Zillow to Google Sheets, comps logged cleanly
Copying Zillow data into a spreadsheet feels simple. Then you do it for 20 listings, your rows don’t line up, and you’re double-checking prices because one bad paste ruins the comp set.
This is the kind of mess that slows down real estate investors first, but agents and market researchers feel it too. With this Zillow Sheets automation, you can turn a list of Zillow URLs into a clean “Results” tab that’s ready for analysis, not cleanup.
Below you’ll see exactly what the workflow does, what you get out of it, and how to avoid the common setup traps that make scrapes fail.

The Problem: Comps Data Gets Messy Fast
If you’ve ever tried to build comps from Zillow manually, you already know the pain isn’t the “work.” It’s the constant micro-decisions and corrections. One listing has a slightly different layout. Another loads slowly. You paste an address into the wrong column and don’t notice until you’re halfway through your analysis. Even worse, Zillow’s pages can be inconsistent, so you end up with blank cells, weird text chunks, or “undefined” where a key value should be. Multiply that by dozens of URLs and you’re burning an afternoon on what should be simple research.
It compounds in a few predictable places.
- You waste about 5–10 minutes per listing just collecting the basics (price, address, days on Zillow, zestimate).
- Manual entry creates silent errors, and those errors make your comp conclusions less trustworthy.
- When you need to refresh the same listings next week, you do the same work again because there’s no repeatable process.
- Zillow’s anti-bot protections break many “quick scraping” hacks, so you lose time troubleshooting instead of analyzing.
The Solution: Zillow URLs In, Clean Google Sheets Rows Out
This n8n workflow automates the whole comp-logging loop. You start with a simple input sheet that contains Zillow URLs. When you run the workflow, it reads each URL, sends it to Scrape.do (a scraping API designed to get past Zillow’s PerimeterX and other protection), and pulls back the full page HTML. From there, the workflow parses the HTML into structured property fields like price, address, city, state, days on Zillow, and zestimate. Finally, it appends one clean, consistent row per property into a “Results” tab in Google Sheets, with a scrape timestamp so you can track when the data was collected.
The workflow starts with a manual run from n8n, then reads your URL list from Google Sheets. Scrape.do fetches each page, the workflow validates the response, and the parsing step extracts only the fields you care about. At the end, your comps are logged in a standardized table you can sort, filter, and analyze immediately.

Example: What This Looks Like
Say you’re pulling comps for one neighborhood and you collect 20 Zillow URLs. Manually, if it takes about 7 minutes per listing to copy price, address, days on Zillow, and zestimate into the right columns, that’s roughly 2+ hours (and you still have to sanity-check the sheet). With this workflow, you paste the 20 links into “Sheet1,” run it, and wait maybe 3–4 minutes for scraping and parsing. You get a filled “Results” tab with uniform rows and a “Scraped At” timestamp for each property.
What You’ll Need
- n8n instance (try n8n Cloud free)
- Self-hosting option if you prefer (Hostinger works well)
- Google Sheets to store input URLs and results.
- Scrape.do to reliably fetch Zillow HTML.
- Scrape.do API token (get it from your Scrape.do dashboard).
Skill level: Intermediate. You’ll connect Google Sheets credentials, paste an API token, and confirm your sheet tabs/columns match the expected format.

