About

About this tool: SQL Formatter

Paste SQL, choose a common dialect where available, then format it for readability or compact whitespace for copying. The tool never sends or executes your SQL.

It is intended for development and data-cleanup workflows, with errors kept inside the interface so malformed input does not crash the page.

SQL Formatter is presented in the shared NexterHub tool layout so the working controls stay near the top while the method, example, limitations and related utilities remain available below the result.

How it works

The sql-formatter library tokenizes the SQL according to the selected language rules, adds indentation and normalizes keywords to uppercase for this interface.

Practical example

A single-line SELECT with WHERE and ORDER BY clauses can be expanded into readable lines with uppercase SQL keywords.

Important notes

Validate the output in the context where you will use it, especially when the source data is incomplete or uses an unsupported syntax variant.

Privacy & processing

The primary formatting, parsing, encoding or conversion logic for this tool runs in the browser in the current build.
