SQL Formatter & Beautifier

Turn a one-line SQL blob into a readable, properly indented query. Supports SELECT, INSERT, UPDATE, DELETE, CTEs, joins, subqueries and window functions.

Input SQL0 chars
Output0 chars

Why format SQL?

A readable query is easier to review, easier to debug, and easier to reason about during performance tuning. Formatting puts each major clause on its own line, indents subqueries, and breaks column lists into a vertical stack — making it trivial to spot missing columns, mis-grouped conditions, or stray joins.

What's supported

  • SELECT / INSERT / UPDATE / DELETE including multi-table joins.
  • CTEs (WITH clauses) — including recursive CTEs.
  • Subqueries in FROM, WHERE, and SELECT — indented for readability.
  • CASE / WHEN / THEN / ELSE / END blocks — formatted on separate lines.
  • JOINs of every kind (INNER, LEFT, RIGHT, FULL, CROSS).
  • UNION / INTERSECT / EXCEPT operators.
  • Line & block comments (-- ... and /* ... */) are preserved.
  • String literals — single and double quotes, backticks, escape sequences.

Style options

  • Keyword case — UPPER (default), lowercase, or keep as written.
  • Leading commas — place commas at the start of each line (  , name) instead of the end. Helps when adding/removing columns during code review.
  • Indent size — 2 spaces, 4 spaces, or tab.

Privacy

Your query stays in your browser. Nothing is uploaded, logged, or analysed. Safe to paste queries that reference internal table names, schemas, or production data.
