I have an Excel file with 100,000–150,000 property addresses. I need someone to pull the Zestimate from Zillow for each address and return it in the same spreadsheet. What you need to do: Take the provided Excel file of addresses Find the Zillow “Zestimate” for each property Add the Zestimate back into the corresponding row Important: I am not looking for a scraper/tool — I need the data delivered Accuracy is critical Proof of work required: A sample file with 50 addresses is attached Process those 50 and send it back completed If accurate, this will move to the full dataset Do not apply unless: You have experience scraping data at scale You complete and return the 50-record sample with your message

Hello there! I’ve handled large scale scraping pipelines like this where the real challenge isn’t just extracting data but keeping it stable across tens of thousands of requests, especially with sites like Zillow that aggressively rate limit. I’d approach your 50 sample first using a Python based system with controlled concurrency, rotating sessions, and retry logic so results stay consistent and don’t silently fail, then scale it into a batch pipeline that reads your Excel, resolves each address reliably, and writes back structured results with validation checks so you don’t get mismatched estimates. I won’t overpromise scraping speed, I focus on accuracy and durability so it still works beyond a few runs, and I can share the sample output quickly to validate before scaling. Kindly contact me for further discussion.

Hello, I have thoroughly analyzed your project requirements for the Zillow Zestimate Scraper Automation project. I understand that you have a large dataset of property addresses that require Zillow "Zestimate" values to be scraped and populated back into an Excel spreadsheet. Let's chat and discuss it further. To handle your project, I will start with developing a custom web scraper using Python and BeautifulSoup to extract Zestimate values for each address provided in the Excel spreadsheet. I will ensure the accuracy and reliability of the data extracted by implementing robust error handling mechanisms. The deliverables for this project include a fully automated Zillow Zestimate scraper that can process thousands of records efficiently and accurately. Before signing-off my bid, I would like to ask a question, i.e., "Have you considered the frequency of updates required for the Zestimate values in the Excel file?" Best Regards, Aneesa.

Hi I have experience building large-scale data extraction pipelines, but with platforms like Zillow the main technical challenge is that the Zestimate is not reliably accessible via simple scraping due to dynamic rendering, anti-bot protection, and request throttling. A direct VBA or basic scraper usually fails because of blocked requests, inconsistent HTML, or missing data from search pages. I would solve this by using a controlled browser-based extraction layer (headless automation), combined with address normalization, retry logic, rate limiting, and structured parsing to ensure accuracy and stability across large datasets. The workflow would read your Excel file, process each address safely, extract the Zestimate from the property page, and write clean results back to the dataset. I work with Python, Selenium/Playwright, data pipelines, Excel/CSV processing, and scalable scraping architectures with logging, error handling, and validation layers. For reliability, I would also include checks for missing or ambiguous addresses and ensure the extracted values match the correct property before saving. The sample of 50 addresses is a good approach, and I can use it to validate accuracy, performance, and edge cases before scaling to the full dataset. My focus would be on consistent results and a pipeline that can handle thousands of records without breaking. Thanks, Hercules

DO YOU HAVE ACCESS TO THE API? Evening! I'm Hassan, a skilled software engineer known for my passion in blending functionality and visual appeal into seamless user experiences. Having read through your project description, I understand that accuracy and scalability are crucial here -- two things that have always been at the core of my work. With my extensive experience in Big Data and Python, I have completed various web scraping projects at scale - and yours would be no exception. My proficiency in Python lends itself perfectly to this task. I am well versed in retrieving specific data from websites, making your large dataset of property addresses well within my repertoire. I've used similar techniques with other insightful real estate platforms, aiding the extraction of valuable information like you need with Zillow's "Zestimate". You'll find that my skills in automation are fantastic for handling datasets such as yours; my goal is to make repetitive manual tasks redundant. One thing I'd like to discuss is whether there's access to the Zillow API. It could help streamline the process and ensure ongoing impeccable data delivery. Nonetheless, even if we don't have access to an API, I can still guarantee a reliable and efficient solution for you.

This is exactly what we specialize in, and we can efficiently build a scalable, automated data extraction pipeline to retrieve Zestimate values from Zillow and map them back into your Excel dataset with high accuracy. We typically use Python-based scraping frameworks, headless browser automation (Playwright/Selenium), and resilient architecture with proxy rotation, rate-limit handling, and retry logic to ensure stable extraction at 100K+ scale. We will begin with a proof-of-concept on your 50-record sample to validate parsing accuracy, address resolution, and data consistency before scaling into a full production-ready workflow that outputs cleanly back into Excel/CSV. Can you share the sample file so we can review the structure and start the POC right away?

Hi, I have strong experience with Python, Excel data processing, large-scale web scraping, and automation workflows, including building reliable extraction pipelines with proxy handling, retry logic, structured parsing, and output validation for high-volume datasets. I have real hands-on experience with large address-based data extraction projects, and for this I would start with the 50-record proof of concept, validate matching accuracy carefully, and then structure the full workflow so each address is processed consistently and the returned Zestimate data is written back into the correct Excel rows with clear error handling for misses or ambiguous matches. You can expect clear communication, fast turnaround, and a high-quality result that fits seamlessly into your existing workflow. Best regards, Juan
