SQL Formatter — Free Online SQL Beautifier in Your Browser

Messy SQL is hard to read, hard to debug, and even harder to maintain. This free online SQL formatter cleans up your queries in one click — capitalizes keywords, indents clauses, and breaks long lines into a readable structure. It runs 100% in your browser, so your SQL never leaves your device.

How to use the free SQL formatter

  • Paste your raw SQL query into the Input box (or load the sample to see it in action).
  • Click Format SQL — keywords are uppercased, clause starters get their own lines, and sub-queries are auto-indented.
  • Copy the formatted result with one button, or clear the boxes and start over.

No limits, no uploads, no account needed. The formatter handles SELECT, INSERT, UPDATE, DELETE, JOINs, CASE expressions, window functions (ROW_NUMBER, RANK, LAG...), and common SQL dialects — all through the same clean pipeline.

Example

Paste this one-liner:

SELECT name, COUNT(*) FROM products GROUP BY name HAVING COUNT(*) > 1

and the formatter turns it into a structured, readable query:

SELECT name,
COUNT(*)
FROM products
GROUP BY name
HAVING COUNT(*) > 1

Keywords are uppercased, clause starters (FROM, WHERE, GROUP BY, ORDER BY, HAVING, LIMIT...) get their own lines, and sub-queries are indented automatically — so even a giant 40-line JOIN is scannable in seconds.
