What this tool does

Semantic Version Extractor extracts semantic versions from pasted text, logs, CSV exports, copied HTML, support tickets, Markdown notes, and uploaded local text files. The parser runs entirely in the browser, then produces a deduplicated audit table with line numbers, normalized values, validity, and reasons. It is built for practical cleanup work where a teammate needs a list that can be checked, copied, downloaded, and pasted into a real workflow without sending source text to a server. Turn messy notes, exports, logs, tickets, and copied web pages into a clean review list. You can keep unique rows only, preserve invalid rows for review, sort the normalized output, switch between CSV, JSON, Markdown, SQL IN, TypeScript union, and plain lines, then download the exact artifact you need. Sensitive profiles such as cards and JWTs mask values in the output while still giving you useful validation signals.

How Semantic Version Extractor fits into your work

Use it before upload, handoff, archive, support review, or any moment where a file needs one local check before it leaves your machine.

File jobs

  • Checking file type, size, metadata, and obvious mismatch signals before sharing.
  • Preparing mixed folders for upload, archive, intake, or review.
  • Keeping sensitive files in the browser instead of sending them to an account-based service.

File checks

  • Do not treat the extension alone as proof of the real file type.
  • Review metadata before a file goes to customers, vendors, or a public page.
  • Keep the original file until the copied, converted, or exported result is verified.

Real-world use cases

  • Clean semantic versions before import

    Paste exports or support notes, dedupe and sort the list, then export CSV for a CRM, ticket system, or script.

  • Review logs and copied pages

    Extract semantic versions from logs, HTML, Markdown, or pasted web pages while keeping source line numbers and validation reasons.

  • Generate developer-ready snippets

    Send the clean list straight to JSON, SQL IN, or a TypeScript union without hand-adding quotes and commas.

Common pitfalls

  • Do not treat semver validation as proof that the account, domain, or resource really exists.

  • Copied web text often includes hidden whitespace, so normalize before deduplicating or importing.

  • When you need an audit trail, download CSV or Markdown with line numbers instead of copying only the final list.

Privacy

All parsing, validation, normalization, deduplication, copy, and download actions run in the browser. Uploaded text files are read locally with the File API and are not sent to Toolora servers. Be careful when copying or downloading output that contains customer data, access tokens, or internal identifiers.
