SQL Minifier & Escape: Removes single-line `--` and multi-line `/* */` comments, and collapses multi-line whitespace into single spaces.
About this sql minifier & escape
SQL Minifier & Escape — browser-based utility.
How this tool works
Implements client-side SQL Minifier & Escape operations. Removes single-line `--` and multi-line `/* */` comments, and collapses multi-line whitespace into single spaces specifically designed for a developer strips comments and unnecessary whitespace from an sql query to embed inside a compact source file.
- Lexical Tokenization: Deconstructs SQL text into keywords, identifiers, string literals, operators, comments, and delimiters.
- AST Clause Chunking: Organizes tokens into relational algebra blocks (projection, join conditions, filtering predicates, aggregations).
- Dialect-Specific Pretty Printing: Applies consistent tab/space indentation, uppercase keyword normalization, and newline splitting.
- Integrity Verification: Verifies that string literals, inline comments, and quote pairs remain completely untouched.
Worked example
Scenario: Remove lexical SQL comments and collapse whitespace.
Sample input:
Processing: Remove the implemented line and block comment matches.
Illustrative output:
Limits and verification
Preserves string literals containing SQL keywords without alteration. Unclosed quotes or unclosed multi-line comments (/* ... */) trigger explicit syntax warnings. Does not alter query execution semantics or rewrite table names.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
How does SQL Minifier remove text?+
It removes substrings matching `--` line comments and non-greedy `/* ... */` block comments, then collapses remaining whitespace to single spaces and trims the result.
How does SQL Minifier handle a query with comments?+
A multiline query containing `--` and `/* ... */` comments becomes `SELECT id, name FROM users WHERE active = 1;`. It removes those two comment forms and collapses whitespace; it does not validate SQL syntax.
What input and output does SQL Minifier use?+
It uses one text input and Run locally to emit a compact SQL-looking string. It does not execute SQL, connect to a database, choose a dialect, preserve source layout, or report a query plan.
Which SQL inputs need care?+
The minifier is not quote-aware and does not validate syntax, so comment markers inside a string literal can be removed. Use only reviewed input whose lexical comment boundary is acceptable.
