Extracting Red Rows from HTML Tables with Selenium VBA

If you have ever worked with web data using Selenium VBA, you might have encountered a situation where you needed to filter specific rows from a table based on their style. In this post, we will explore how to extract rows with red font color from an HTML table and export that data to Excel. This method is particularly useful for efficiently gathering important information from web pages.

The Challenge: Filtering Specific Data

When automating web interactions, it's common to face challenges like:

Extracting specific rows from an HTML table based on their styling or values.

Navigating through the page and interacting with elements dynamically.

Exporting extracted data into a structured format such as an Excel spreadsheet.

In this case, our objective is to identify rows in the HTML table with the ID grdHizmetKontrol that have red font coloring and transfer this data next to the Turkish Identity Number (TC) from a list you input.

The Solution: Using Selenium VBA

To address the challenge of extracting red rows, we can use the following approach with Selenium VBA:

1. Setup Selenium WebDriver

First, ensure that you have set up the Selenium WebDriver in your VBA environment. You can do this by referencing the Selenium library in your VBA project.

2. Connect to the Web Page

We start by initializing Selenium and connecting to the target web page.

4. Extract Required Data

Now, we need to loop through each TC number and extract the rows with red font color. Here’s how to do it:

Explanation of Data Extraction

Looping Through TC Numbers: Each TC number input will trigger a search on the webpage.

Finding Table Rows: We identify the relevant table with grdHizmetKontrol and search through its rows.

Filtering Red Rows: By checking if the row's style contains color:Red;, we can pinpoint the needed rows and extract their data.

Final Step: Closing Connection

Finally, we need to ensure that we close the browser and clean up:

Conclusion

The above VBA script provides a clear and practical way to filter and extract rows from an HTML table based on styling. By following these steps, you can effectively gather the required data and organize it into your Excel spreadsheet, simplifying your data management tasks.

Utilize this method to streamline your data extraction processes and unlock the potential of web automation with Selenium and VBA!
