A well-structured SQL query is easier to read, debug, and review. Our free SQL formatter transforms raw, unindented SQL into clean, consistently styled code in milliseconds — directly in your browser, with no installation required and no data sent to any server. Paste a query, click Format, and get back production-ready SQL instantly.
A SQL formatter tool parses your SQL statement and re-outputs it with proper indentation, normalized keyword casing, and logical line breaks. Rather than manually aligning everySELECT,FROM, andJOINclause by hand, you paste your query and the formatter does the work — the same way Prettier formats JavaScript or Black formats Python, but built specifically for SQL.
Raw SQL quickly becomes hard to maintain. A long SELECT with nested CTEs, multiple subqueries, and a dozen JOIN conditions collapsed into a single block is nearly unreadable. A good online SQL formatter solves this by:
Unlike installable tools such as the Redgate SQL Formatter (an SSMS plugin) or the Poor SQL Formatter (a .NET desktop tool), this instant SQL formatter runs entirely in your browser. Nothing to download, no account to create — a truly free SQL formatter you can use from any device.
Not all SQL is the same. Oracle'sROWNUM, Snowflake's QUALIFY, and BigQuery's ARRAY<STRUCT<>>each require dialect-aware parsing. This SQL formatter & beautifier online supports:
NVL,SYSDATE,CONNECT BY, and PL/SQL procedural blocksThis SQL formatter online free tool is built for real teams with real style guides. Click Options in the toolbar to configure every aspect of output:
Beyond beautification, the toolset includes a SQL Minifier that compresses queries by stripping all whitespace and comments — ideal for embedding SQL in application configs or environment variables. The SQL Diff viewer lets you compare two versions of a query side-by-side with syntax highlighting to pinpoint exactly what changed. Additional utilities include instant clipboard copy, .sql file upload, and shareable URLs that encode your query for easy sharing with teammates. Whether you need thebest SQL formatter for daily development, a quickSQL formatter online free you can bookmark, or a tool that handles every database engine your team uses — this is it. No sign-up. No plugins. Just paste and format.
Paste your SQL into the left-hand INPUT editor, select your SQL dialect from the dropdown at the top, then click the Format button or press Ctrl+Enter.
The formatter instantly re-indents your query, normalises keyword casing, and breaks long lines at logical clause boundaries. Click Options in the toolbar to fine-tune indent width, keyword case, line width, and more.
Ctrl+Enter to trigger formatting on demand..sql file, or click the Share icon to generate a shareable URL.The formatter automatically handles the most common pre-processing issue: if your SQL contains literal escape sequences like \n, \t, or \r — common when pasting queries copied from JSON configs, log output, or string variables in application code — the tool detects and expands them to real whitespace before beautifying.
For other cleanup such as stripping parameter placeholders, replacing bind variables (:1, ?, $1), or removing application-level comments, paste the pre-cleaned SQL directly into the editor before clicking Format. The formatter never modifies the content of string literals or SQL comments.
There are three common causes:
ROWNUM, CONNECT BY, or NVL need the Oracle (PL/SQL) dialect — selecting Standard SQL will produce incorrect or incomplete output.Over 20 dialects are supported. Select from the dropdown before formatting:
Yes. Paste multiple statements separated by semicolons (;) into the editor and click Format. The formatter processes all of them in a single pass, preserving the statement order.
Use the Lines between queries option (under Options) to control how many blank lines are inserted between each statement in the formatted output — useful for visually separating large migration scripts.
Yes — completely free, with no sign-up, no subscription, and no rate limits. All formatting runs locally in your browser using JavaScript; no SQL is ever transmitted to a server, so your queries remain entirely private.
You can bookmark the page and use it as many times as you need. There are no hidden limits on query size, number of statements, or number of uses.
When Oracle (PL/SQL) is selected as the dialect, the formatter recognises Oracle-specific syntax including NVL, SYSDATE, ROWNUM, CONNECT BY, DECODE, and basic BEGIN/END block structures.
For complex procedural blocks containing nested loops, cursors, or exception handlers, the formatter applies best-effort indentation. It is primarily optimised for SELECT, INSERT, UPDATE, DELETE, and DDL statements — procedural results may vary.
Click the Share button (link icon) in the toolbar. The tool encodes your current query into a URL that you can copy and send. Anyone who opens the link sees the same SQL pre-loaded in the editor — no account or login required.
Note: the URL encoding has a practical limit of around 5,000 characters. For very large queries, use the Download button to save a .sql file and share that instead.
Formatting (beautifying) expands a SQL query with consistent indentation, line breaks, and keyword casing to make it easy for humans to read, review, and maintain.
Minifying does the opposite — it strips all whitespace and comments to produce the shortest possible SQL string. Minified SQL is ideal for embedding queries in application configs, environment variables, or API payloads where extra whitespace is unnecessary overhead.
Use the SQL Minifier tab for compression, and this formatter for readability.
