Claude Google Sheets Integration and Google Sheets Connector for Claude.
The Google Sheets Connector for Claude, by Lightbridge, is confidential spreadsheet automation designed to run inside your own cloud account and be driven by your own Claude. Lightbridge operates no part of it at runtime. Access is least-privilege, scoped to the sheets a workflow touches, and every change is logged. The connector is in closed beta.
Automate the spreadsheet without handing your data to a third party.
The usual way to put AI on a spreadsheet sends your cells to a shared, vendor-run service to work on them. That is fine for a scratch file and wrong for a finance model, a customer list, or anything under a confidentiality obligation. The value is real, and exposure is the price.
The Google Sheets Connector takes a different path. It is designed to run inside your own cloud account and is driven by your own Claude, so the work happens in your environment, under your access controls, with no outside operator in the loop.
Your cloud, your Claude, your controls.
The connector is designed to deploy into your own cloud account and run there. It authenticates to Google under least-privilege access scoped to the specific spreadsheets a workflow needs, stores those credentials encrypted under your own key, gates destructive writes behind an explicit confirmation, and writes an immutable audit record of every action. Lightbridge does not operate it for you.
Because your own Claude drives it, model use runs through your own Anthropic account. A large share of spreadsheet work is structural: sort, dedupe, aggregate, pivot, format. Claude handles that by writing the formula and letting Google Sheets compute the result, so the arithmetic stays in your sheet.
What Claude does on the sheet.
Formulas the sheet computes
Claude writes a live formula, from a single cell to a filled-down column, and Google Sheets evaluates it in place. The result is a working spreadsheet, computed by Google rather than pasted in.
Pivots and aggregation
Group, sum, and pivot with SUMIFS, COUNTIFS, and pivot tables written as spreadsheet operations. The arithmetic runs in Google Sheets, so totals are exact and auditable.
Exact dedupe and key joins
Deduplicate a column on an exact key, or join two ranges on a shared identifier with a lookup. These run as spreadsheet operations against the sheets you allow.
Structure and formatting
Create, clear, and reorganize tabs, apply conditional formatting, add data validation, and build charts. Multiple non-contiguous ranges update in a single call, keeping large changes fast and atomic.
Bulk row appends
Append single or batched rows built from a structural operation, so a sheet grows from a repeatable step rather than from copy-paste.
Session or schedule
The connector runs interactively in a Claude session or unattended on a schedule, so the same logic powers an ad-hoc task and a recurring report.
Confidential because it runs in your cloud, not ours.
The Google Sheets Connector is designed to run entirely in your own cloud account, so Lightbridge has no runtime access to your data or credentials. It uses least-privilege Google access scoped to exactly the spreadsheets the workflow needs, encrypted credential storage under your own key, confirm-gates on destructive writes, and an immutable audit trail. Your own Claude account covers model use.
For broader AI strategy and model selection the group practice is Lightbridge.ai, and for AI governance it is Lightbridge Automation. For the full technical detail behind this architecture, alongside the equivalent detail for the NetSuite extensions, see Product Security and Data Architecture.
The Lightbridge Software Google Sheets connector is in closed beta.
The Google Sheets Connector for Claude is in closed beta, as are all Lightbridge Software offerings. To learn about participation, contact us.
When the work touches other systems, the advisory sits with the group practice that owns it: Lightbridge Cloud for Salesforce, and Lightbridge ERP for NetSuite and ERP.
Google Sheets Connector for Claude: frequently asked questions
What is the Google Sheets Connector for Claude?
The Google Sheets Connector for Claude, by Lightbridge, is confidential spreadsheet automation designed to run inside your own cloud account and be driven by your own Claude. It writes formulas and pivots that Google Sheets evaluates in place, and reads only the spreadsheets a workflow needs, under access you control. It is in closed beta.
Is the connector in closed beta?
Yes. The Google Sheets Connector for Claude is in closed beta, as are all Lightbridge Software offerings. To discuss participation, contact us through the contact page.
What makes it confidential?
The connector is designed to run in your own cloud account, so your spreadsheet content and your Google credentials stay under your control. Your own Claude drives it, so model use stays inside your own Anthropic account. Much of the work is structural: Claude writes a formula and Google Sheets computes the result, which keeps the model out of the arithmetic.
Does Lightbridge run or see any of this?
The design keeps Lightbridge out of the data path. The connector runs in your own cloud account, and Lightbridge operates no part of it at runtime, so it has no route to your data, your credentials, or what Claude does on your sheets.
When does the AI read my values?
Your own Claude reads the ranges a task needs, and those reads go to your own Claude account, not to Lightbridge. For structural work such as sorting, aggregating, or pivoting, Claude directs the spreadsheet by writing a formula Google computes, so the model does not need the underlying values.
Whose Claude and whose cloud does it use?
Your own. The connector is driven by your Anthropic account, so Lightbridge never brokers or resells model access. It is designed around least-privilege Google access scoped to the specific spreadsheets in play, encrypted credential storage, confirm-gates on destructive writes, and an immutable audit trail.
Does it work with Excel or with databases?
This page describes the Google Sheets connector. If you want to ask about Excel, databases, or systems such as Salesforce and NetSuite, contact us. For Salesforce advisory the group practice is Lightbridge Cloud; for NetSuite and ERP it is Lightbridge ERP.
