LOCAL SQL FORMATTER
Reformat common SQL clauses for easier reading.
Format common SQL clauses locally with preserved strings and comments. This layout helper does not validate SQL syntax or target a specific dialect.
SQL formatting runs locally in your browser.
Review the formatted query before using it.
How this SQL formatter works
The formatter tokenizes the query to keep single-quoted strings, quoted identifiers, and line or block comments intact. It uppercases a documented set of common SQL keywords, starts common clauses on new lines, and places top-level select-list commas on separate lines. For example, select id,name from users where active=true becomes SELECT.
id,
name
FROM users
WHERE active = true
This is a layout helper, not a SQL parser or validator. It does not target a particular database dialect, infer statement meaning, or guarantee that a query is valid. Nested expressions are kept together where practical. Inputs are limited to 100,000 characters and 50,000 tokens. Updated November 3, 2026.
Runs in your browser. No uploads. No account.
Good to know
Does this validate SQL syntax?
No. It adjusts whitespace and keyword casing for common clause patterns. Use your database or dialect-specific parser to validate a query.
Which SQL dialects are supported?
The formatter does not claim dialect support. It recognizes common SQL keywords and preserves quoted text, but vendor-specific syntax may not be styled as expected.
Are strings and comments changed?
Quoted strings, quoted identifiers, and comments are kept as tokens so keywords and commas inside them are not treated as SQL clauses or select-list separators. Surrounding whitespace can change.
Is my query uploaded?
No. Tokenizing and formatting run locally in this browser tab; the query is not uploaded or sent to an external service.
Is it free?
Yes, during beta. Optional usage-credit plans are coming soon. Payments are not available and no credits are required.

Keyword and comment handling follows the lexical elements described in PostgreSQL documentation; this page does not claim PostgreSQL parser compatibility. Sources checked November 3, 2026.
How it works
1. Paste a SQL query or load the example. 2. Choose two or four space indentation. 3. Format and review the result, then copy it if useful. Processing stays in your browser.

Methodology and limitations
Tokenize whitespace, common SQL words, quoted strings and identifiers, comments, punctuation, and operators. Uppercase a limited set of common keywords, break recognized clauses and top-level select-list commas onto lines, and indent logical conditions. Enforce 100,000-character and 50,000-token limits. This is not a dialect-aware parser or validator.
