Select Elements to Scrape:
Use the point-and-click interface to select elements on the webpage you want to extract.

Click on the elements (e.g., text, images, links) you need, and Parse Hub will highlight and recognize similar elements on the page.

Create Selectors:

Run the Project:
Click on the green “Run” button to start scraping.
Choose to run it on the cloud for larger projects or locally for smaller tasks.

Monitor Progress:
Monitor the progress and ensure that the data is being extracted correctly.
If necessary, pause the project to make adjustments to selectors and commands.

Step 6: Exporting Data
Export Your Data: Once the scraping is complete, export your data in the desired format (e.g., CSV, JSON, Excel).

Click on “Get Data” and choose your preferred format for export.

Tips and Tricks

Advanced Selectors:
Use CSS selectors and XPath for more complex data extraction tasks.
Utilize regular expressions for refining your data extraction.
Automating Projects:

Schedule your projects to run at regular intervals to keep your data up-to-date.
Use Parse Hub’s API to integrate scraping results directly into your applications.
Handling Dynamic Content:

For websites that use JavaScript to load content, ensure that you account for dynamic elements by using appropriate delay commands.