How It Works
A manual run kicks things off. You execute the workflow when you’re ready to pull a fresh batch of comps (or swap in a schedule later).
Your Google Sheet provides the URL list. n8n reads the “Sheet1” tab and looks for a column header named “URLs,” then processes each link in that column.
Scrape.do fetches the listing page reliably. The workflow sends each Zillow URL through the Scrape.do API (using the super=true option for premium residential proxies), then checks the response so it doesn’t parse garbage.
Parsed fields get appended as clean rows. The workflow extracts the listing details you care about and writes them into a “Results” tab in Google Sheets, including a scrape timestamp so you can track freshness.
You can easily modify the extracted fields to capture things like beds, baths, or square footage based on your needs. See the full implementation guide below for customization options.
Step-by-Step Implementation Guide
Step 1: Configure the Manual Trigger
This workflow starts manually and uses a note node for on-canvas documentation.
- Add or confirm the Manual Launch Trigger node as the starting trigger.
- (Optional) Keep Flowpast Branding as a reference note on the canvas; it does not affect execution.
- Connect Manual Launch Trigger to Retrieve Zillow Links Sheet.
Step 2: Connect Google Sheets
Pull source URLs from Google Sheets and prepare the destination sheet for output.
- Open Retrieve Zillow Links Sheet and select the Spreadsheet ID
1D2cU-NoW4ubx_IQ6piRRO3_d0Fx7jzdpWxKkBqEq7HU. - Set the Sheet Name to
URLs(gid0). - Credential Required: Connect your googleSheetsOAuth2Api credentials in Retrieve Zillow Links Sheet.
- Open Append Results to Sheets and set the Operation to
append. - Set the destination Sheet Name to
Outcome(gid2048497939) and the same Spreadsheet ID1D2cU-NoW4ubx_IQ6piRRO3_d0Fx7jzdpWxKkBqEq7HU. - Credential Required: Connect your googleSheetsOAuth2Api credentials in Append Results to Sheets.
URLs, since Scrape Zillow via API uses $json.URLs to build the request.Step 3: Set Up the Scraping and Validation Logic
These nodes send the Zillow URLs to Scrape.do, validate the response, and prepare data for extraction.
- In Scrape Zillow via API, set the URL to
{{ "https://api.scrape.do/?url=" + encodeURIComponent($json.URLs) + "&super=true" }}. - Set Authentication to
genericCredentialTypeand Generic Auth Type tohttpQueryAuth. - Credential Required: Connect your httpQueryAuth credentials in Scrape Zillow via API.
- In Validate Scrape Result, configure the condition: Value 1 =
{{ $json.statusCode }}, Operation =equals, Value 2 =200. - Connect Retrieve Zillow Links Sheet → Scrape Zillow via API → Validate Scrape Result → Extract Zillow Details.
Step 4: Configure Data Extraction and Output
Parse the HTML response and append structured results to your output sheet.
- Open Extract Zillow Details and confirm the JavaScript Code extracts fields like
Price,Address,City,State,Days on Zillow,Zestimate, andScraped At. - Note the reference to the original URL:
$('Retrieve Zillow Links Sheet').first().json.URLs. This ties each scrape to its input URL. - Connect Extract Zillow Details to Append Results to Sheets.
- In Append Results to Sheets, keep Mapping Mode set to
autoMapInputDataso JSON fields map to columns automatically.
N/A. Update the patterns in Extract Zillow Details when needed.Step 5: Test and Activate Your Workflow
Run a manual test to confirm the pipeline works end-to-end, then enable it for production use.
- Click Execute Workflow to trigger Manual Launch Trigger.
- Verify Scrape Zillow via API returns a
200status code and passes through Validate Scrape Result. - Check Append Results to Sheets and confirm a new row is added in the
Outcomesheet with fields likePriceandAddress. - Once validated, save and activate the workflow for regular use (or keep manual for on-demand runs).
Common Gotchas
- Google Sheets credentials can expire or need specific permissions. If things break, check the Google Sheets OAuth connection inside n8n’s Credentials panel first.
- If you’re scraping large batches, processing times vary. Add or increase a Wait node between requests if downstream parsing fails because the response is empty or incomplete.
- Scrape results can look “successful” but still change over time because Zillow updates HTML structure. If price or address suddenly comes back as weird HTML/CSS, update the parsing logic in the “Extract Zillow Details” step instead of forcing it in Sheets.
Frequently Asked Questions
About 30 minutes if your Google Sheet is ready.
No. You’ll mostly be connecting accounts and pasting in your Scrape.do token.
Yes. n8n has a free self-hosted option and a free trial on n8n Cloud. Cloud plans start at $20/month for higher volume. You’ll also need to factor in Scrape.do usage, since this workflow uses 1 request per URL and premium mode can cost about 10 credits per request.
Two options: n8n Cloud (managed, easiest setup) or self-hosting on a VPS. For self-hosting, Hostinger VPS is affordable and handles n8n well. Self-hosting gives you unlimited executions but requires basic server management.
Yes, and honestly it’s one of the best reasons to use n8n for this. You’ll extend the parsing logic in the “Extract Zillow Details” step to capture additional fields (beds, baths, square footage, lot size). Many teams also add filtering after “Validate Scrape Result” to skip listings outside a target price range. If you want this to run daily, replace the manual trigger with a schedule trigger and keep the same Google Sheets input/output structure.
Usually it’s an expired OAuth connection in n8n, so re-authenticate your Google Sheets credentials and reselect the correct account. Also confirm your spreadsheet ID is correct and that your input tab has a header exactly named “URLs.” If the sheet was moved to a shared drive or a different Google account, permissions can change quietly and cause “permission denied” errors.
Plenty for normal comp work: 10 URLs usually finish in about 1–2 minutes, and 50+ often completes in around 5–10 minutes depending on Scrape.do credits and response times.
For Zillow scraping, usually yes, because Zapier and Make aren’t built for “fetch HTML, validate it, parse it, then write structured fields.” n8n handles branching logic, code-based parsing, and error handling in one place without turning every extra step into another paid task. If you’re only moving already-clean data from one app to another, Zapier or Make can be simpler. But once scraping is involved, you want more control. Talk to an automation expert if you’d like help choosing.
Clean comps are hard enough to interpret. Your spreadsheet shouldn’t be the part that fights you. Set this up once, and the workflow does the repetitive collection work whenever you need fresh data.
