Code Comments Stripper
Code Comments Stripper: Lexically tokenizes source code while stripping single-line and multi-line comment blocks.
About this code comments stripper
Lexically tokenizes source code while stripping single-line and multi-line comment blocks Transforms and validates developer data structures locally, preventing confidential payload exposure during data wrangling.
Syntax parsing & data transformation logic
Reads source text and strip/extract mode, scans for // and /* */ comments while preserving simple quoted strings, then returns comment-free code or extracted comment text. It is a bounded lexical scanner, not a language parser.
Worked conversion & output example
Scenario: Remove one line and one block comment while retaining a quoted URL.
Sample input:
Processing: Choose strip in the second field; lexical states preserve quoted text and remove comment states.
Illustrative output:
Syntax constraints & input size limits
This is a small lexical scanner, not a language parser. Extract mode reassembles comment markers and spacing rather than preserving exact source bytes. It does not understand regex literals, template interpolation, nested comments or all language-specific quoting; important code may change unexpectedly.
Data conversions and formatting in Code Comments Stripper reflect standard structured syntax. Verify parsed outputs against your target runtime before deployment.
Local client execution boundary
Data parsing and transformations in Code Comments Stripper execute in the local browser tab without remote data transmission.
Data format specifications & language standards

How to use it
- Paste code and optionally choose extract mode.
- Scan for `//` and `/* ... */` outside single, double and backtick strings.
- Read stripped code or extracted comment text.
Frequently asked questions
How does Code Comments Stripper recognize comments?+
It scans characters with code, line-comment, block-comment, and quoted-string states. It removes `//` and `/* */` only outside single-quoted, double-quoted, or template strings, while preserving escaped string characters.
Can you show an input and its result?+
With a quoted `https://czoa.com`, one line comment, and one block comment, strip output retains the URL string and `console.log(url);` while removing both comments.
What does extract mode return?+
With `extract` in the second field, the scanner returns collected comments instead of code. It adds `// ` or `/* ` prefixes and a ` */` closer for closed block comments, then trims the combined text; spacing is normalized rather than a byte-for-byte copy. Any other mode strips comments from code.
What language syntax is outside its scope?+
This is a lexical scanner, not a JavaScript or multi-language parser. It does not correctly model regular-expression literals, every language escape rule, comments nested by a language, syntax validity, or files.
