A one-line SQL query dumped out of an ORM's debug log or a slow-query log is barely readable. A decent formatter turns it back into something you can actually review.
| Tool | Consistent indentation | Keyword casing options | Runs fully in your browser | Free |
|---|---|---|---|---|
| iLoveDevTools | Yes | Yes | Yes | Yes |
| Typical online SQL beautifiers | Yes | Varies | No (server round-trip) | Mostly, with ads |
The SQL Formatter takes a dense or minified query and reflows it into readable, consistently indented SQL — useful for reviewing generated queries, pasting into a PR description, or just making sense of something a teammate sent you in a Slack thread. It runs client-side, so query text (which can contain real table and column names, sometimes real data in WHERE clauses) never leaves your browser.
Most of the free ones online do the basic reindent-and-uppercase-keywords job adequately, but they route your query through a server to do it, and many are ad-heavy pages built around the tool rather than the tool itself.
For most day-to-day query cleanup, iLoveDevTools's SQL Formatter does the job without sending query text — which can include real schema and data — off your machine.
