Digital Financial Reporting

I mentioned some Excel-based extraction and validation tools that I created.

Well, I created an improved version.  There are two significant improvements to this fundamental accounting concepts validation tool:

1. Validate one file at a time.  Rather than validating many different files and then comparing them like the other tools, this one validates ONE filing at a time to let you focus on that filing.  Again, you can use a URL from the SEC EDGAR repository or a local file.
2. I added what I call a "line of reasoning" output to help you understand what the tool is doing.

Let me know what you think.  I believe the line of reasoning turned out nice.  I know that there is a lot of room for improvement such as formatting the numbers, providing additional information, etc.  You can add that functionality yourself.
