How to Connect BuiltWith to Excel (4 Methods Compared)

The Problem With Getting Excel Data In and Out of BuiltWith

You have an Excel workbook full of domains — prospect lists, competitor trackers, acquisition targets, outreach pipelines. You need it enriched with technology data from BuiltWith, or you need BuiltWith's bulk domain lists pulled directly into a worksheet so you can filter and work with them.

BuiltWith is good at answering the question "what is this website built on?" at scale. But extracting that answer for hundreds of domains, or pulling the list of all sites running a given tool, is not a click-and-export operation. The default flow is API calls, JSON parsing, column mapping by hand — or exporting a CSV from BuiltWith, reformatting it, and pasting it into the existing workbook every time the list updates.

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

Method 1: Manual Copy-Paste

The default for Excel workflows tends to be the CSV export: pull a BuiltWith report, open it in Excel, delete the columns you don't need, and use XLOOKUP to merge it with your existing worksheet. Or go row by row on BuiltWith's site for smaller lists.

For a handful of domains this is a short task. For a list that grows every week, the CSV merge becomes its own recurring workflow — download, reformat, remove duplicates that appeared twice across exports, check that the columns still match. The inconsistency in BuiltWith's per-domain output means the schema never looks exactly the same twice, and somebody has to reconcile that before the workbook is usable. That somebody is usually you.

Method 2: Power Automate

Power Automate has BuiltWith connector options. You can configure a flow to trigger on a new row in Excel, call the BuiltWith API, and write the enrichment back to adjacent columns.

A quick check before you keep reading — are you comfortable with Power Automate's REST API action, dynamic content mapping, and expression syntax? If those aren't part of your regular toolkit, the path ahead is steeper than it looks. Method 3 or 4 will get you there faster.

If you're still reading, the flow itself is achievable: authenticate to BuiltWith, set up the Excel trigger, map the response fields to the right columns. It runs.

The problem is per-row architecture.

Each new domain triggers one API call. A worksheet with 400 domains means 400 flow runs. When BuiltWith returns a field in an unexpected format on row 87 — an array where the flow expected a string — the expression fails silently. Nothing gets written. You won't know until someone notices the gaps.

You probably just need the enrichment columns populated for the outreach list sitting in your workbook. You probably have no idea why the flow stopped writing after row 200, and you probably don't have the time to step through the run history for each failed record. So this goes to whoever on your team manages Power Automate flows, and you wait for a response in Teams.

And once you need aggregate logic — filter to only domains running a specific CMS, or score rows by which technologies co-occur — the per-row flow can't do it. That logic has to live somewhere else, which means more glue, more places for things to break.

Method 3: The Previous Generation — Connector Add-Ons

Until recently, the best option for repeatable BuiltWith enrichment inside an Excel workbook was a category of add-ons that let you configure API calls, map response fields to worksheet columns, and save those configs for reuse. You set it up once, the team could re-run it, and the output stayed consistent across runs.

That was a real improvement over exporting and merging CSVs manually. The column mapping held, the schema was predictable, and you didn't have to reformat the export every week.

But the template was still yours to own. A renamed column in your workbook broke the config. A new technology category in BuiltWith's response that didn't match an existing field target got dropped silently. The add-on got the data through. It didn't adapt to what changed.

This is the previous generation. It worked, but it asked the operator to maintain the mapping indefinitely.

The Easy Way: Using SheetXAI in Excel

There is a different way entirely. SheetXAI is an AI agent that lives inside your Excel workbook. It reads the workbook, understands what you're looking at, and through its built-in BuiltWith integration it can enrich your domain list, pull technology user lists, or audit redirects for you. No template configuration, no API mapping, no post-processing. You just describe what you need.

Example 1: Bulk-enrich a prospect list with tech stacks

Look at the domains in column A. For each one, use BuiltWith to find their CMS, analytics platform, e-commerce platform, and CDN. Write the results to columns B, C, D, and E. Flag any domain using Shopify or WooCommerce in a new column called E-Comm Flag.

SheetXAI runs the enrichment across all rows, maps each BuiltWith field to the right column, and adds the conditional flag — all in one pass.

Example 2: Pull a technology user list into a blank worksheet

Use BuiltWith to get the first 500 websites currently running Marketo. Write each domain, country, and detected technology categories to this worksheet starting at row 2.

The pattern: instead of configuring a Power Automate flow and debugging the field map, you describe the output you want and SheetXAI handles the retrieval and formatting inline.

Try It

Get the 7-day free trial of SheetXAI and open any Excel workbook with a list of domains or a blank worksheet ready for a technology user list, then ask it to do one of the tasks above. The BuiltWith integration is included in every SheetXAI plan.
