Thanks for sharing this with the community!
I gave it a try and thought I'd share my experience for others. My first attempt returned "Attributes column not found", but that turned out to be user error rather than an issue with the extension. I hadn't selected Include Custom Attributes when exporting the Interactions report, so the required Participant Attributes Formatted column wasn't present in the CSV.
After exporting the report again with Include Custom Attributes enabled and using data that had already gone through the nightly processing, the extension worked perfectly and made the data much easier to analyse in Excel.
Also, have you considered publishing the source code on GitHub? It would be a great learning resource for those interested in understanding the parsing logic and how the extension was built.
Great contribution and thanks again for sharing! 👏
