How to Connect Claude to Smartsheet (No Official Connector)
No — there’s no official Claude connector for Smartsheet. It isn’t in Anthropic’s Connectors Directory, so Claude can’t open your sheets, read a project grid, or update a row on its own. You can paste rows into a chat, but there’s no live link between Claude and your Smartsheet workspace.
That’s the gap most ops teams hit. But you don’t have to live inside a chat window: Smartsheet has a REST API (API v2), and any AI agent that lets you bring your own API key can use it. Here’s why the connector doesn’t exist, and how to wire Smartsheet into an agent that keeps your grids current while you’re in meetings.
Why there’s no Smartsheet connector
Anthropic’s connector catalog covers a fixed set of first-party apps — Gmail, Google Drive, Slack, and a handful of the biggest horizontal tools. Smartsheet is a work-management and grid-database hybrid used heavily by project managers and ops teams, but it isn’t on that list, and Anthropic hasn’t shipped one.
So teams running projects in Smartsheet end up in one of two places:
- Claude’s connectors can’t reach Smartsheet at all. Anything you want Claude to “see” has to be copied into the conversation by hand.
- No-code automation tools do list Smartsheet, and they’re fine for basic field-mapping triggers — “new row → post to Slack.” But they don’t reason over your project data or decide what to change; they just move fields between apps on a fixed rule.
What both approaches miss: Smartsheet already exposes a full REST API with bearer-token authentication. Your sheets, rows, columns, and attachments are all reachable programmatically — you just need an agent that will talk to the API with your own token.
Bring your own API key: the bridge to Smartsheet
Carly connects to 200+ tools out of the box, and it adds the piece the connector directories skip: it lets you bring your own API key to reach anything with a REST API. Smartsheet has one, so that’s the whole bridge.
You generate an API access token inside Smartsheet, give it to Carly, and Carly can then read and write your sheets as a step in a real workflow — the same way it works with a natively supported app. There’s no connector to wait for and no data to paste.
And because Carly runs in the cloud on triggers, this isn’t “answer me when I ask.” It’s Smartsheet upkeep that happens on its own — a row updated, a status email sent, a task assigned — while your laptop is closed.
What you can automate once it’s connected
With Smartsheet reachable through its API, an agent can handle the grid maintenance and status-chasing that eats a project manager’s day:
- Update rows automatically — when a task email arrives or a status changes upstream, set the cell, flip the status column, and stamp the date without anyone touching the sheet.
- Add new rows from inbound — a request lands in your inbox and the intake sheet gets a new row with the requester, date, and priority filled in.
- Chase status and report out — read the project sheet, find rows past their due date, and send an owner-by-owner nudge or a rolled-up summary email.
- Answer questions against live data — “what’s blocked on the launch sheet and who owns it?” answered from the current grid, not a stale export.
- Tie it to the rest of your stack — since the same agent handles email, calendar, and tasks, updating Smartsheet becomes one step in a workflow instead of a standalone chore.
How to connect Smartsheet to Carly
- In Smartsheet, generate an API access token (under Personal Settings → API Access → Generate new access token). Copy it — you only see it once.
- Paste your API token into Carly on the integrations page.
- Describe the workflow you want in plain English — “when a client emails a change request, add a row to the intake sheet and email me the summary” — and Carly interviews you, then builds it.
Your token stays yours: you can revoke or regenerate it in Smartsheet at any time.
Claude connector vs. no-code tools vs. Carly
| Claude | No-code tools | Carly | |
|---|---|---|---|
| Official Smartsheet connector | No | Basic triggers | Via your API key |
| Reads & writes sheet data | No | Limited field mapping | Yes |
| Acts on triggers / events | No | Basic triggers | Yes, 24/7 in the cloud |
| Reasons over your project grid | In chat only, if you paste rows | No | Yes |
| Sends email as part of the flow | Draft-only | No | Yes (Gmail + Outlook) |
| Works while your laptop is closed | No | Yes | Yes |
Claude is a strong assistant inside a chat — but with no Smartsheet connector, it can’t see your grid unless you paste rows in. No-code tools can shuttle a row between apps on a fixed trigger, but they won’t reason over the project or decide what to update. Carly reaches Smartsheet through your own token and acts on it as part of a workflow that runs on its own.
Frequently Asked Questions
Does Claude integrate with Smartsheet?
Not directly. Smartsheet isn’t in Anthropic’s Connectors Directory, so Claude can’t read or write your sheets on its own. You can paste rows into a chat and have Claude reason over them, but there’s no live connection. To connect Smartsheet to an AI agent, you need a tool that supports its REST API — like Carly, which connects via your own API key.
Does Smartsheet have an API?
Yes. Smartsheet exposes a RESTful API (API v2) with bearer-token authentication that supports reading and writing sheets, rows, columns, and attachments. You generate an API access token from your Smartsheet personal settings.
Can I connect Smartsheet to an AI agent?
Yes. Because Smartsheet has a REST API, any agent that lets you bring your own API key can read and write your sheet data. Carly does this — you generate a token in Smartsheet, add it to Carly, and it can then update rows, add intake records, and send status reports automatically.
What can an AI agent actually do in Smartsheet?
Update rows and status columns, add rows from inbound email, chase overdue tasks, roll up a project into a status email, and answer questions against the live grid — all triggered by events like an email arriving or a due date passing, rather than you prompting in a chat.
How much does this cost?
Carly’s AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited. Your Smartsheet API access is part of your existing Smartsheet plan.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
