How to Choose the Right Data Extractor?
Selecting the right tool for your needs requires evaluating several criteria. Here are the data extraction methods to prioritize based on your context.
✅ Essential Selection Criteria
Ease of Use: no-code interface if you're not a developer
Example: Amazon results page (lots of prices in one place), type Amazon.fr → search “SSD 1TB”.
Here are some prerequisites before starting:
An Amazon results page (not a single product page).
The list of fields to extract: Name, Price, URL (optional: rating ⭐, number of reviews).
1: Registration
Go to the Octoparse website and click Sign Up
Create an account (email + password or Google, depending on the option shown)
Verify the email if requested
Download and install Octoparse Desktop
Open the app → Log In
2: Create a Task and Open the Amazon Page
In Octoparse, click New Task
Select Advanced Mode (more reliable)
Paste the Amazon page URL (search results)
Click Start
If a cookie banner appears, click Accept (directly in the integrated browser)
Pro tip: wait 2–3 seconds for the page to fully load before selecting anything.
3: Auto-Detection
Click Auto-detect Web Page Data
Octoparse suggests a “list” extraction → click Create workflow
Open Data Preview to check if you can already see:
product titles
a price (at least on some lines)
If the preview mixes elements (ads, sponsored blocks), don't worry: we'll clean it up in the next step.
4: Correctly Extract Name, Price, URL
On Amazon, the price is often displayed in two parts (euros + cents). The goal: to get a usable price.
Here's how to do it:
On the page, click on a product title
Select Select all similar (select all similar titles)
Then Extract text → column product_name
For the product URL:
Re-click the title → Extract link URL → column product_url
For the price:
Click on the “€” part of the price (or the price area)
Select all similar → Extract text → column price_raw
If price_raw comes out wrong (e.g., “19” without “,99”):
Select euros → extract price_euros
Select cents → extract price_cents
Then, after export, recombine in Excel (=A2&","&B2) or in your pipeline (simpler, more stable).
Here's a checklist of fields
🛒 Amazon → Octoparse: What to Click and What to Extract
Field 🎯
Where to Click on Amazon 🖱️
Octoparse Action ⚙️
Name 🏷️
Product title
Select all similar → Extract text
URL 🔗
Product title/link
Extract link URL
Price 💶
Price area
Select all similar → Extract text
Rating ⭐ (optional)
Stars
Extract text
Reviews 🧾 (optional)
“xxx reviews”
Extract text
5: Pagination
On the Amazon page, locate the Next button (at the bottom)
Click Next once
In Octoparse, choose Loop click next page / Pagination
Check in the workflow that the order looks like:
Loop (Next page) → Extract data
Tip: run a test on 2 pages to confirm that the lines are indeed increasing.
6: Make the Extraction Stable
In the workflow options (or each step):
Add a Wait (1 to 3 seconds) before extraction
Enable Scroll page if results load on scroll
Enable Retry if some lines come out empty
Avoid too-fast extractions: it increases errors
7: Start the Extraction
Click Run
Choose Local Run for an initial test
Run a short test (1–2 pages) then check the data
8: Export (CSV / Excel)
Open the Data tab
Click Export
Choose CSV (the most universal) or Excel
Tip: always keep product_url in the export. It's your “ID” for deduplication and tracking changes.
⭐️ Bonus: Only Retrieve New Items
The simplest way:
Rerun the task regularly
Deduplicate on product_url in your file/tool (Sheets/Excel/BI)
Add a date_extraction column for history
Amazon often changes its display, and some pages impose access limits. If you have an official alternative (e.g., partner API), it's often more stable for long-term use.

FAQ
What is a data extractor?
A data extractor is a data extraction software that collects information from a source (website, file, database, API) and converts it into usable data (CSV, table, JSON) to automate collection, reduce errors, and speed up analysis.
What is the purpose of a data extractor in business?
It is used to industrialize the reading and consolidation of a set of dispersed data: competitive intelligence, price monitoring, reporting, CRM enrichment, quality control, compliance, or feeding an ETL pipeline.
What types of data can be extracted in concrete terms?
Common examples: product names, keywords, prices, availability, availability, public company contact information, reviews, technical attributes, PDF tables, form fields, history, and metadata.
What are the most common use cases in 2026?
Market analysis and monitoring (prices, catalogs, trends)
Web scraping for e-commerce (product monitoring)
CRM enrichment and cleaning (standardization, deduplication)
Extraction of documents (invoices, purchase orders, contracts)
Process automation (recurring workflows + export)
OCR extraction for better document management
Web scraping: why does it sometimes break from one day to the next?
Because sites change their structure, load content via scripts, or add protections. A reliable extractor must manage dynamic loading (scroll, delays), and you must provide quality control (empty field rate, errors, duplicates).
How do you know if a no-code tool is enough, or if a more “technical” solution is needed?
No-code is enough if you have a moderate volume, stable pages, and a “list + export” need. A more technical solution becomes preferable if you aim for: large volume, frequent extraction, high variability of pages, or direct integration into a pipeline (ETL/warehouse).
What key features should you check before buying a tool?
Key features that make the difference:
Pagination and scroll management (dynamic content)
Error detection and management (retry, logs, alerts)
Deduplication, standardization, cleaning rules
Session/cookie management if necessary
How to avoid polluting a CRM with extracted data?
Define a unique key (e.g. URL), standardize the formats (phone, country, currency), do a “staging” (buffer table), then apply rules: deduplication, validation, and historization. Without it, you will “load” the CRM with duplicates and inconsistent data.
Can data be extracted from Google Maps?
Yes, for prospecting or local analysis, some tools can extract business information visible on Google Maps. Do it carefully: focus on strictly necessary data, avoid personal data, and maintain a compliance logic.
Where to store the extracted data: on disks or in the cloud?
On your disks (CSV/Excel) if it is punctual and light. In the cloud if it is recurrent, collaborative, or large. The important thing: governance (who accesses), traceability (date of extraction), and quality control.
What are the signs that your extraction is not reliable?
Too many empty or inconsistent fields
“Impossible” price/value variations from one run to another
Massive duplicates in the same export
“Pub/sponsored” lines mixed with the real dataset
Error rate that increases as you increase volume
What are the 3 classic pitfalls to avoid when starting out?
Extract too many fields “just in case” (cost, noise, maintenance).
Launch on a large scale without testing on a few pages.
Forget the “cleaning + validation” phase before integrating into the final tool.
