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.
What this calculator does
- SQL Formatter (Readability)
- Indent and normalize simple SELECT-style SQL for readability.
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.
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.
Inputs on this page: SQL. Assumptions stay visible so you can reproduce the figure elsewhere.
When to use it
- Use SQL Formatter (Readability) when you need a transparent sql formatter online answer before you commit numbers to a spreadsheet, invoice, or conversation.
- Reach for it when you already know (or can estimate) SQL and want the dependent result without rebuilding the formula by hand.
- Skip it when you need certified advice, signed-off payroll, or a lender’s official quote—those require the primary institution’s systems.
Key takeaways
- 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.
How to use this tool
- 1Paste SQL into the text area.
- 2Click Calculate for a formatted draft.
- 3Manually verify strings and dialect-specific syntax after formatting.

FAQs
Click a question to expand the answer.
Does this understand every SQL dialect?
No; it applies generic rules; PL/pgSQL blocks, CTE edge cases, or vendor extensions may need manual touch-up.
Will this change my query semantics?
It should not, but you should always re-run validation in your SQL client or CI.
Can it minify SQL?
This tool focuses on readability (expand), not minification.
Does it format INSERT batches?
Partially; very large dumps are better handled in an editor or dedicated formatter.
Is my SQL sent to a server?
No; formatting runs locally in your browser session.
Will this fix syntax errors?
No; it only rearranges whitespace for common keywords.
Does it support stored procedures?
Complex procedural blocks may still need manual formatting.
What about long CTE chains?
Very deep nested WITH statements may need manual blank lines after each CTE so reviewers can scan bindings quickly.
