How to Build a Powerful Web Scraper in PowerShell (2026 Guide)

Building a web scraper in PowerShell is not as hard as it may sound. As a configuration and automation engine, Windows PowerShell has evolved far beyond simple system administration. In 2026, PowerShell Core, an advanced version with cross-platform properties and object-oriented support, offers robust web scraping capabilities that rival any modern web scraping tool.

This ultimate guide will show you how to scrape data from any web page or HTML web page in a structured, efficient, and reliable way. You’ll learn how to scrape web pages, make an api request or invoke the webrequest cmdlet, and export CSV files, all using simple, lightweight commands.

By the end, you’ll be able to handle repetitive tasks in a truly structured manner. Let's start!

Quick Answer (TL;DR)

Here’s a complete example PowerShell script that demonstrates web scraping with PowerShell using ScrapingBee’s API:

$apiKey = "YOUR-SCRAPINGBEE-API-KEY"
$targetUrl = "https://books.toscrape.com"
$apiUrl = "https://app.scrapingbee.com/api/v1/?api_key=$apiKey&url=$targetUrl&render_js=false&extract=%7B%22products%22%3A%5B%7B%22name%22%3A%22h3%20a%40title%22%2C%22price%22%3A%22.price_color%22%2C%22image%22%3A%22.image_container%20img%40src%22%7D%5D%7D"

$response = Invoke-RestMethod -Uri $apiUrl
$response.products | Export-Csv -Path "scraped_products.csv" -NoTypeInformation

The following script uses ScrapingBee’s powerful wrapper to send an api request to the API endpoint URL and return clean JSON format data directly. It’s a great way to begin extracting data using PowerShell.

Setting Up PowerShell Core for Web Scraping

Before diving into scraping with PowerShell, you’ll need the right environment. PowerShell Core 7+ provides cross-platform properties, better network handling, and object-oriented support. It’s a scripting language designed for both configuration and automation engine purposes, making it useful for web scraping tasks.

Unlike older builds, PowerShell Core includes support for HTTPS protocols, net libraries, and JSON file processing, perfect for parsing HTML structure or handling an HTTP request status code during the scraping process.

Installing PowerShell Core 7 on Windows/macOS/Linux

PowerShell Core 7+ is essential for modern web scraping projects. Download it from Microsoft’s official repository or use package managers like Chocolatey (Windows), Homebrew (macOS), or apt/yum (Linux).

After installation, verify your version:

pwsh --version

You should see PowerShell 7.0 or higher. This version includes improved HTTP handling, better JSON parsing, and enhanced error management that’s crucial for reliable web scraping operations.

Creating a scraper.ps1 project file

Organize your script with a clean folder structure:

mkdir PowerShellScraper
cd PowerShellScraper
New-Item -Name "scraper.ps1" -ItemType File

Set your ScrapingBee API key as an environment variable:

$env:SCRAPINGBEE_API_KEY = "your-api-key-here"

Run your scraper with:

.\scraper.ps1

This keeps credentials secure while making your command line interface portable and efficient.

Installing PSParseHTML module for HTML parsing

PSParseHTML provides advanced HTML parsing capabilities using the AngleSharp engine. Install it with:

Install-Module PSParseHTML -Scope CurrentUser
Import-Module PSParseHTML

The AngleSharp engine used inside PSParseHTML allows regular expressions, DOM traversal, and structured HTML pages parsing all in PowerShell Core.

It’s a great choice for handling HTML web content and extracting required information in a structured manner.

Extracting and Parsing HTML Content

The core of every web scraping process is retrieving a web page and parsing its content. In PowerShell, this can be done using either the Invoke-WebRequest cmdlet or the Invoke-RestMethod for API request handling.

When you scrape websites, you’re making HTTPs requests to a target website, parsing the front page, index page, or even book page for specific category data.

Using Invoke-WebRequest to fetch static pages

When you need to scrape website content with PowerShell, route your requests through ScrapingBee’s API rather than directly to target sites:

$apiKey = $env:SCRAPINGBEE_API_KEY
$targetUrl = "https://example.com"
$apiUrl = "https://app.scrapingbee.com/api/v1/?api_key=$apiKey&url=$targetUrl&render_js=false&block_resources=true"

$response = Invoke-WebRequest -Uri $apiUrl

For more advanced techniques, check out the Java Web Scraping Handbook, which covers similar concepts.

ConvertFrom-HTML with the AngleSharp engine

Now, to powershell parse HTML locally, use PSParseHTML after fetching content:

$html = Invoke-RestMethod -Uri $apiUrl
$dom = ConvertFrom-Html $html

# Extract specific elements
$titles = $dom.QuerySelectorAll('h2.title')

However, consider using ScrapingBee’s extraction rules first, as they return structured JSON and eliminate parsing complexity.

Local parsing is best reserved for scenarios requiring custom data transformation or when working with already-fetched HTML content.

QuerySelector() vs QuerySelectorAll() usage

Use QuerySelector() for single elements and QuerySelectorAll() for multiple matches:

# Single element
$firstTitle = $dom.QuerySelector('h1')

# Multiple elements
$allLinks = $dom.QuerySelectorAll('a[href]')

These methods provide CSS selector support similar to JavaScript, making it easier for web developers to transition to PowerShell scraping.

