How to Connect Smartproxy to Google Sheets (4 Methods Compared)

The Problem With Getting Sheet Data In and Out of Smartproxy

You have a Google Sheet full of target countries, project configs, or infrastructure tables — and you need Smartproxy endpoint strings generated for each row, or you need the full catalog of available Smartproxy hostnames pulled back into the sheet so your team can plan against it.

Smartproxy is good at providing residential, datacenter, ISP, and mobile proxy endpoints with global location targeting. But the gap between your spreadsheet and those endpoints is usually bridged by someone writing a script. The default flow is: open the Smartproxy dashboard, manually look up endpoint formats, write connection strings by hand, copy them into the sheet row by row.

Below are the four ways teams handle this. Only the last one scales.

Method 1: Manual Copy-Paste

The default workflow starts in the Smartproxy dashboard. You find the endpoint generator, pick a proxy type, select a country, copy the formatted connection string, switch back to the sheet, and paste it into the right row. Then you do it again for the next country.

For fifteen target countries, that's fifteen round trips between the dashboard and the sheet. Each one requires re-selecting the session type, confirming the credential format is right, and making sure the port matches the proxy type. If you're generating both rotating and sticky variants for each country, the number doubles.

The specific grind here is the credential embedding. Smartproxy endpoint strings follow a strict format — username, password, host, and port all concatenated in a specific pattern. One typo anywhere in the string breaks the connection silently. You don't find out until a scraping job fails at 2 AM. By that point you're diffing strings character by character.

Method 2: Zapier or Make

Both platforms have Smartproxy connector options, and you can wire up an automation that reads rows from the sheet, calls an API to retrieve or construct endpoint data, and writes the results back.

Before you read further — a few honest questions. Do you know what a REST API connector is? Have you built field mappings before? Do you know the difference between a trigger and an action in an automation tool? If those terms feel unfamiliar, skip ahead to Method 3 or 4. This path will cost you a weekend and a customer support ticket.

For those who are still reading: the setup involves authenticating to a Smartproxy API, identifying the right endpoint catalog call, mapping each response field to the right column in your sheet, and handling the credential injection into the output string format. The automation works once it's built.

But a row-by-row trigger is not the same as a bulk generation run.

Sending fifteen country codes through a Zap means fifteen separate trigger fires. If one country returns an unexpected format, row 8 fails silently and the rest continue without you knowing row 8 is wrong.

You probably just need the endpoint strings written into your sheet and have no idea how to wire up an API connector — and you shouldn't have to. So this gets pushed to whoever on your team builds automations, and now you're waiting on a Slack reply from someone who has four other things queued ahead of your proxy table.

And once you need to join endpoint data against a second tab — matching project names to credentials, for instance — you've left Zapier's native field-mapping capabilities behind entirely.

Method 3: The Previous Generation — Connector Add-Ons

Until recently, the best option for repeatable spreadsheet ↔ API workflows was a category of add-ons that let you configure column mappings and run saved templates. You set your source range, tagged your output fields, saved the config, and ran it on demand.

That was a genuine improvement over manual copy-paste. The output format was consistent, your team could re-run the config without rebuilding it, and you didn't have to re-find the endpoint format documentation every time.

But the template design was still on you. The credential injection logic was still on you. Conditional logic about which rows to include, which proxy type to use per row, which port to assign — all of it was still manual configuration. The tool moved the data; the operator carried the logic. And the moment a column was renamed or a new proxy type was added to your Smartproxy plan, the template broke until someone went back in and fixed it.

This is the previous generation. It got the job done, but it required an operator who knew exactly what they were doing.

The Easy Way: Using SheetXAI in Google Sheets

There is a different approach entirely. SheetXAI is an AI agent that lives inside your Google Sheet. It reads the sheet, understands what you're looking at, and through its built-in Smartproxy integration it can generate endpoints, pull catalog data, and write connection strings back into your columns for you. No template configuration, no automation glue, no manual string assembly. You just ask.

Example 1: Generate rotating-session endpoint strings for a list of country codes

For each country code in column A (rows 2–16), generate a Smartproxy backconnect endpoint using rotating session type and write the full connection string into column B

Each row gets a properly formatted connection string — username, password, host, and port concatenated in Smartproxy's expected format — written directly into column B.

Example 2: Pull the full endpoint catalog into a reference sheet

Fetch all available Smartproxy endpoints and write endpoint location, hostname, proxy type, and port range into columns A through D starting at row 2

SheetXAI calls the Smartproxy catalog, maps each field into the right column, and builds a structured reference table your infrastructure team can plan against.
