How to connect Google Sheets to ChatGPT

Porter’s Google Sheets connector for ChatGPT takes 3 steps and no code. Connect your tabs in Porter, add Porter’s MCP URL to ChatGPT as a custom MCP server, then ask about any tab as data. For more screenshots, see Porter’s guide on how to connect Google Sheets to ChatGPT. MCP (Model Context Protocol) is the open standard ChatGPT uses to connect to tools such as Porter.

Before you start

You need a Google account that can open the spreadsheet, as well as a free Porter account and a ChatGPT plan that supports custom MCP servers. Each tab needs its headers in row 1, plus a Date column if you want date filters.
Custom MCP servers are in beta in ChatGPT on the web, so set up Porter and ask your questions from a browser. On Business, Enterprise or Edu, an admin or owner turns on developer mode; on Pro, you turn on developer mode yourself (OpenAI’s guide to custom MCP apps).
Works in ChatGPT on the web (chatgpt.com, custom MCP servers in beta) and in Codex, with the same Porter MCP URL.

Step 1: Connect Google Sheets in Porter, then pick tabs
Sign up to Porter with Google and pick Google Sheets as the source. Choose the spreadsheet and tick the tabs ChatGPT should read, then pick ChatGPT as the destination. Each tab becomes one data source (a spreadsheet on its own gives ChatGPT no columns to read).
Step 2: Add the Google Sheets connector to ChatGPT
In ChatGPT, open Customize › Plugins, click Add and choose Add custom MCP server. On Business, an admin does this from Workspace settings › Apps › Create. Name it Porter Metrics, paste this URL as the Server URL and keep OAuth as the authentication:
MCP URL
https://mcp.portermetrics.com/mcp
Tick “I understand and want to continue”, then select Create as a plugin.
Step 3: Ask ChatGPT about Google Sheets
Next, select Continue to Porter Metrics, sign in to Porter and click Allow Access. Then select Try in chat and paste this prompt:
Prompt
List the tabs in my 'Marketing 2026' spreadsheet with their row counts, then summarize the 'Leads' tab by week for the last 4 weeks.

02Use cases and prompts

What you can ask ChatGPT

Each use case comes with a prompt to copy, the fields it uses and who it’s for. Field IDs come from your own header row, so these headers are just examples; the Google Sheets fields list explains the naming.

Can ChatGPT pace the budgets in my sheet against live ad spend?

The problemBudgets sit in a tab while spend gets pasted in from the ad platforms on Monday, and by Thursday the pacing column is already wrong.

What ChatGPT doesChatGPT reads your Budgets tab together with live spend for the same campaigns. That spend comes from the Google Ads connector for ChatGPT and the Meta Ads connector for ChatGPT. It then projects month-end spend from the daily run rate and flags campaigns heading over budget.

What you getThe Monday paste goes away, and you can pull budget from a campaign mid-month instead of explaining the overspend afterwards.

Prompt

Read the 'Budgets' tab (Campaign, Monthly budget). Next to it, show month-to-date Blended Ad Spend for the same campaigns from Google Ads and Meta. Project month-end spend from the daily run rate and list campaigns that will pass 100% of budget, most urgent first.

For: in-house PPC managers · agency media buyers · marketing leads

Fields used: CampaignMonthly budgetBlended Ad SpendCampaign name

Can ChatGPT summarize a leads log in Google Sheets by week?

The problemEvery lead lands in a shared tab, but the Monday pivot table that would make sense of it never gets built.

What ChatGPT doesChatGPT groups the rows by week and Source, then counts leads, adds up deal value and names the source that grew or dropped the most.

What you getYou see which channel to fund next week before anyone builds a pivot table.

Prompt

In the 'Leads' tab, for the last 8 weeks, count rows and sum Deal value by Week and Source. Which Source grew or dropped the most against the previous 4 weeks?

For: B2B marketers · CRM managers · agencies reporting leads

Fields used: DateSourceStatusDeal value

Can ChatGPT find the right tab and read a range without any setup?

The problemA spreadsheet full of tabs called “Copy of Q3 final v2”, but the one that matters is never the first one you open.

What ChatGPT doesWith no setup, ChatGPT lists every tab with its row and column counts, then reads the A1 range you name straight from the Sheets API. Values come back as the sheet displays them, and ChatGPT reads the formulas instead when you ask (Google’s values.get reference for render options).

