What is a SQL Formatter?
Format messy SQL into readable, consistently indented queries. Runs entirely in your browser. This tool re-indents and organizes code according to standard style conventions while checking for syntax validity. Everything executes 100% inside your browser, guaranteeing zero latency and complete privacy for API keys, user tokens, and confidential database schemas.
SQL formatters turn dense queries into reviewable text so joins, filters, and CTEs are obvious at a glance. This tool supports common dialects and keeps processing local so production queries never leave your machine.
Common errors and fixes
syntax error at or near ","
Remove a trailing comma in the SELECT list or VALUES clause.
Unclosed quotation mark
Balance single quotes around string literals; escape quotes by doubling them in SQL.
Incorrect syntax near ")"
Check for an extra closing parenthesis or a missing expression before it.
Invalid column name
Verify identifiers and aliases; dialect options change how identifiers are quoted.
Options Explained
| Option | Description |
|---|---|
| SQL dialect | Dialect affects how reserved words, string quoting, and functions are parsed. |
| Indent size | Number of spaces per indent level. |
| Keyword case | Most SQL style guides use uppercase keywords for readability. |
Frequently Asked Questions
Is my SQL sent to a server?
No. All formatting runs inside your browser using JavaScript. Your query never leaves your machine.
Which SQL dialects are supported?
Standard SQL, MySQL, PostgreSQL, SQLite, BigQuery, and SQL Server T-SQL.
Why does my formatted query look different from my team's style?
Adjust indent size and keyword case in the options panel. Settings persist in your browser.
Can I format a stored procedure?
Yes, though procedural extensions like PL/pgSQL are formatted on a best-effort basis.
Is there a size limit?
Files under 5MB format directly in the editor. Larger files are processed in a background worker and offered as a download.
