Beautify messy SQL by uppercasing keywords and putting major clauses on their own lines for readability.

How to use
Paste or type your text into the box above, then read or copy the result. Everything runs privately in your browser, your text is never uploaded to a server.
How to use this tool
- Paste your SQL query into the input box.
- Choose the format or beautify action for the tool.
- Review the formatted query and copy it back into your editor or database client.
- Run your query again if you change the SQL and want the same clean layout.
Step by step, what happens
- The tool reads your SQL text and identifies common clauses like SELECT, FROM, WHERE, ORDER BY, and JOIN.
- It rewrites the query with uppercase SQL keywords and places major clauses on separate lines for easier scanning.
- It adds indentation around nested parts so the structure is easier to follow.
- It returns a cleaned version of the same query without changing the intended SQL logic.
Worked example
Here is a small query that is hard to read when it is all on one line.
Input: select id,name from users where active=1 order by name
- The tool recognizes the SELECT, FROM, WHERE, and ORDER BY clauses in the one-line query.
- It uppercases the SQL keywords and breaks the clauses onto separate lines.
- It keeps the column names and table names as written, while improving the layout for readability.
Output: SELECT id, name
FROM users
WHERE active = 1
ORDER BY name
Tips and common mistakes
- Paste only the SQL you want formatted, because extra notes or error messages can make the output messy.
- If your query has subqueries or joins, format it after the full query is complete so the indentation is applied consistently.
- This tool improves readability, but it does not fix invalid SQL syntax, so check your query if formatting looks incomplete.
- If you use aliases or database-specific keywords, review the result to make sure the style still matches your team's conventions.
