Google Sheets API: what you can do and how to use it with AI agents
The Google Sheets API lets you read and write values, create spreadsheets and tabs, apply formatting and run batch updates. It is one of the most used APIs for routine automation, from financial controls to lead databases. Access goes through the customer's Google Workspace account, with OAuth or a service account.
What the Google Sheets API offers
Reading and writing values
Read ranges and write data to cells, rows or columns.
Batch updates
Several changes in a single call, such as inserting rows, merging cells or adjusting formats.
Spreadsheets and tabs
Create new spreadsheets, and add, rename and delete tabs.
Formatting and validation
Number formats, colors, conditional formatting and data validation rules.
Charts and filters
Create charts, filters and pivot tables through configuration.
How to access the Google Sheets API
- With your company’s credentialsUses OAuth 2.0 with a Google Cloud project, to act as the user, or a service account with the spreadsheet shared with it.
- There are per-minute request quotas, so prefer batch updates.
- Use minimal scopes and share only the spreadsheets the agent needs.
- Spreadsheets with personal data fall under data-protection law such as GDPR: restrict who and what the agent can access.

What an iTeam agent does with the Google Sheets API
A tracker that fills itself
The agent logs each invoice, order or ticket that arrives by email into the tracking spreadsheet, with no manual typing.
Weekly close
Every Friday, the agent reads the sales tab, calculates the agreed metrics and sends the summary in Slack or WhatsApp.
Validating a received spreadsheet
When a partner sends a spreadsheet, the agent checks required columns and out-of-pattern values and returns the list of fixes.
Bridge between systems
The agent uses the spreadsheet as a review area: it pulls data from the ERP, someone approves line by line, and it writes the approved lines to the target system.
From the credential to the agent at work, with approval
Enable the API in Google Cloud
Create or use a Google Cloud project, enable the Sheets API and choose OAuth or a service account.
Share and store the credential
Share only the necessary spreadsheets with the account used and register the credential in the iTeam vault, defining read or write access per agent.
Test on a copy
Do the first test on a copy of the spreadsheet and enable writing on the original after checking the result.

Questions about the Google Sheets API
Is the Google Sheets API free?
Generally yes: API use is not charged separately, within Google Cloud quotas. There are usage limits, not a fee per call.
Do I need to write code to use the Google Sheets API with iTeam?
Not necessarily. Sheets is also in iTeam's app catalog, and the deployment team sets up which spreadsheets and tabs each agent uses.
Can the agent edit formulas?
It can write formulas into cells like any other value. The recommendation is to protect the calculation tabs and let the agent write only to the data tabs.
