Automate Google Sheets + Trello
The database every team already has open. Boards and cards — simple enough to automate deeply. 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 Trello 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 Trello.
When a row is added or edited in Google Sheets…
…an agent can create and move cards in Trello — after reading the context and deciding it should.
When a sheet crosses a threshold in Google Sheets…
…an agent can update checklists and labels in Trello — after reading the context and deciding it should.
When a schedule fires in Google Sheets…
…an agent can summarise a board in Trello — after reading the context and deciding it should.
When a card is created or moved in Trello…
…an agent can append and update rows in Google Sheets — with the reasoning recorded in the run’s receipt.
When a due date approaches in Trello…
…an agent can read ranges for reporting in Google Sheets — with the reasoning recorded in the run’s receipt.
When a checklist completes in Trello…
…an agent can maintain a rolling dashboard tab in Google Sheets — with the reasoning recorded in the run’s receipt.
Google Sheets to Trello, setup template
Start with the google-sheets-api node and a custom-api call to api.trello.com. Configure the Google Sheets source payload, the agent input, and the Trello 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.trello.com/1/cards?key={key}&token={token}. - 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 Trello, and you have this hand-off without building it from an empty canvas.
Runs on your own machine · See what it does
Wiring Google Sheets to Trello
- Get AGNT Community Core. Free, local, no sign-up needed to run a workflow.
- Add both connections to the vault — Google Sheets takes one OAuth sign-in, Trello takes an API key pasted into the vault.
- Configure the nodes above, or start from a marketplace workflow and edit it. The agent in the middle is the part worth spending time on.
- Run it once with an approval gate in place. The receipt tells you what it read, what it concluded, and what it changed in Trello.
Google Sheets and Trello — common questions
Can I connect Google Sheets to Trello without writing code?
No code is required. Add both connections in the vault (Google Sheets uses one OAuth sign-in, Trello uses an API key pasted into the vault), then either install a marketplace workflow for this pair or drag the two nodes onto the canvas and put an agent between them.
How is this different from a field-mapping Google Sheets to Trello automation?
A field mapping copies values and breaks on the first record nobody anticipated. The middle step here reads the Google Sheets item in full and decides — whether it matters, how to summarise it, and what belongs in Trello. Deciding to do nothing is a valid outcome, which no mapping can express.
Does my Google Sheets and Trello data leave my machine?
Your credentials stay in a vault on your own disk rather than in someone else’s cloud. The only calls made are the ones the workflow needs: Google Sheets, Trello, and your chosen model provider — which can be a local one.
What does a Google Sheets and Trello 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 Trello. Anything consequential can sit behind an approval gate so a person signs off before it happens.
