SQL Query Formatter & Beautifier

Turn a wall of one-line SQL into readable, consistently indented query text: keywords cased, joins and conditions aligned, subqueries nested. Covers the common dialects and runs entirely in your browser.

Everything happens locally in your browser. Nothing you paste is uploaded, logged or stored on our servers.

Product demo

Watch explai answer one real business question

A recording of the product itself. At the top, the question someone types in: roll a promotion that grew revenue 12% out across all European stores. Below it, explai's answer: it checks that claim against the real sales data, shows every reasoning step, and comes back with a chart and a clear recommendation against the rollout. Under 10 seconds, starts by itself, nothing to click.

That was one question, on our data. In measured deployments teams save about three hours per person a day, and a week of repeatable analysis comes back in roughly five minutes. A private sandbox is waiting for your data: upload a CSV and ask your first question in a few minutes.

FAQ

Questions people ask about this tool

How do I format an SQL query online?

Paste the query and it is re-indented immediately: keywords uppercased, SELECT columns broken onto their own lines, JOIN and WHERE conditions aligned. Nothing is executed and nothing is sent anywhere.

Which SQL dialects are supported?

The common ones: standard SQL, PostgreSQL, MySQL, T-SQL, BigQuery and Snowflake. The formatter only reshapes text; it never rewrites the logic of your query.

Can I format a query that contains real table and column names?

Yes. Formatting happens client-side, so the query text never reaches a server and is not logged.

Beyond the toolbox

Formatting takes minutes. The query backlog takes months.

Every data team carries a queue of ad-hoc questions that only they can answer. explai gives the business a trustworthy way to ask, and gives you the controls to govern what it answers.
