lead-extractor

A lead extractor combines several extraction patterns into one workflow — pulling names, email addresses, phone numbers, company affiliations, and (where present) job titles from messy text and outputting a structured CSV ready for CRM import. The ZTools Lead Extractor runs entirely in the browser, applies email + phone + name heuristics together, attempts to associate each contact item with the same person via proximity rules, and exports clean rows — saving hours of manual cleanup on conference attendee lists, email-thread participants, or contact-form scrapes.

Use cases​

Conference attendee list cleanup​

Public attendee directory pasted as messy text. Extract name + email + company per attendee into rows for CRM. Hours of manual data entry collapsed to seconds.

Email thread participant capture​

Long email reply chain. Extractor pulls each unique participant's name + email + signature info into one row per person.

LinkedIn / Twitter export normalisation​

Exported contact list with inconsistent formatting. Extractor standardises names + handles + company affiliations.

Sales prospect-list cleanup​

Bulk lead list from various sources. Extractor reformats into a single canonical structure for sales-tool import.

How it works​

  1. Paste source text — Conference list, email thread, contact form dump, exported directory. Mixed formatting OK.
  2. Run individual extractors — Email, phone, hashtag, name, and company patterns identified separately.
  3. Associate by proximity — Tokens within N characters / lines of each other associate as one lead. Configurable proximity window.
  4. Validate + dedupe — Drop incomplete rows (no email AND no phone), dedupe by email (lowercased).
  5. Export CSV — Columns: name, email, phone, company, title, source-context. Ready for CRM mapping.

Examples​

Input: "John Smith — VP Sales — Acme Corp — john@acme.com — (555) 123-4567"

Output: Single lead with all 5 fields populated.

Input: Email signatures from a thread

Output: One row per unique signer with as much data as the signature provided.

Input: Conference list with mixed formatting

Output: Each entry parsed independently; rows for each.

Frequently asked questions​

How accurate is the association?

Depends heavily on input format. Tabular / consistent formats: ~95%. Free-form text: ~70-85%. Always review the CSV before import; common errors are mismatched name/email pairs in dense text.

How are names recognised?

Heuristics: capitalisation pattern (Title Case), proximity to other lead fields, common first/last name lists. Foreign names are harder; review necessary.

Can I extract roles / titles?

Yes — recognised patterns ("CEO", "VP", "Director", "Manager", "Engineer"). Optional column.

Is the input uploaded?

No — entirely client-side. Important when handling personal data.

Does this comply with GDPR / CCPA?

Extraction itself is data processing. Storing or using extracted PII for marketing requires lawful basis (consent, legitimate interest, etc.). Tool output ≠ permission to email/call.

How do I improve accuracy?

Pre-clean the source — consistent line breaks, one entry per row. Tabular sources extract more cleanly than narrative paragraphs.

Tips​

  • Always review the CSV before CRM import — automated extraction misses edge cases.
  • Set proximity window based on input format. Tight (50 char) for tabular; wide (500 char) for free text.
  • Honour data-protection regulations. Extract only with lawful basis; store securely; delete on request.
  • For high-volume work, do extraction + manual spot-check rather than blind import.
  • Combine with email + phone validators before outreach — extracted data may be stale or mistyped.
