How SQL Formatter works

  1. Paste your SQL query into the input box — single-line or already partially formatted.
  2. The tool automatically reformats it as you type, breaking clauses and joins onto new lines.
  3. Review the formatted output for readability.
  4. Copy the result for use in code, documentation, or a code review comment.
  • Clean up a long single-line query copied from an ORM's generated SQL or database log.
  • Make a complex JOIN-heavy query easier to review during a pull request.
  • Prepare a readable SQL example for internal documentation or a runbook.
  • Reformat a query pasted from Slack or a support ticket before debugging it.

Formatting happens entirely in your browser using text pattern matching. Your SQL is never uploaded.

  • Formats based on keyword pattern matching, not a true SQL parser — it doesn't validate syntax or catch errors.
  • Doesn't understand SQL dialect-specific syntax beyond common keywords, so unusual constructs may not break as expected.
  • Very long queries with deeply nested subqueries may produce output that still needs manual indentation cleanup.

SQL Formatter

SQL Formatter makes SQL queries easier to scan by adding line breaks around clauses, joins, and conditions. It is useful for debugging queries, docs, and code reviews.

FAQ

Frequently asked questions

Is SQL Formatter free to use?

Yes. The tool is free and runs directly in your browser with no account required.

Does this tool upload my data?

No. The query text is reformatted locally in the browser tab and is not sent to a server.

What is this tool best for?

Turning a single-line or copy-pasted SQL query into a readable version with clauses, joins, and conditions each on their own line.

Which SQL keywords does it break onto new lines?

SELECT, FROM, WHERE, GROUP BY, ORDER BY, HAVING, LIMIT, OFFSET, the JOIN variants (INNER/LEFT/RIGHT/FULL/plain JOIN), VALUES, and SET each start a new line, with AND/OR conditions and comma-separated lists indented beneath them.

Does it validate that my SQL is syntactically correct?

No — this is a text formatter based on keyword patterns, not a SQL parser. It reformats whitespace around recognized keywords but doesn't check whether the query would actually run.

Which SQL dialect does it support?

It works on standard ANSI SQL keyword patterns common to MySQL, PostgreSQL, SQLite, and SQL Server. Dialect-specific syntax (like T-SQL's TOP or PostgreSQL's DISTINCT ON) isn't specifically recognized but generally passes through unaffected.

Will formatting change what my query does?

No — it only adjusts whitespace and line breaks. Table names, column names, and query logic are left exactly as written.

Can I format a multi-statement SQL script?

The formatter processes the text you paste as a whole; multiple semicolon-separated statements will have their combined keywords broken onto new lines, but it's most reliable on one query at a time.
