I’ve got a batch of customer records sitting in Zoho CRM that no longer match the information in my CSV spreadsheets. Your task is to bring both sources into perfect sync. That means checking and correcting every contact detail, adding the most recent purchase history, and capturing all preferences or notes so nothing is missed. You can tackle the CSV files directly in Excel or import them first—whatever lets you work fastest—then mirror those edits inside Zoho CRM using its bulk-update or data import features. Consistent formats for emails, phone numbers, dates, and currency are essential, and any duplicates need to be merged so each customer ends up with a single, complete profile. At the end I’ll need: • The updated Zoho CRM database (live in the account I’ll share). • A refreshed CSV export that matches the CRM exactly. • A brief change log highlighting key fixes or issues found. If you’re comfortable with Zoho’s DataPrep, Excel Power Query, or similar cleanup tools, you’ll get this done smoothly—and quickly, which I’ll appreciate.
