In Excel, arrange the columns in exactly this order (no header row, one line per lead):
Store | URL | Country | Source | Contact | Phone | LinkedIn (contact) | LinkedIn (company) | Instagram | Score | Priority (High/Medium/Low) | Confidence | Tech Stack | Analytics Detected | Reason
All rows always enter as Sourcing, unassigned — then use the "Unassigned" tab to distribute them.
Select those cells in Excel, copy (Ctrl+C), and paste below (Ctrl+V).
