Turn Google Sheets Rows Into HubSpot Contacts and Deals

How do you connect HubSpot to Google Sheets?

Connect HubSpot to Google Sheets by triggering on On New Row in a tracking sheet and having the flow call Get Contact by Email, then Create Contact and Create Deal in HubSpot, so every new row becomes a CRM record without anyone retyping it. FlowRunner is a visual AI-agent orchestration platform where automations run autonomously and pause for human judgment on the steps that carry real consequence. The same connection can run as a plain sync, or as an AI agent that reads each row, decides whether it matches an existing contact, and pauses for a person only when two records might be the same prospect.

The problem it solves

An ops lead or sales rep collects leads in a spreadsheet. A form export, a trade show list, a partner referral sheet, whatever the source, the rows sit there until someone opens HubSpot and manually creates a contact, a company, and a deal for each one. On a slow week that’s tedious. On a busy week, rows fall through the cracks: a prospect from Tuesday never gets a deal opened, a duplicate contact gets created because nobody checked if the email already existed, and the sales manager finds out three weeks later when the prospect emails asking why nobody followed up.

The spreadsheet itself isn’t the problem. It’s a reasonable place to collect leads from multiple sources. The problem is that nothing connects it to HubSpot, so every row requires a person to notice it, judge whether it’s a duplicate, and manually create three or four linked records in the right order. That’s not a job for a person; it’s a job that needs a system watching the sheet and a person available for the cases that actually require judgment.

How it works: the connection

The flow starts with a trigger on the sheet: On New Row fires the moment a row is added to the tracking tab, or On New or Updated Row if edits to existing rows should also kick off processing. FlowRunner loads the header row with Load Header Row so downstream steps can reference Email, Company, or Deal Value by column name instead of by position, which keeps the flow working even if someone reorders columns later.

Once a row lands, the flow calls Get Contact by Email against HubSpot to check whether the prospect already exists. If no match is found, it calls Create Contact, then Associate Objects to link the contact to the right company record, then Create Deal to open the opportunity in the inbound pipeline with the lifecycle stage set to Lead. The flow finishes by calling Update Row in Google Sheets to write the new HubSpot contact ID and deal stage back into the row, so the sheet stays an accurate mirror of what’s in the CRM rather than a stale export.

Can an AI agent run it? (and why a human stays in the loop)

Yes, and this is where it stops being a sync tool. A plain trigger-to-action wire will call Create Contact every time a row arrives, whether or not that prospect already exists under a slightly different email or a shared company domain. An AI agent reads the row, calls Get Contact by Email and Get Contacts at Company as tools, and reasons about what it finds before deciding what to do next.

Here’s the decision moment. The agent finds a row for a prospect at “acme-corp.com” and, checking associations, finds two existing contacts at the same company domain with similar names, one created six months ago as “acme.co” and one as “acme-corp.com.” Nothing in the row data settles which one is right. Instead of guessing, the agent invokes a human-in-loop flow as a callable tool. It posts to the CRM admin’s Slack channel: “I found two contacts that could match this row: a lead from March under ‘acme.co’ and one from May under ‘acme-corp.com’. Which should this deal associate with, or is this a new contact?” The admin picks one with a click. The agent associates the deal accordingly, writes the decision and the admin’s identity into the audit trail, and resumes the rest of the flow.

This is not a sync tool. The agent knows when to stop and ask. Every other row, the vast majority, that has a clean unambiguous email match or a clear non-match, processes automatically with no one touching it.

FlowRunner vs Zapier

Zapier does this connection well for the simple case. Its HubSpot and Google Sheets triggers are mature, the setup takes minutes, and for a team that just wants “new row creates a contact” with no branching logic, it’s a reasonable choice.

Where it runs out of road is the duplicate case and the audit trail. A Zap either creates the contact regardless of whether one already exists, or it needs a separate Filter and Lookup step chain that still can’t reason about ambiguous matches, it can only apply a hard rule.

Capability	FlowRunner	Zapier
Human-in-the-loop on ambiguous matches	Native: the agent invokes a Slack approval as a callable tool and logs the decision	Not available; duplicates either get created or require manual rule-based filters
Users included	Unlimited on every tier	Priced per user on team plans
AI provider	BYOK: connect your own key from your preferred provider	Requires Zapier’s own AI credits or a separate integration
Self-hosting	Available on Enterprise, with full audit retention	Not available
Pricing model	Transparent workflow-based execution tiers	Per-task pricing that scales with every row processed

Before and after

Metric	Before	After
Time to create a lead in HubSpot	A rep manually creates the contact, company, and deal from the spreadsheet row	Contact created, associated, and deal opened from the row automatically
Duplicate contacts	No systematic check before creating a new record	Get Contact by Email runs before every create, and ambiguous matches route to a human
Sheet accuracy	The sheet is a static export that goes stale the moment HubSpot changes	Update Row writes the HubSpot contact ID and deal stage back after every run
Stalled deal visibility	Deal stages update only when a rep remembers to touch HubSpot	Deal stage sync runs from downstream activity without manual entry
CRM admin time on cleanup	Admin discovers duplicate or orphaned records weeks later during a data audit	Admin resolves flagged duplicates in Slack at the moment they’re created

What you can build

Leads tracker to CRM pipeline. A new row in a shared leads sheet triggers Get Contact by Email, then Create Contact, Associate Objects, and Create Deal, with the sheet updated to show the deal stage as it moves.

Trade show list import. Import from CSV loads a batch of trade show contacts into a sheet, and the agent processes each row through the same lookup-and-create logic, flagging any rows missing a required email for a person to fill in.

Deal stage export for the sales meeting. On a weekly schedule, Get All Deals pulls current pipeline data from HubSpot, Add Rows writes it into a report sheet, and Export Sheet generates a PDF that’s emailed to the team before the Monday pipeline review.

Row validation before it reaches HubSpot. Rows that fail validation, a missing company name or an unrecognized lifecycle stage, are held and routed to the sheet owner via Slack instead of creating a malformed HubSpot record.

Common questions

Is it free to connect HubSpot and Google Sheets on FlowRunner? Yes. FlowRunner gives new accounts a $100 credit on the Growth tier, which covers roughly 67 days of real usage with no credit card required, and both HubSpot and Google Sheets are included connectors on every paid tier.

Can I self-host this HubSpot and Google Sheets flow? Yes, on the Enterprise tier. Self-hosting gives you a single-instance or multi-instance deployment with the same HubSpot and Google Sheets connectors, plus full audit retention and compliance reporting.

Does the agent need my own OpenAI key? FlowRunner uses a BYOK (Bring Your Own Keys) model, so you connect your own key from your preferred AI provider and the agent runs against it directly.

What happens when the agent isn’t sure which HubSpot contact to use? The agent stops before creating a duplicate. It sends a Slack message to a CRM admin describing the conflicting records it found, and it waits for a decision before associating the deal to either contact.

Does this work without an AI agent, as a plain sync? Yes. You can wire On New Row in Google Sheets directly to Create Contact and Create Deal in HubSpot as a standard trigger-to-action flow with no agent reasoning involved, then add the agent layer later when you want it handling exceptions.

How is this different from Zapier’s HubSpot and Google Sheets integration? Zapier can move the row into HubSpot on a trigger, but a duplicate contact either gets created twice or the zap fails silently; FlowRunner’s agent evaluates the match itself and routes only the ambiguous cases to a person, with the decision logged in an audit trail.

Getting started

Start with the $100 credit on the Growth tier, roughly 67 days of real usage, no credit card required. Connect your HubSpot integration and your Google Sheets integration, pick On New Row as your trigger, and turn on the flow.
