HTML comment extraction workflows
Use comment extraction when hidden template notes, migration markers, or developer TODOs need a quick pasted-markup inventory.
Clean template notes
Pair this with HTML Formatter before removing stale inline notes from copied templates.
Inventory surrounding copy
Use Extract HTML Headings and Extract HTML Paragraphs to review visible content separately.
Finish cleanup
Send copied comments to Remove Duplicate Lines, Sort Lines, or Remove HTML Tags.
What this tool does
Extract HTML Comments finds <!-- comment --> blocks in pasted HTML, strips comment wrappers, removes duplicates, shows source lines, and runs locally in your browser.
Common use cases
Extract hidden HTML comment text from pasted templates, CMS output, component snippets, email markup, and copied source before cleanup, migration, QA review, or documentation handoffs.
Use Extract HTML Comments when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Paste HTML templates, CMS snippets, component output, email markup, or copied source that may contain comment blocks.
- Choose whether duplicate comments should be removed and whether comment text should be normalized for comparison.
- Review the extracted comment text with source lines, then copy the clean list for cleanup, migration, or QA notes.
Example workflow
Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.
Privacy note
HTML comment extraction runs locally in your browser. ClearUtils does not upload, store, fetch, crawl, render, execute, or log the HTML you paste.
FAQ
Does Extract HTML Comments execute my HTML?
No. It reads pasted text only and extracts comment blocks. It does not render, execute, fetch, crawl, upload, store, or log snippets.
What comments can it find?
It finds standard HTML comments wrapped in <!-- and -->, strips the wrappers, and lists the comment text with source-line context.
Why extract HTML comments separately?
Hidden comments often contain TODOs, migration notes, legacy warnings, or template labels that should be reviewed before publishing or moving markup.
