First, we need to scrape updated data about Korea from the CDC. Feel free to practice by yourself with the crawler file.
Data extraction consists of 3 steps:
- Step 1: Build a scraper task by entering the URL
- Step 2: Click to extract the web data
- Step 3: Execute the scraper task
Sounds easy right? Well, it is very easy!
First, paste the web URL to the box after clicking the “Advanced Mode”. Then click “Save URL” to proceed. It will load the web page in its built-in browser for you to click and extract.
Next, click on any table cell and follow the guide that appears on the“Action tips” Panel. Choose “Select all sub-elements”, then click “Select all”. Congratulations! We just create a scraper successfully. Now we should confirm the step by clicking “Extract data in the loop”.
Last but not least, click to execute the scraper.
As we complete fetching the data, we can export to an excel format and use it to create a map visualization. I understand how data can be easily outdated over time, especially for time-sensitive data. At this point, you can take advantage of its scheduler to put your task on autopilot.
