Formats SQL with the sql-formatter library, supporting several dialects. Everything runs locally in your browser.
- 1
Formatting is delegated to the `sql-formatter` library (loaded on demand when the page opens), with 2- or 4-space indentation. Minifying is a small local implementation that **only collapses whitespace — comments and string literals stay untouched**.
- 2
Comments are kept on purpose: in SQL a comment can be an optimiser hint (`/*+ INDEX(...) */`), and removing it can silently change the execution plan.
- 3
Whitespace inside a literal like `'a b'` is preserved too — that is data, not layout (fixed 2026-09-20; it used to collapse the three spaces into one).
- 1
Paste the SQL
The sample is a single SELECT; subqueries and joins are re-indented by the library.
- 2
Choose indentation or a mode
Format re-lays it out with 2 or 4 spaces; Minify collapses whitespace onto one line.
- 3
Copy the result
Both directions run locally, nothing is uploaded.
This page uses the library default, which is standard SQL. `sql-formatter` does support several dialects, but no switch is exposed here, so dialect-specific syntax (`LIMIT 1,2`, `::` casts, `\G`) may not lay out as you expect — reach for a dialect-aware wrapper or the library CLI in that case.
Deliberate. A SQL comment can be an optimiser hint (MySQL `/*+ ... */` for example), and dropping it can quietly change the query plan. This minifier only collapses whitespace and does not try to judge intent.
