What the SQL Formatter does
Paste a cramped, one-line query and get back clean, indented SQL you can actually read. This tool uppercases the main keywords (SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY and more), drops each clause onto its own line, and breaks long comma-separated column lists into a tidy indented list. It is handy when you copy a query out of application logs, an ORM, or a chat message and need to make sense of the structure before you debug or share it.
It helps developers, data analysts, students, and anyone reviewing a pull request who would rather scan a formatted statement than squint at a wall of text.
How to use it
- Paste or type your SQL into the input box (something like
select id,name from users where age>18). - Click Format SQL.
- Read the cleaned-up query in the output box: keywords are capitalized, clauses sit on separate lines, and columns are indented.
- Press Copy to grab the formatted result for your editor, ticket, or doc.
There are no settings to fiddle with. The formatting applies the moment you run it.
Why format SQL here
It is quick: the result appears instantly with one click, no waiting on a server round trip. It is private, because the whole thing runs inside your browser and your query never gets uploaded anywhere. And it is free with no sign-up and no file limits, on phone, tablet, or laptop alike.
Tip: this formatter focuses on readability rather than rewriting your logic, so the query stays exactly the same, just easier on the eyes. For very dialect-specific syntax (window functions, CTEs, vendor extensions), double-check the spacing before running it in production.
Frequently asked questions
- How does the SQL formatter clean up my query?
- It collapses extra whitespace, capitalizes the main keywords (SELECT, FROM, WHERE, the JOIN types, GROUP BY, ORDER BY, HAVING, LIMIT and more), puts each clause on its own line, and breaks comma-separated columns onto indented lines so the structure is easy to scan.
- Does the SQL formatter change what my query does?
- No. It only adjusts spacing, line breaks, and keyword casing for readability. The tables, columns, conditions, and logic stay exactly as you typed them, so the query returns the same result.
- Is my SQL sent to a server?
- No. The formatting runs entirely in your browser using JavaScript. Your query is never uploaded, which makes it safe for code that touches internal table or column names.
- Which SQL dialects does it support?
- It works with standard SELECT, INSERT, UPDATE, and DELETE statements across common dialects like MySQL, PostgreSQL, and SQL Server. Very vendor-specific syntax such as complex CTEs or window functions may need a quick manual check afterward.