What you getYou land on the live tab and its totals in one answer, instead of clicking through a spreadsheet you inherited.

Prompt

List every tab in the 'Client Reporting' spreadsheet with its row and column count. Then read 'Summary'!A1:H40 and tell me which rows hold totals.

For: marketing ops · agency account managers

Fields used: ChatGPT reads the range directly (sheet_list, values_get)

Can ChatGPT compare a targets tab with an actuals tab in Google Sheets?

The problemTargets sit in one tab and actuals in another, so the monthly review opens with an hour of VLOOKUPs.

What ChatGPT doesChatGPT lines up each month and KPI across both tabs, then returns the gap and the percent to target.

What you getThe review starts with the KPIs that slipped twice instead of fixing lookup formulas.

Prompt

Compare the 'Targets' tab with the 'Actuals' tab by Month and KPI for 2026. Show Target, Actual, the difference and percent to target, and flag any KPI below 90% for two months in a row.

For: marketing leads · founders · marketing analysts

Fields used: MonthKPITargetActual

Can ChatGPT roll up one tab per client into one scorecard?

The problemEvery client has a tab with the same columns, but the Friday roll-up is an hour of copy-paste into a summary tab.

What ChatGPT doesChatGPT pulls the client tabs together and returns one row per client with spend, leads, cost per lead and the change from the week before. Each tab is its own data source in Porter, so keep the same headers on every client tab.

What you getFriday’s status note starts with the clients whose cost per lead moved instead of a copy-paste session.

Prompt

For the tabs 'Client A', 'Client B' and 'Client C', show last week's Spend, Leads and Spend divided by Leads per tab, next to the week before. Mark any client whose cost per lead rose more than 20%.

For: agency account managers · agency owners

Fields used: DateSpendLeads

Can ChatGPT check a tab for blanks, duplicates and typos before a report goes out?

The problemOne blank date or a “1,200” typed as text, and the client dashboard built on that tab breaks an hour before the call.

What ChatGPT doesChatGPT reads the range, then lists empty required cells, duplicate rows and values that don’t fit their column, with row numbers, so you know exactly which cells to fix in Sheets.

What you getYou catch the broken rows before the client does, without filtering every column by hand.

Prompt

Read 'Orders'!A1:L2000. List rows where Date or Order ID is empty, rows that appear twice, and cells in the Revenue column that aren't numbers. Give me the row numbers.

For: marketing ops · marketing analysts · agencies

Fields used: ChatGPT reads the range directly

Can ChatGPT compare this week with last week in any dated tab?

The problemWeek over week in a sheet means two SUMIFS per metric and a helper column just to find the week.

What ChatGPT doesOn any dated tab, ChatGPT filters the tab by date, then compares the two weeks for every number column and names the biggest movers.

What you getThe weekly check becomes one question you can ask any morning, on any tab with a Date column.

Prompt

In the 'Sales' tab, compare the last 7 days with the 7 days before for every number column. Show both totals, the change and the percent change, largest first.

For: e-commerce marketers · founders · agencies

Fields used: DateSalesOrders

03Why Porter

Why Porter for Google Sheets in ChatGPT

Porter reads your tabs as data across spreadsheets and sets them next to live ad spend. To build an agent that edits cells, follow Google’s guide to the official Sheets MCP server. You can run both.

✓

Every tab as data

Each header becomes a field, number columns become metrics and a Date column turns on date filters, so ChatGPT asks across tabs and spreadsheets in one answer.

⊞

Google Sheets next to your ad spend

Set budgets, targets or offline sales against live Google Ads, Meta and GA4 numbers from all ChatGPT connectors in one answer, then have ChatGPT turn it into a chart.

⚙

Safe for live spreadsheets

ChatGPT reads every tab and range you connect, then tells you what to fix, while your spreadsheets stay exactly as you set them. You pick the tabs and revoke access anytime.

One URL, nothing to host

Connect Sheets in Porter and add one MCP URL to ChatGPT on the web. There’s no Google Cloud project to set up.

↻

One connection, every destination

The same connection also feeds Google Sheets to Looker Studio and Google Sheets to BigQuery, so the tab behind ChatGPT’s answer also fills your reports. The same MCP URL also works in Claude.

✓

Live dashboards, not only chat answers

Ask ChatGPT for a dashboard and Porter’s AI dashboards publish it at its own link, synced automatically and ready to share. Official MCP servers answer inside the chat and stop there.

