Format SQL without leaving the browser. SQL Formatter reformats SQL with consistent indentation, keyword casing and clause breaks — useful when you need to reformat a dense query into a readable, review-friendly layout between two other steps of a debugging session. Everything runs inside your browser, so the file never touches a server, which matters when the payload contains tokens, customer records or anything else you would not paste into an unknown server.
How to
Four steps, no account, nothing to install.
Drop in the statement, however dense it is.
Set indentation and keyword casing to match your codebase.
Return the formatted query to your editor or pull request.
Overview
SQL describes what data you want rather than how to fetch it. Dialects differ — MySQL, PostgreSQL, SQL Server and SQLite each add their own syntax — but the core SELECT/JOIN/WHERE/GROUP BY shape is shared, which is why consistent formatting matters so much in code review.
Paste the query — Drop in the statement, however dense it is. Choose your conventions — Set indentation and keyword casing to match your codebase. Copy it back — Return the formatted query to your editor or pull request. The whole loop is designed to be repeatable: change the input, read the new result, no re-submit step in between.
The failures people hit are predictable: Dialect fragmentation; Long queries become unreadable fast; Easy to write accidental cross joins. Each of those shows up as a specific, fixable symptom rather than a vague error, which is exactly what this tool surfaces.
Reporting queries, Migrations and schema changes, Analytics dashboards — these are the contexts where SQL shows up, and this page is the fast path between "I have a blob of input" and "I understand what it contains". Keep the tab open next to your editor and your terminal.

Examples
Copy the raw payload out of the network tab, drop it in here, and read the result immediately — no curl round trip, no scratch file.
Paste the snippet from the diff to confirm what it evaluates to before approving the change.
Because processing is local, real payloads with real identifiers can be inspected without violating a data-handling policy.

No. Everything runs inside your browser, so the file never touches a server — safe for tokens, staging payloads and customer data.
Yes, with no account, no rate limit and no paid tier.
The declarative query language used to read and modify relational databases. Dialects differ — MySQL, PostgreSQL, SQL Server and SQLite each add their own syntax — but the core SELECT/JOIN/WHERE/GROUP BY shape is shared, which is why consistent formatting matters so much in code review.