Scraping product name, price, and image URL

Here’s how to extract product data using both approaches:

With extraction rules (recommended):

$extractionRules = @{
    products = @(
        @{
            name = "h3 a@title"
            price = ".price_color"
            image = ".image_container img@src"
        }
    )
} | ConvertTo-Json -Compress

$apiUrl = "https://app.scrapingbee.com/api/v1/?api_key=$apiKey&url=$targetUrl&extract=$extractionRules"

With DOM parsing:

$products = $dom.QuerySelectorAll('.product_pod') | ForEach-Object {
    @{
        Name = $_.QuerySelector('h3 a').GetAttribute('title')
        Price = $_.QuerySelector('.price_color').TextContent
        Image = $_.QuerySelector('img').GetAttribute('src')
    }
}

Advanced PowerShell Web Scraping Techniques

Advanced PowerShell web scraping techniques become essential when dealing with complex websites that use pagination, require proxy rotation, or implement sophisticated anti-bot measures. Our platform provides integrated solutions for these challenges, allowing your PowerShell scripts to handle enterprise-level scraping requirements without managing infrastructure complexity.

Modern websites often implement multiple layers of protection against automated access. These include rate limiting, IP blocking, CAPTCHA challenges, and JavaScript-based detection systems. ScrapingBee’s platform addresses these challenges through its proxy network, browser fingerprinting protection, and JavaScript rendering capabilities.

Scraping paginated content with URL patterns

Handle pagination with a simple loop structure:

$results = @()
for ($page = 1; $page -le 10; $page++) {
    $pageUrl = "https://example.com/products?page=$page"
    $apiUrl = "https://app.scrapingbee.com/api/v1/?api_key=$apiKey&url=$pageUrl"
    
    $response = Invoke-RestMethod -Uri $apiUrl
    $results += $response.products
    
    Start-Sleep -Seconds 2  # Rate limiting
}

$results | Export-Csv -Path "all_products.csv" -NoTypeInformation

Our API's concurrency parameter at the plan level allows faster processing. Remember, you only pay for successful responses, making pagination cost-effective.

Using proxies with Invoke-WebRequest -Proxy

With our platform, you also get a “Proxy Mode”, so you don’t need to manage raw proxy lists.

If your PowerShell script requires the -Proxy parameter, point it to the API's proxy endpoint:

$proxyUrl = "http://premium-residential:$apiKey@premium-residential.scrapingbee.com:8886"
$response = Invoke-WebRequest -Uri $targetUrl -Proxy $proxyUrl

This approach provides access to the premium residential proxy network with automatic rotation and geographic targeting. The proxy mode handles authentication and rotation automatically, simplifying your PowerShell code significantly.

Avoiding anti-bot blocks with ScrapingBee

The integrated anti-bot protection works automatically:

$apiUrl = "https://app.scrapingbee.com/api/v1/?api_key=$apiKey&url=$targetUrl&stealth_proxy=true"

The platform handles browser fingerprinting, request patterns, and other detection methods transparently. This eliminates the need for complex anti-detection logic in your PowerShell scripts.

Scraping JavaScript-rendered pages using the Selenium module

When dealing with pages heavily dependent on JavaScript rendering, you can use the Selenium PowerShell module for local browser automation. While Selenium provides full control, enabling clicks, scrolls, and waits, it consumes significant local resources and may trigger anti-bot systems more easily. In contrast, ScrapingBee’s API simplifies the process with the render_js=true parameter or the JS Scenario feature, which lets you simulate interactions like scrolling or button clicks directly on the server side.

Using the API first is generally recommended. It’s more stable, scales easily, and ensures transparent credit usage since you’re charged only for successful renderings. Reserve Selenium for debugging or testing scenarios where full browser control is essential.

Exporting and Structuring Scraped Data

Proper data structuring and export are crucial for making your scraped data useful. PowerShell’s object-oriented nature makes it easy to create structured data that can be exported to various formats. Using ScrapingBee’s extraction rules reduces the complexity of local data processing by providing clean JSON output directly.

The key to effective data export is consistency in your data structure. Whether you’re scraping product information, news articles, or contact details, maintaining consistent field names and data types ensures your exported data is immediately usable for analysis or integration with other systems.

Creating custom PowerShell objects for scraped items

Transform parsed data into structured objects:

$products = foreach ($item in $scrapedData) {
    [PSCustomObject]@{
        Name = $item.name.Trim()
        Price = [decimal]($item.price -replace '[^\d.]', '')
        ImageUrl = if ($item.image.StartsWith('http')) { $item.image } else { "https://example.com$($item.image)" }
        ScrapedDate = Get-Date
    }
}

This approach normalizes data types and ensures consistent formatting across all records.

Exporting data to CSV using Export-Csv

PowerShell’s Export-Csv cmdlet provides flexible export options:

# Overwrite existing file
$products | Export-Csv -Path "products.csv" -NoTypeInformation -Encoding UTF8

# Append to existing file
$products | Export-Csv -Path "products.csv" -NoTypeInformation -Append

I suggest always using -NoTypeInformation to avoid PowerShell type headers in your CSV files. UTF-8 encoding ensures proper handling of international characters.

Handling errors and failed requests gracefully

Implement robust error handling with retry logic:

function Invoke-ScrapingBeeRequest {
    param($Url, $MaxRetries = 3)
    
    for ($i = 0; $i -lt $MaxRetries; $i++) {
        try {
            $response = Invoke-RestMethod -Uri $Url
            return $response
        }
        catch {
            Write-Warning "Request failed (attempt $($i+1)): $($_.Exception.Message)"
            if ($i -eq $MaxRetries - 1) { throw }
            Start-Sleep -Seconds (2 * $i + 1)
        }
    }
}