06Data and actions

Google Sheets data ChatGPT can use

The Google Sheets connector builds ChatGPT's field list from your own tabs: every column is a field, named from its header row. Number columns become metrics while text and date columns become dimensions, and a Date column turns on date filters. ChatGPT can also list a spreadsheet's tabs and read any range (full list of Google Sheets fields).

Tabs read cleanly when row 1 has one header per column, each row is one record, and dates sit in a single Date column. Numbers typed as text, like "1,200" with a stray space, come in as text rather than as a metric ChatGPT can add up. Rename a header only when you're ready to update the prompts that use it.

How ChatGPT reads Google Sheets

Behavior	What it means	Example
Header row → field names	Each header becomes a field with the `sheets_source_` prefix	Ad spend → `sheets_source_ad_spend`
Number columns → metrics	ChatGPT can add, average and compare them	Spend, Leads, Revenue
Text columns → dimensions	ChatGPT groups and filters by them	Campaign, Source, Client
Date column → date filters	Rows filter by any date range	Last 7 days, by Week
One tab = one data source	Ask across several tabs in one question	Client A, Client B, Client C
Range reads	Any A1 range, straight from the Sheets API (Google's guide to A1 notation and ranges)	'Summary'!A1:H40
Tab list	Every tab with its row and column count	20 tabs in a shared file
Spreadsheet search	Find a spreadsheet in Drive by name	"Marketing 2026"

07Security

Is it safe?

Yes. Porter's Google Sheets connector for ChatGPT reads through your Google sign-in, and your spreadsheets stay exactly as you set them, from every cell to every sharing setting. Disconnect in Porter, or remove an app's access to your Google Account, at any time.

What ChatGPT can see in Google Sheets

ChatGPT sees only the tabs you connected in Porter, from spreadsheets the connecting Google account can open. A tab that account can't read publishes no fields, so nothing from it reaches ChatGPT (Porter's privacy policy).

Prompt injection in shared sheets

Text typed into a cell is data rather than an instruction ChatGPT should follow. Google warns about indirect prompt injection for its own Sheets MCP. Porter's connection reads and never writes, so your spreadsheet stays as you set it even if a cell holds a planted instruction.

08FAQ

FAQ

Most questions cover Claude, freshness, several tabs, API keys and sending data the other way. Then come 3 fixes: tabs ChatGPT can't see, numbers that don't match, and slow or cut-off answers.

Can I use Porter in Claude too?

Yes. Porter's MCP URL, the same one behind the Google Sheets connector for ChatGPT, also works in Claude as a custom connector, with the same Porter account and tabs. See Porter's Google Sheets connector for Claude for the Claude setup and what it covers.

How fresh is the data, and what if I add a column?

Range reads come from the Sheets API the moment ChatGPT asks, so they show the sheet as it is. For a new column, ingest the tab again in Porter. Until then, ChatGPT reads the new column through a range.

Can I connect several spreadsheets or client tabs?

Yes. Every tab you connect in Porter becomes its own data source, from any number of spreadsheets. ChatGPT can then ask across them in one question. Agencies usually connect one tab per client with matching headers, then ask for one scorecard.

Do I need an OpenAI API key?

No. The Google Sheets connector for ChatGPT is a custom MCP server you add with one URL. So there's no OpenAI API key to paste into a spreadsheet and no code to run. If you're coding your own agent, point it at Google's official Sheets MCP instead.

Can Porter send ad data into Sheets instead?

Yes. Porter also works the other way: it can send marketing data into Google Sheets and keep a tab updated on a schedule. That's a separate setup, but both can run on the same spreadsheet.

Troubleshooting

Why can't ChatGPT see my tab or its columns?

Connect the tab itself in Porter, not just the spreadsheet, and keep its headers in row 1. The connecting Google account must also be able to open the file. A tab nobody has ingested has no fields yet, but ChatGPT can still read its range.

Why don't the numbers match my sheet?

ChatGPT's numbers through Porter can differ from your sheet for 5 usual reasons. For example, dates come back as text like 20261011, numbers as text like 73.0, and a renamed header breaks the old field name. Rows past the row limit are also left out, while a tab without a Date column can't be filtered by date.

Why is a big question slow or cut off?

Porter returns up to 1,000 rows per question by default, then flags anything longer as truncated. Google also caps reads at 60 per minute per user and times out requests after 180 seconds (Google's Sheets API usage limits). Instead, ask by month, or name a smaller range.
