SQL Formatter

SQL Formatter turns dense, single-line or inconsistently written SQL into readable, review-friendly queries. It puts each major clause — SELECT, FROM, WHERE, JOINs, GROUP BY, ORDER BY, HAVING, LIMIT, UNION — on its own line, breaks SELECT columns onto separate lines, indents AND/OR conditions under their clause, and normalizes keyword casing to upper or lower. The result is the kind of layout you would want in a code review: a 400-character query from an ORM log becomes a structure you can actually scan for the missing join condition.

Under the hood it is a real tokenizer, not a pile of find-and-replace rules. String literals (including doubled-quote and backslash escapes), double-quoted and backtick-quoted identifiers, bracketed SQL Server identifiers, numbers, operators and both comment styles (-- line and /* block */) are lexed as atomic tokens before any layout decision is made. That means a column value like 'SELECT * FROM users' inside a string is never mistaken for a clause, and formatting can restructure whitespace without ever corrupting literal content.

The Minify mode does the opposite: it collapses a formatted query to a single line — dropping comments, preserving every literal byte-for-byte — which is handy for log grepping, packing queries into JSON payloads or .env files, and comparing query shapes. Everything runs 100% client-side in your browser, so production queries containing table names, customer data in literals or schema details are never uploaded, logged or stored anywhere.
