How to use
How to turn dense SQL into readable clauses and quickly clean up query text
- 1 Paste a SQL statement or a collection of statements into the input area, including SELECT, INSERT, UPDATE, or DDL queries.
- 2 Choose whether keywords should be uppercased or lowercased so the output matches your team preference.
- 3 Click Format to place major clauses such as SELECT, FROM, WHERE, JOIN, and ORDER BY on separate lines.
- 4 Use Minify when you need a compact query string for logs, quick testing, or transport inside another tool.
- 5 Copy the output and review complex conditions, joins, and subqueries with much less visual noise than the original source.
SQL becomes hard to review when long joins, conditions, and nested queries are compressed onto one line. A formatter improves readability by separating the major clauses that matter most during debugging: where rows come from, how tables are joined, what filters are applied, and how results are grouped or ordered. That makes it easier to catch missing conditions, compare query versions, or walk someone else through a statement during code review.
Keyword case is another small but useful detail. Some teams prefer uppercase SQL commands because they stand out against identifiers, while others keep everything lowercase to match application code style. This formatter supports both approaches while also offering a minify mode for the opposite task: shrinking a readable query into a compact string for quick copying, logging, or embedding in test fixtures.
