Hi there,
Your project description is unclear. From what I understand, you want to scrape the data from a chrome extension. I can develop the extension with Javascript (all browser extensions are developed by Javascript). To get started, share the following:
1. The site of interest what needs to be scraped by the extension
2. The format of the scraped data
3. The data points that need to be scraped
Let me know what you think of my offer. Thanks for your time and consideration.
