What does SQL Minifier do?

SQL Minifier removes unnecessary formatting from SQL queries for compact storage or embedding.

  • Primary use: SQL Minifier removes unnecessary formatting from SQL queries for compact storage or embedding.
  • Key technical fact: SQL whitespace separates tokens, so minification must preserve spaces where identifiers, literals, and keywords would otherwise merge.
  • Practical check: Run the formatted or minified output through your parser, tests, or runtime when exact syntax behavior matters.

Compact SQL without merging tokens

SQL Minifier removes line breaks, indentation, and extra spaces so queries are easier to embed or store as compact strings. It is useful for fixtures, logs, generated SQL, and application constants.

SQL whitespace separates tokens. A safe minifier must keep spaces where keywords, identifiers, numbers, operators, and string literals would otherwise merge into different tokens.

How to use

  1. Paste your SQL query into the input editor.
  2. Click Minify SQL to collapse unnecessary formatting.
  3. Review the minified SQL to confirm identifiers, literals, comments, and operators still parse correctly.
  4. Use Copy for the clipboard, Download for a file, or Clear to reset.

What is SQL Minifier?

SQL Minifier is a browser-based utility for turning formatted SQL into a compact single-line query. It reduces visual size while preserving the spaces required for the database parser to understand the statement.

SQL dialects and comments vary across engines. Test important minified queries in the target database, especially when using hints, quoted identifiers, procedural SQL, or vendor-specific operators.

Input notes

Paste SQL text, not application string escapes or log metadata. Preserve comments only if your database or tooling depends on hints, annotations, or migration markers.

Example

A formatted query is reduced to one line while keeping spaces between SQL tokens:

--- Formatted Input ---
SELECT
  u.name,
  u.email
FROM users u
WHERE u.active = 1;

--- Minified Output ---
SELECT u.name, u.email FROM users u WHERE u.active = 1;

MCP integration

MCP (Model Context Protocol) lets AI agents and apps discover and run Coding.Tools utilities for repeatable conversions, formatting, hashing, and generation workflows.

MCP tool name: sql-minifier

MCP endpoint: https://coding.tools/mcp

Call tools/list first. Each tool entry includes inputSchema, outputSchema, and examples so an AI agent or client can build valid arguments without guessing.

For tools/call, read result.content[0].text for the display value and result.structuredContent for machine parsing. Tool-level failures return isError: true; protocol failures return a JSON-RPC error.

Example tools/call request:

curl -s https://coding.tools/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -H "MCP-Protocol-Version: 2025-06-18" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"sql-minifier","arguments":{"input":"select id, total\nfrom invoices\nwhere paid = 1\norder by total desc"}}}'

Most text and data tools accept an input string plus optional options. Browser-only image tools are listed for discovery and return a web UI link when they need browser image APIs.
