Improve readability of common SQL with keyword line breaks and light indentation. Best for ad-hoc queries and docs; always review before running against production.
Quick answer: SQL Formatter (Readability)
SQL formatter: insert line breaks before major keywords so a one-line log query becomes reviewable without touching semantics.
Example: SELECT id,name FROM users WHERE active=1 ORDER BY name → stacked SELECT / FROM / WHERE / ORDER BY lines for Slack snippets.
Calculations follow the documented formula on this page; rounding and input units can change the last digit-treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
Dialect quirks, string literals with reserved words, and dollar-quoted bodies can still surprise naive formatters - treat output as a draft you eyeball before execution.

Click a question to expand the answer.
No; it applies generic rules; PL/pgSQL blocks, CTE edge cases, or vendor extensions may need manual touch-up.
It should not, but you should always re-run validation in your SQL client or CI.
This tool focuses on readability (expand), not minification.
Partially; very large dumps are better handled in an editor or dedicated formatter.
No; formatting runs locally in your browser session.

CTEs and window clauses may need manual indentation after the first pass. Never auto-run formatted SQL against prod without the same guardrails as the original. Pair with your SQL client’s explain plan, not this whitespace layer, for performance tuning.
Same-category picks first, then high-intent neighbors that often answer the next calculation question.
