Frequently Asked Questions
Does this SQL formatter support stored procedures?
The formatter handles standard SQL including SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, and JOIN queries. Complex stored procedure syntax with BEGIN/END blocks, IF/ELSE, and DECLARE statements is formatted as best-effort.
What is the difference between beautify and minify?
Beautify adds line breaks, consistent indentation, and keyword casing for human readability. Minify removes all extra whitespace to produce the smallest possible query string — useful for embedding in code or measuring query length.
Should SQL keywords be uppercase or lowercase?
Both styles are equally valid — SQL is case-insensitive. The convention of UPPERCASE keywords (SELECT, FROM, WHERE) is traditional and widespread because it visually separates reserved words from table/column names. Many style guides (like Google SQL Style Guide) prefer lowercase for everything.
Does formatting change how the query runs?
No. Formatting only affects whitespace and keyword case — it has no effect on query execution, performance, or results. The SQL engine ignores whitespace.
Is my SQL query sent to a server?
No. All formatting runs entirely in your browser using JavaScript. Your SQL code never leaves your device.
