adds whitespace — it never removes or rewrites a token. That's a provable guarantee: strip all whitespace from the input and strip all whitespace from the output, and they're identical. Nothing about your query's logic or content changes; it's purely a readability transformation.
Common Uses
- Making sense of a query copied from application logs or an ORM's generated SQL.
- Cleaning up a query before including it in a code review, a bug report, or documentation.
- Reformatting a query someone else wrote in a style that's hard to read.
Frequently Asked Questions
Does this validate whether my SQL is correct?
No — this is a formatter, not a SQL parser or validator. It recognizes keywords to decide where to break lines, but it doesn't check whether your query is syntactically valid or would actually run against a database.
Which SQL dialect does it support?
The formatting rules are based on standard SQL keywords common across MySQL, PostgreSQL, SQL Server, and similar systems. Dialect-specific syntax should pass through unchanged, since the formatter only adds spacing around recognized keywords.
Can formatting break my query?
No — since the tool only adds whitespace and never touches the actual tokens, the query means exactly the same thing before and after formatting.
