Free Online SQL Formatter & Beautifier

Paste your messy SQL and get clean, formatted output with uppercase keywords instantly.

Why Format SQL Queries?

Well-formatted SQL queries are significantly easier to read, debug, and maintain. When working in teams, consistent formatting reduces confusion and helps developers quickly understand complex queries with multiple joins, subqueries, and conditions. Our SQL formatter automatically applies uppercase keywords and clean indentation so your queries look professional every time.

Whether you are writing ad-hoc queries in a database console, building stored procedures, or reviewing SQL in a pull request, a formatter saves you time and mental energy. Instead of manually aligning keywords and indenting clauses, paste your SQL and let the tool do the work.

How It Works

Paste any SQL query into the input box and click "Format SQL." The tool sends your query to the ToolPipe API endpoint POST /api/sql/format with uppercase keyword conversion enabled. The API parses the SQL, identifies keywords, clauses, and expressions, then returns a cleanly indented version. The formatted result appears in the output box, ready to copy.

API Access

Need to format SQL programmatically? Use the API directly:

curl -X POST https://toolpipe.com/api/sql/format \
  -H "Content-Type: application/json" \
  -d '{"sql": "select * from users where id=1", "uppercase_keywords": true}'
