Formatted SQL

SELECT
  u.id,
  u.email,
  count(o.id) AS orders,
  sum(o.total) AS revenue
FROM users u
LEFT JOIN orders o
  ON o.user_id = u.id
    AND o.status = 'paid'
WHERE u.created_at >= '2026-01-01'
  AND (u.country = 'US' OR u.country = 'CA')
GROUP BY
  u.id,
  u.email
HAVING count(o.id) > 2
ORDER BY revenue DESC
LIMIT 50;

Formatted in your browser. It lays out SQL and never runs it or checks it against a database, so a syntax error passes through as written. String values, quoted names and comments are kept exactly.

Run it from your agent

Copy one prompt, give it to your agent.

Fill in the placeholder, paste it, and the agent runs the same job with current data on your looot account and shows the cost.

You give it: a sql query.
Billed per call, nothing while your agent is idle.
The agent shows the price before it calls.

Prompt: SQL formatter

Use looot to review the SQL my agent wrote for a report. 1. Set up https://looot.ai/skill.md. 2. Format this query with one clause per line: [paste SQL]. 3. Explain what each clause does in one line. 4. Flag a missing WHERE on UPDATE or DELETE, SELECT star on a wide table and a join without a condition. 5. Return the formatted query and the flags.

Give this to your agent

FAQ

Questions about sql formatter

Paste it in the box. The formatted query appears as you type, with each clause on its own line. Copy it or download a .sql file.

Standard SQL, PostgreSQL, MySQL and MariaDB, SQL Server, SQLite and BigQuery. The dialect sets how quotes and comments are read: backticks in MySQL, square brackets in SQL Server, dollar-quoted strings in PostgreSQL and # comments in MySQL.

No. It lays out the text and never runs or parses it against a schema, so a typo stays a typo. Run the query in your database to check it.

No. Quoted strings, quoted names and comments are kept exactly as written, even when they contain commas or keywords.

Yes. Keywords can be UPPER CASE, lower case or kept as written. Table and column names are never changed.

It removes comments and line breaks and puts the query on one line with single spaces, for logs, string literals or a quick paste into a chat.

Partly. Queries inside a procedure are formatted, but BEGIN, END, IF and loops keep a simple layout. It is built for queries and DML, not procedural code.

No. Formatting runs in your browser, so queries with real table names stay on your machine.
