What is sql beautifier online?

A sql beautifier online (SQL formatter) takes SQL text and applies consistent, readable styling: uppercases keywords, breaks long clauses onto new lines, aligns JOINs, indents subqueries, and standardizes commas and operators. Beyond readability, good formatting reduces review time, surfaces logical errors earlier, and makes diffs cleaner in code review. The AI2sql platform goes further by pairing formatting with dialect selection, schema awareness, and a validator so you catch structural and semantic issues before they hit production.

Compared to manual formatting, AI2sql standardizes code style across teams, adapts to each engine, and explains what the query does so both beginners and experts move faster.

Real sql beautifier online Examples (copy-paste)

Below are runnable examples for multiple databases. Paste your own SQL into AI2sql to beautify, validate, and explain it. Example captions include business context so you can adapt them to your dataset.

Business context: Marketing needs monthly revenue by channel for the last 12 months. Use the sql beautifier online to keep joins and grouping readable. Engine: MySQL

SELECT DATE_FORMAT(o.order_date, '%Y-%m') AS month,
       c.channel,
       SUM(o.amount) AS revenue
FROM orders o
JOIN customers c ON c.id = o.customer_id
WHERE o.status = 'paid'
  AND o.order_date >= DATE_SUB(CURDATE(), INTERVAL 12 MONTH)
GROUP BY month, c.channel
ORDER BY month, revenue DESC;

Business context: Identify the top product per category by sales in the last 90 days for a category leaderboard. Engine: PostgreSQL

WITH s AS (
  SELECT p.category_id,
         p.product_id,
         SUM(oi.quantity * oi.unit_price) AS sales
  FROM order_items oi
  JOIN orders o ON o.id = oi.order_id
  JOIN products p ON p.id = oi.product_id
  WHERE o.status = 'paid'
    AND o.order_date >= CURRENT_DATE - INTERVAL '90 days'
  GROUP BY p.category_id, p.product_id
)
SELECT category_id, product_id, sales
FROM (
  SELECT s.*,
         ROW_NUMBER() OVER (PARTITION BY category_id ORDER BY sales DESC) AS rn
  FROM s
) ranked
WHERE rn = 1;

Business context: Product analytics wants daily active users by country from nested JSON metadata. Engine: Snowflake

SELECT DATE_TRUNC('day', event_time) AS day,
       value:'country'::string AS country,
       COUNT(DISTINCT user_id) AS dau
FROM events, LATERAL FLATTEN(input => events.metadata)
WHERE event_time >= DATEADD('day', -7, CURRENT_TIMESTAMP())
GROUP BY day, country
ORDER BY day;

Business context: Measure campaign conversion rate from visits to purchases over the last 30 days. Engine: BigQuery

SELECT DATE(event_ts) AS day,
       campaign,
       SAFE_DIVIDE(SUM(CASE WHEN event = 'purchase' THEN 1 ELSE 0 END),
                   SUM(CASE WHEN event = 'visit' THEN 1 ELSE 0 END)) AS conv_rate
FROM analytics_events
WHERE event_ts >= TIMESTAMP_SUB(CURRENT_TIMESTAMP(), INTERVAL 30 DAY)
GROUP BY day, campaign
ORDER BY day;

Business context: CRM operations needs to update customer tier based on lifetime spend. Engine: MySQL

UPDATE customers c
JOIN (
  SELECT o.customer_id, SUM(o.amount) AS total_spend
  FROM orders o
  WHERE o.status = 'paid'
  GROUP BY o.customer_id
) s ON s.customer_id = c.id
SET c.tier = CASE
  WHEN s.total_spend >= 5000 THEN 'gold'
  WHEN s.total_spend >= 1000 THEN 'silver'
  ELSE 'bronze'
END;

Business context: HR needs a reporting view of org depth to understand management layers. Engine: PostgreSQL

WITH RECURSIVE org AS (
  SELECT id, manager_id, 1 AS depth
  FROM employees
  WHERE manager_id IS NULL
  UNION ALL
  SELECT e.id, e.manager_id, o.depth + 1
  FROM employees e
  JOIN org o ON e.manager_id = o.id
)
SELECT id, depth
FROM org
ORDER BY depth DESC;

Best Practices and Limitations

• Set the target database before formatting so functions and date math are dialect-accurate.

• Prefer CTEs for complex logic; they format cleanly and make reviews easier.

• Use consistent aliasing; avoid ambiguous column names that obscure intent.

• Formatting improves readability but does not guarantee correctness; use AI2sql validation and explanations to confirm logic.

• Review execution plans (EXPLAIN) for heavy queries; formatting will not compensate for missing indexes.

• Keep sensitive data out of prompts; use representative schema snippets and sample values.
