Automate Google Sheets + HubSpot
The database every team already has open. The CRM your pipeline reporting depends on. Put an agent between them and the hand-off stops being manual: it reads, decides, acts, and shows its work.
Report Assembler is a ready-made agent built around Google Sheets; point its last step at HubSpot to finish this hand-off.
Automations teams run
Unlike field-mapping automation, the step in the middle is an agent: it can summarise, classify, judge and draft, not merely copy values from Google Sheets into HubSpot.
When a row is added or edited in Google Sheets…
…an agent can create and enrich contacts in HubSpot — after reading the context and deciding it should.
When a sheet crosses a threshold in Google Sheets…
…an agent can update deals and notes in HubSpot — after reading the context and deciding it should.
When a schedule fires in Google Sheets…
…an agent can log activity in HubSpot — after reading the context and deciding it should.
When a contact or deal is created in HubSpot…
…an agent can append and update rows in Google Sheets — with the reasoning recorded in the run’s receipt.
When a stage changes in HubSpot…
…an agent can read ranges for reporting in Google Sheets — with the reasoning recorded in the run’s receipt.
When a form submits in HubSpot…
…an agent can maintain a rolling dashboard tab in Google Sheets — with the reasoning recorded in the run’s receipt.
Google Sheets to HubSpot, setup template
Start with the google-sheets-api node and a custom-api call to api.hubapi.com. Configure the Google Sheets source payload, the agent input, and the HubSpot operation. The sequential template does not implement conditional writes or approval by itself.
This is a schema-checked starting point, not an end-to-end tested automation. Replace every CONFIGURE_ value, choose the operations you intend, connect credentials and map source outputs into later inputs. An edge orders steps; it does not supply a condition, an approval gate or a field mapping. Add and test those controls explicitly before any write. Cloud APIs and model providers may receive data. Keep the workflow inactive until tested with fixtures.

}Configure Google Sheets New Row
Listen for new rows added to a specified Google Sheet and trigger the workflow when a new row is detected.
- spreadsheetId — The ID of the Google Spreadsheet to monitor Current example:
CONFIGURE_SPREADSHEETID. - sheetName — The name of the sheet within the spreadsheet to monitor Current example:
CONFIGURE_SHEETNAME.
Configure Custom API Request
This action node makes a custom API request to any endpoint with configurable method, headers, and authentication.
- url — The URL of the API endpoint Current example:
https://api.hubapi.com/crm/v3/objects/contacts. - method — The HTTP method for the request Current example:
GET. - authType — The type of authentication Current example:
None. - query — Query parameters for the request (e.g., 'key1=value1&key2=value2') Current example:
. - headers — Optional headers for the request. e.g., {"Content-Type": "application/json"} Current example:
{}.
Install Report Assembler
Report Assembler is a working agent built around Google Sheets. Install it, point its last step at HubSpot, and you have this hand-off without building it from an empty canvas.
Runs on your own machine · See what it does
What building this looks like
- Download AGNT Community Core — free and local-first.
- Connect Google Sheets with one OAuth sign-in and HubSpot with one OAuth sign-in; both land in the local vault.
- Start from a marketplace workflow, or drop google-sheets-api and a custom-api node onto the canvas with an agent between them.
- Put an approval gate on anything consequential, then run it — the receipt shows what was read in Google Sheets and what was written to HubSpot.
Google Sheets and HubSpot — common questions
Can I connect Google Sheets to HubSpot without writing code?
You can build it entirely from the canvas. Authorise Google Sheets with one OAuth sign-in, HubSpot with one OAuth sign-in, then tell the agent what land extracted data as clean rows should look like once HubSpot is involved. Code is an option for the unusual cases, never a requirement for the common ones.
How is this different from a field-mapping Google Sheets to HubSpot automation?
The difference shows up on the messy inputs. A rule chain needs every case enumerated in advance; an agent handles land extracted data as clean rows the way a colleague would — reading the Google Sheets context, judging it, then writing to HubSpot with the reasoning recorded.
Does my Google Sheets and HubSpot data leave my machine?
Not to us. AGNT runs locally and both sets of credentials are encrypted on your own disk. Outbound traffic goes only to Google Sheets, HubSpot and whichever model you chose — and pointing that at Ollama or LM Studio keeps everything on your hardware.
What does a Google Sheets and HubSpot run leave behind?
A receipt: what was read in Google Sheets, which tools ran with which arguments, what the agent concluded, and what it wrote to HubSpot. Anything consequential can sit behind an approval gate so a person signs off before it happens.
