Free SQL Formatter
Turn one-line SQL monsters into readable queries. This free formatter uppercases keywords, breaks major clauses onto their own lines, and indents subqueries and conditions — so you can actually follow the logic before you run it.
Formatted SQL
How to Use the SQL Formatter
- Paste your SQL query into the input box.
- Choose whether keywords should be uppercased.
- Click Format SQL — the query is restructured instantly.
- Copy or download the formatted query.
Features
The formatter recognizes the full clause vocabulary — SELECT, FROM, WHERE, GROUP BY, ORDER BY, HAVING, LIMIT, all JOIN types, UNION, INSERT, UPDATE, DELETE — and places each on its own line with consistent indentation. AND/OR conditions break onto separate lines, subqueries indent one level deeper, and string literals are protected so quoted text is never treated as keywords.
Benefits & Use Cases
Developers reformat ORM-generated or logged queries before debugging slow statements; analysts make inherited reporting SQL reviewable; DBAs tidy queries before sharing them in tickets. Readable SQL gets debugged in minutes instead of hours — and nothing sensitive leaves the browser.
Tips
Formatting does not change query semantics, so it is safe to run on any SELECT before EXPLAIN-ing it. For very long IN lists, consider whether the query itself needs restructuring rather than just reformatting.
Frequently Asked Questions
What does a SQL formatter do?
It rewrites SQL with consistent capitalization, line breaks before major clauses, and indentation for subqueries and conditions — making the query’s structure visible without changing what it returns.
Will formatting change my query results?
No. Only whitespace and keyword casing change; the logic, filters, and joins are untouched, so results are identical.
Which SQL dialects are supported?
The formatter targets standard SQL keywords shared by MySQL, PostgreSQL, SQL Server, SQLite, and others. Dialect-specific functions pass through as-is.
Does it work with stored procedures?
Simple procedure bodies format acceptably, but complex procedural SQL with control flow is beyond a lightweight formatter — review the output before relying on it.
Is my SQL uploaded anywhere?
No. Formatting runs entirely in your browser — your queries and any data in them never leave your device.
