Mastering Scraped Data Management (AI Tips Inside)

Grabbing data from a webpage with HTML parsing is just the first step in a data management pipeline. You then need to prep that raw data for export so your team or company can actually extract value from it! 💡

In this article, we’ll explore the classic techniques alongside the latest and greatest innovations for automatic data processing and export of scraped data. Get ready to level up your data game! 🎓

Next Steps After Extracting Data From a Site

If you've been following this six-part series on advanced web scraping, congratulations! You’ve leveled up your scraping skills to ninja status. 🥷

Here's a quick recap of what you've seen so far:

1. Prerequisites for building a powerful, modern web scraper

2. How to retrieve data from SPAs, PWAs, and even AI-powered sites

3. Tips and tricks to optimize your scraping workflows

4. How to bypass rate limiters with AI-driven proxies

   
   

The bottom line is that your scraping script can tackle even the toughest modern sites, effectively and efficiently extracting all their data. ⚡

Now that you have a treasure trove of data, the next steps are:

• Data Processing: Clean, enrich, and structure your data for export. ⚙️

• Data Export: Store your scraped data for future use in the right format. 📥

  
  

Let’s break down these two final steps and show you how to go from raw scraped data to actionable insights!

Approaches to Processing Scraped Data

Explore the most popular methods for both manual and automatic data processing.

Manual Data Processing

The concept is straightforward: use custom regular expressions and trusty string manipulation methods like trim(), replace(), or other standard library functions to clean the data. And then, if needed, convert it into the right data type. 🧹

Let’s face it—you’ve probably done this before. So, it shouldn’t be anything new… 🧐

Imagine you scraped this string from a product price:

"  USD 199.98 "

You want to extract the price number and currency. Here’s how you might tackle it in JavaScript:

let priceString = "   USD 199.98  "; // scraped string
let trimmedPriceString = priceString.trim(); // removes extra spaces
let [price, currency] = trimmedPriceString.match(/[A-Za-z]+|\d+\.\d+/g).map(item => item.trim());
console.log(price); // 199.98
console.log(currency); // USD

Looks simple, right? But here’s the problem: this kind of manual data cleaning works for most scraped pages; it’s not foolproof. 😭

So, manual data processing often requires logic to handle edge cases. Why? Because web pages evolve and can contain unique data, even if they’re part of a specific page category!

💡 Pro tip: While manual optimization may get the job done, it’s a bit old school. The newest approach is to supercharge your pipeline with AI-based tools for automatic data processing.

Automated Data Processing With AI

AI—especially LLMs (Large Language Models)—is revolutionizing data processing. These models excel at extracting clean, structured information from even the dirtiest, most chaotic, and noisy data. Why not leverage their power for web scraping?

The idea here is to collect all your raw data via web scraping and then pass it to AI to do the data cleaning for you. For example, consider the example below 👇

Here’s the input string:

"  USD 199.98 "

Ask ChatGPT or any other LLM to extract the price and currency for you:

The result? Just brilliant!

Now imagine integrating the above logic directly into your scraper by calling an AI API (e.g., OpenAI, Anthropic, or other LLM providers). That would be avoiding all tedious custom cleaning logic and edge-case debugging! 🙅‍♀️

🎁 Bonus Info: AI isn't just about cleaning your data! It's also a powerful tool for enriching it. LLMs come with built-in knowledge that can add valuable data points or even fetch related info from other online sources.

The only downsides with this approach—particularly if you opt for non-open-source AI models?

• Cost: While calling AI models hasn’t an exorbitant price, it’s not free either—especially at scale. 💸
• Data privacy: Sending your scraped data to a third-party AI provider can raise compliance issues. 🔓

Best Export Methods for Scraped Data

Now that you’ve got data processing down, it’s time to dive into exporting your data with some of the most effective methods. 🤿

⚠️ Warning: While some export methods may sound familiar, don’t be discouraged—others might be more complex and a bit on the exotic side!

Export to Human-Readable Files

Exporting data to human-readable formats like CSV, JSON, or XML is a classic method for storing scraped data. How to achieve that? With a custom data export code at the end of your scraping script!

👍 Pros:

• Easy to read and understand data formats

• Universal compatibility with most tools, including Microsoft Excel

• Can be easily shared with non-technical users and used for manual inspection

  
  

👎 Cons:

• Limited scalability for large datasets
• Old-fashioned approach to data export

Export to Online Databases

Redirecting scraped data directly to online SQL or NoSQL databases, such as MySQL, PostgreSQL, or MongoDB databases.

👍 Pros:

• Centralized access to scraped data

• Supports complex querying

• Easier integration with applications

  
  

👎 Cons:

• Requires database setup and management
• Potential writing performance issues with large volumes of data

Export to Specialized Big Data Formats

Storing scraped data in optimized formats like Protobuf, Parquet, AVRO, and ORC—which are ideal for big data.

Learn more about the differences between JSON and Protobuf in the video below:

👍 Pros:

• Highly efficient in storage and retrieval

• Great for large datasets with complex structures

• Supports schema evolution

  
  

👎 Cons:

• Requires specialized tools for reading, as they are not human-readable
• Not ideal for smaller datasets

Export to Stream-Compatible Data Files

Streamable formats like NDJSON and JSON Lines allow for exporting data in a way that's efficient for real-time applications or processing.

👍 Pros:

• Perfect for streaming and real-time processing
• Supports large volumes of data efficiently
• Flexible and scalable, in both reading and writing, while remaining human-readable

👎 Cons:

• Not all JSON libraries support them
• Not so popular

Export to Cloud Storage Providers

Saving scraped data to cloud storage—just like AWS S3 or Google Cloud Storage—offers easy, scalable, and accessible storage.

👍 Pros:

• Unlimited scalability, especially in cloud-based web scraping
• Easy access from anywhere
• Low maintenance compared to physical storage

👎 Cons:

• Ongoing storage costs
• Requires internet connection to access

Export via Webhooks

Webhooks send data directly to external services in real-time, opening the door to immediate action or processing.

Don’t know what webhooks are? Watch this video:

👍 Pros:

• Immediate data delivery

• Automates data transfer to external systems

• Great for integrations with third-party services—for example, via Zapier or similar platforms

  
  

👎 Cons:

• Requires external service setup
• Potential for data loss if service is down
