Extract Script Sources
Extract script src values from pasted HTML, templates, tag snippets, and copied page fragments.
0 / 30,000 characters. No upload, storage, or account required.
Common script source extraction workflows
Use script source extraction when external JavaScript URLs are buried inside pasted HTML and you need a safe local inventory.
Format first
Use HTML Formatter before extraction when copied script tags are compressed into one long line.
Parse script URLs
Use URL Parser after extraction to inspect hosts, paths, and query parameters without loading the scripts.
Compare with links
Use Extract HTML Links and Extract HTML Image Sources for a fuller HTML asset review.
What this tool does
Extract Script Sources finds external script src values in pasted script tags, removes duplicates, shows source-line context, and runs locally in your browser without loading scripts.
Common use cases
Extract external script src values from pasted HTML, analytics snippets, tag-manager notes, templates, and copied page fragments before dependency QA or documentation.
Use Extract Script Sources 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 snippets, tag-manager notes, templates, or copied script tags that contain src attributes.
- Choose whether duplicate script URLs should be removed and whether encoded ampersands should be normalized.
- Review the extracted script source list and source lines, then copy the clean output for QA or documentation.
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
Script source extraction runs locally in your browser. ClearUtils does not upload, store, fetch, execute, crawl, or log the HTML text or script URLs you paste.
FAQ
Does Extract Script Sources execute scripts?
No. It only reads pasted text and extracts visible script src values. It does not load, execute, fetch, crawl, upload, or store scripts.
What script formats are supported?
It finds common script tags with src values in double quotes, single quotes, or unquoted attributes inside pasted HTML snippets.
Can it detect inline JavaScript?
No. This tool extracts external script src URLs only, which keeps the output focused on dependency and asset inventory workflows.
