Issue encountered during the process of importing Excel information utilizing the xlsx library

Currently, I am attempting to incorporate excel data into my angular application using the following library:

xlsx

However, upon downloading the project and attempting to run it locally, I encountered an error when trying to upload the excel file:

Uncaught SecurityError: Failed to construct 'Worker': Script at 'file:///E:/Experiments/js-xls-master/xlsworker2.js' cannot be accessed from origin 'null'.
Has anyone encountered similar issues or has experience with this library? Any insights on how to resolve the above problem would be greatly appreciated.

python -m SimpleHTTPServer

Once you do this, your site will be accessible at
