Number Validation

How to Filter 1 Lakh Active WhatsApp Numbers from Excel (.xlsx / .csv)

Key Takeaway: Master the process of uploading large Excel spreadsheets containing 1 Lakh to 5 Lakh phone numbers to extract active WhatsApp leads into filtered CSV files.

Many marketing agencies purchase large cold phone directories containing a mix of landlines, VoIP lines, and disconnected mobile numbers. Uploading these raw spreadsheets into a cloud validator allows you to scrub the list down to verified, active WhatsApp users before launching outreach.

Automated Phone Number Sanitization and Parsing

Raw Excel sheets often contain inconsistent formatting: parentheses, hyphens, leading plus signs, spaces, or international codes mixed with local formats. WAudience automatically strips non-numeric characters, parses international country codes (such as +91, +1, +44, +971), and deduplicates records in memory before initiating background validation.

Downloading Separate Active, Dead, and Breakdown Reports

Once the background worker completes processing, you can download targeted segmented outputs:

  • Active Leads CSV: Contains only verified WhatsApp numbers ready for campaign dispatch.
  • Smart VCF: Ready for direct phonebook import.
  • All CSV Breakdown: Complete audit trail showing the verification status of every uploaded line.

Frequently Asked Questions (FAQ)
