Based on the Unix workaround for the SpreaD3 CORS issue, I created an equivalent solution for Windows® users (tested on Windows® 7/10/11).
Add both the RUNConvertSpreaD3.cmd and ConvertSpreaD3.ps1 files to the d3renderer directory within your SpreaD3 output.
Run the script by double left-clicking on RUNConvertSpreaD3.cmd.
You may need to give the necessary permission for the script to run successfully.
The script will generate two new files, index-new.html and main-new.js. Open the index-new.html file with your browser.
The original broken files are removed during the script process.
This script is specific for the latest version of SpreaD3 v0.9.7.1rc.
