SQL Formatter & Beautifier
Format, beautify, and minify SQL queries online. Syntax highlighting with colour-coded keywords, strings, numbers, and comments. Configurable indentation, 5 sample queries, and query statistics. Free. No sign-up.
How it works
- 1Paste or upload your SQL
Paste a SQL query into the input area, upload a .sql file, or pick from five pre-built sample queries covering SELECT, JOIN, subquery, INSERT, and CREATE TABLE statements.
- 2Format or minify
Choose your preferred indentation style (2 spaces, 4 spaces, or tabs), then click Format to beautify with proper structure or Minify to collapse into a single line.
- 3Review and export
View syntax-highlighted output with colour-coded keywords, strings, and numbers. Check query stats (characters, lines, keywords, tables), then copy or download the result.
Why You Need a SQL Formatter
SQL queries written in a single line or with inconsistent formatting are notoriously difficult to read, debug, and review. When a query spans hundreds of characters with no line breaks, finding a missing JOIN condition or an incorrect WHERE clause becomes a time-consuming exercise in character-by-character scanning. A SQL formatter solves this by applying consistent structure to any query.
Properly formatted SQL puts each major clause (SELECT, FROM, WHERE, JOIN, ORDER BY, GROUP BY) on its own line, indents sub-clauses like ON conditions and AND/OR predicates, and uppercases all SQL keywords for instant visual distinction from table names and column names. This consistent structure makes code reviews faster, reduces bugs from misplaced conditions, and helps teams maintain readable query libraries.
The minify function is equally useful. When embedding SQL in application code, configuration files, or API parameters, a single-line query reduces visual noise and avoids line-break issues in string concatenation. The minifier strips comments and collapses all whitespace while preserving the query logic.
Syntax highlighting adds another layer of readability. Keywords in blue, strings in green, numbers in orange, and comments in grey let you scan a query visually and spot patterns, misplaced literals, or uncommented debug code at a glance. The query statistics panel counts characters, lines, keywords, and detected table names to give you a quick overview of query complexity.
