Is my SQL uploaded anywhere?

No. The formatter runs entirely in your browser using JavaScript. Your query is never sent to a server, so it is safe to format queries that reference sensitive table or column names.

How accurate is the formatting?

The tool tokenises on whitespace, parentheses and quotes, then emits each major clause (SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY and so on) on its own line with the body indented. It re-lays-out the query but does not parse or validate the SQL, so it will not catch syntax errors.

Does it change string literals?

No. Quoted strings and identifiers ('...', "...", `...`) are detected during tokenisation and copied through verbatim, so their contents and casing are never altered.

SQL Formatter & Beautifier

SQL formatter and beautifier

Paste a cramped one-line SQL query and get back a readable layout: each major clause — SELECT, FROM, WHERE, the JOIN family, GROUP BY, ORDER BY, LIMIT and more — on its own line, recognised keywords upper-cased, and AND/OR plus SELECT-list commas broken onto indented continuation lines.

It is privacy-first: the formatter is plain JavaScript that runs in your browser, so your query never leaves your device. String literals and quoted identifiers are preserved exactly — only layout and keyword casing change.
