Format and beautify SQL queries instantly. Supports indentation, keyword casing, and multi-dialect SQL. SQL Formatter & Beautifier — Instant Query Cleanup Right in Your Browser Stop wrestling with messy, unreadable SQL. SQL Formatter & Beautifier is a lightweight Chrome extension that turns tangled, single-line SQL dumps into clean, perfectly indented, human-readable queries in under a second — no server, no copy-pasting into external websites, no signup required. This SQL formatter is the fastest way to make sense of a complex query without leaving your current tab. HOW IT WORKS Paste any SQL query — SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, or deeply nested JOIN chains — into the input box and click Format SQL. The SQL formatter instantly restructures your query: each main clause starts on its own line, AND and OR conditions are indented under WHERE, SELECT column lists are split onto separate indented lines for easy scanning, and all keywords are uniformly cased. Click Copy and the polished query lands on your clipboard, ready to paste into your database client, code editor, Confluence page, or pull request comment. KEY FEATURES Instant formatting — no latency, no network request, the SQL formatter works fully offline and never communicates with external servers. Indent control — choose 2-space or 4-space indentation in the SQL formatter to match your team style guide or the linter rules already in your project. Keyword casing — force every SQL keyword to UPPERCASE or lowercase with a single radio button click, keeping your codebase consistent. One-click copy — send the formatted output to your clipboard without selecting any text manually. Clear button — wipe both the input and output fields at once when you want to start fresh. Keyboard shortcut — press Ctrl+Enter on Windows or Linux, Cmd+Enter on Mac, to trigger formatting without reaching for the mouse. Smart clause detection — the SQL formatter correctly handles multi-word keywords such as LEFT OUTER JOIN, RIGHT JOIN, INNER JOIN, INSERT INTO, DELETE FROM, GROUP BY, ORDER BY, and UNION ALL. No mis-split keywords, no broken output. SELECT column list splitting — the SQL formatter places columns listed after SELECT on separate indented lines, so a ten-column query is readable at a glance. Zero permissions — the SQL formatter requests no access to your browsing data, open tabs, clipboard history, or any website you visit. WHO IS IT FOR Database developers who write SQL every day and hate reformatting legacy dumps by hand before they can read them. Data analysts receiving single-line exports from BI tools who need to understand a query in two seconds. Backend engineers staring at ORM-generated SQL trying to figure out why a query is slow. DBAs performing code review on stored procedures before pushing a release to production. Developers writing technical documentation who want SQL examples to look clean and professional. Students learning SQL who want their practice scripts to look as readable as their instructor's examples. If you read or write SQL daily, this SQL formatter belongs in your toolbar. PRIVACY FIRST SQL Formatter & Beautifier requests zero browser permissions. It cannot inject scripts into web pages, cannot read your browsing history, cannot access your open tabs, and cannot see anything you do outside the extension popup. Every operation of the SQL formatter runs inside the popup window using pure JavaScript — no data is ever sent to a remote server. The extension contains no analytics code, no advertisement libraries, and no third-party SDKs. Your queries are yours alone. SUPPORTED SQL The SQL formatter handles standard ANSI SQL plus common dialects from MySQL, PostgreSQL, SQLite, Microsoft SQL Server, and Oracle. It recognises over eighty keywords: aggregate functions (COUNT, SUM, AVG, MAX, MIN), string functions (CONCAT, TRIM, SUBSTRING, REPLACE), date functions (NOW, DATE, YEAR, MONTH, DAY), type conversion (CAST, CONVERT, COALESCE), DDL statements (CREATE TABLE, ALTER TABLE, DROP TABLE, ADD COLUMN), and conditional expressions (CASE, WHEN, THEN, ELSE, IF, EXISTS). GETTING STARTED Pin the SQL Formatter icon to your Chrome toolbar. Click it, paste your query, choose indentation and keyword casing, then press Format SQL or Ctrl+Enter. Copy the result. Done — the whole flow takes under five seconds. Install the SQL formatter now and turn every unreadable SQL wall into clean, scannable code.
