Free SQL Formatter Online
Pretty-print SQL in the browser: keyword casing, line breaks before clauses, and indentation. This is a formatter, not a database runner.
About SQL Formatter
Format SQL online with this free SQL formatter that adds readable line breaks, indentation, and consistent keyword casing. Paste a long SELECT, JOIN, INSERT, UPDATE, or DELETE statement and get a query that is easy to review in a pull request or paste into a migration. It works with MySQL, PostgreSQL, SQL Server, and SQLite style syntax so you can tidy queries from logs, ORMs, and admin tools.
A SQL formatter is useful when a query arrives as one line from a profiler, when you need to share SQL in a ticket, or when you want clauses stacked so JOIN and WHERE are obvious. Database developers, analysts, and backend engineers format SQL before they debug slow queries or document a report. Readable SQL also reduces mistakes when you edit a condition or add a column.
The formatter focuses on layout, not execution. It does not connect to a database and does not run your statement. That makes it safe for production SQL that contains real table names. If the text cannot be parsed as SQL, you get feedback instead of silently broken output. Copy the formatted query and paste it into your editor, notebook, or review comment.
Your query is formatted in the browser and never sent to a server. Schema names, filters, and comments stay private. Use this free online SQL formatter and SQL pretty printer whenever you need clean, indented SQL without installing a desktop client.
