Sync new leads from a spreadsheet into HubSpot automatically

Imports leads from a spreadsheet into HubSpot as contacts, updating existing records instead of creating duplicates.

How the work actually flows

It branches. Exactly one path is taken; runs once per one per lead row.

The problem it solves

When leads come in through a form or landing page that dumps into a spreadsheet, someone has to manually copy each one into your CRM. That's slow, and it's easy to create duplicate contacts or miss a lead entirely.

Who it fits

Sales and marketing teams collecting leads outside their CRM.

How it works

  1. You run the sync whenever new leads are ready to import
  2. It reads the contact rows from your spreadsheet
  3. Each lead is matched against HubSpot by email address
  4. Matching contacts are updated and new ones are created in HubSpot
What you get

HubSpot records that always match your sheet

Your new leads land in HubSpot as clean, up-to-date contacts, automatically matched to existing records so nothing gets duplicated.

What you get

An up-to-date HubSpot contact list with no duplicate entries.

What you need

A Google Sheets account and a HubSpot account with API access.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
