SQL Formatter
Paste an SQL query and instantly format, minify, normalize keywords, and improve readability directly in your browser.
What is an SQL formatter?
An SQL formatter makes SQL queries easier to read by adding indentation, line breaks, and consistent keyword styling.
It is useful for debugging queries, reviewing joins and filters, sharing SQL in tickets or pull requests, and cleaning up copied database statements.
How to use the SQL Formatter
- Paste your SQL query into the input field.
- Choose formatting options such as uppercase keywords, comma line breaks, and indentation size.
- Click Format to beautify the query or Minify to compress it.
- Copy the output and use it in your editor, docs, or database tool.
Tips
- Formatting does not change the logic of your SQL query.
- Uppercase keywords make long queries easier to scan.
- Breaking lines on commas helps with SELECT, GROUP BY, and ORDER BY lists.
- Minified SQL is useful when you need compact one-line output.

SQL formatting checks before sharing or reviewing queries
Formatting SQL improves readability, but query behavior depends on dialect, parameters, comments, and execution context.
Know the dialect
Check whether the query targets PostgreSQL, MySQL, SQLite, SQL Server, or another dialect before relying on formatting.
Preserve parameters
Keep placeholders, bind variables, template tags, and comments intact when formatting queries from application code.
Review risky clauses
Inspect WHERE, JOIN, GROUP BY, ORDER BY, LIMIT, UPDATE, and DELETE clauses before running copied SQL.
Do not expose data
Remove credentials, tokens, emails, and customer data before sharing formatted SQL in tickets or documentation.
Privacy and usage
Built for quick checks without an account
Toolinix tools are designed for short developer tasks: paste a safe sample, inspect the result, copy what you need, and move on.
No login required
You can use the tools without creating an account, subscribing to a newsletter, or saving a workspace.
Local when possible
Formatters, generators, encoders, and text utilities generally run in your browser. Network diagnostics may need a server-assisted lookup to check public URLs, domains, or IPs.
Keep secrets out
Do not paste production passwords, private keys, access tokens, customer records, or regulated data into online tools unless your own security policy allows it.
