SQL Formatter and Beautifier
Description
Format, beautify, and indent SQL queries for readability — customizable indentation, uppercase keywords, and line breaks.
About SQL Formatter and Beautifier
The SQL Formatter beautifies and indents SQL queries for readability, in your browser. It normalizes keyword casing, aligns clauses, and breaks long statements across lines so a dense one-liner becomes a query you can actually review. It supports standard SQL syntax and common dialects, making it handy for cleaning up generated queries, code reviews, and documentation.
How to use
- Paste your SQL — a single line or a messy multi-statement script — into the input.
- Pick the dialect and indentation that match your codebase.
- The formatted query appears on the right, ready to copy.
- Optionally uppercase keywords for a consistent house style.
Frequently asked questions
Does formatting change what my query does?
No. Formatting only adds whitespace, line breaks, and keyword casing. The query's logic and results are unchanged — it's purely cosmetic.
Which SQL dialects are supported?
Standard SQL plus common dialects. Vendor-specific extensions usually format fine, but very unusual syntax may not align perfectly — the statement still runs identically.
Will it run or validate my query against a database?
No. It only formats text. It does not connect to any database, execute queries, or check that tables and columns exist.
Is my SQL uploaded anywhere?
No. Formatting happens entirely in your browser, so queries that reference real schema names stay private.
