Claude in Google Sheets: a natural place for your trained AI model

When asking Claude is enough

Suppose you have a sheet of customer messages and want to group them into Billing, Bug Report, and Account Access.

Asking Claude to categorize them can be a sensible starting point. You can explain the categories, inspect its suggestions, and refine the instructions. For exploratory work or a one-off task, that may be all you need.

The requirements change when that spreadsheet becomes a recurring business process.

Which category takes priority when a message mentions both a refund and a login problem? What separates a product defect from a feature request? Will next week’s rows follow the same rules as this week’s?

Those decisions belong to your business.

Train a model around the decisions your team makes

StayCharted AI Model Trainer learns from examples your team has labeled. Those examples teach it how you use each category, including distinctions that a category name alone cannot explain.

A support team might label refund requests as Billing even when the customer also mentions trouble signing in. A retail team might organize products using its own catalog taxonomy. A finance team might apply expense categories based on previously approved descriptions.

Instead of explaining those decisions again for each batch, you train a model and evaluate how well it reproduces them.

StayCharted tests the model on held-out examples, so you can see how it performs before relying on it. Predictions include confidence scores, which help you decide what needs human review. Confidence is a useful signal, not a guarantee that an answer is correct.

Corrections can become training examples for a future version. They do not silently change the model currently in use.

Coming soon: classification directly in Google Sheets

We’re preparing a StayCharted Google Sheets add-on so teams can classify rows directly in their spreadsheet. Google Workspace Marketplace review is pending.

The intended workflow is straightforward: choose the relevant columns, use your StayCharted model, and write categories and confidence scores back into the sheet.

For recurring work, that puts the model beside the data. A weekly export of support messages, a batch of product descriptions, or a list of invoice entries can follow the same classification process.

The add-on is coming soon. It will provide a direct way to use StayCharted from Sheets without requiring a Claude subscription.

How Claude and StayCharted could work together

StayCharted AI Model Trainer is already listed in Claude’s connector directory, so you can connect it today. Anthropic’s documentation says its Workspace sidebar can use connectors enabled in Claude. That creates a promising additional route into your trained models. See Claude’s Workspace documentation.

Add StayCharted to Claude, then try the Sheets sidebar

1. In Claude, open Settings → Connectors → Discover. Search for StayCharted, select StayCharted AI Model Trainer, and choose Connect.
2. Sign in to StayCharted and authorize the workspace you want to use. Follow the connector setup guide to enable assistant access to the relevant workspace and model.
3. With Anthropic’s Google Workspace add-on installed, open your spreadsheet and choose Extensions → Claude → Open Claude. Sign in to Claude, then look for and enable StayCharted in the sidebar’s connector menu, subject to your organization’s settings.
4. Try a small selection of rows with your trained model and check the returned categories, confidence scores, and where they are written before using it on a full sheet.

You can try this setup today, but we have not yet verified the complete workflow in the Sheets sidebar. A prompt to try is:

Use my Support ticket routing model to classify these messages. Put the category and confidence beside each row, then help me review the uncertain results.

In that workflow, StayCharted supplies the model’s predictions. Claude helps coordinate the task and work with the results in the spreadsheet.

This specific end-to-end workflow still needs validation in Claude’s new Sheets sidebar. Connector support alone does not establish that it works today.

More useful together

Bringing AI into spreadsheets reduces the effort of moving between tools. Bringing a trained model into that workflow adds a repeatable way to apply your team’s categories, with measured results and a process for review.

Claude can help you explore and organize the work. StayCharted can provide the classification model you have trained and checked.

Common questions about Claude, Google Sheets, and StayCharted

Is StayCharted’s Google Sheets add-on available now?

Not yet. Google Workspace Marketplace review is pending. It is coming soon and is intended to classify rows with your StayCharted model, then write categories and confidence scores into your sheet.

Can I use the StayCharted connector inside Claude’s Sheets sidebar?

You can add StayCharted AI Model Trainer from Claude’s connector directory today and try enabling it in the Sheets sidebar. Anthropic documents connector support there. The complete StayCharted classification workflow inside that sidebar has not yet been validated. See the current Claude connector setup guide for the existing integration.

How do I know whether my classification model is accurate enough?

Check its held-out evaluation results, including the categories it confuses, against your team’s requirements. Use confidence scores to help select predictions for human review, and evaluate on representative examples before relying on a recurring workflow.
