In CSV, how to write the header after writing the body?

[Tim]

Here's how I'm approaching this (almost done), I may not finish until morning as it's
1 A.M. here now, but I'm so close, I'm going to try and finish tonight.

My thoughts were to parse the .bib file, creating a dictionary that can be accessed by the ieee id.
then you can simply access all fields by key, value, for example ieee[id]['author']
or ieee[id]['abstract']
To process an entire file, you can use something like:

for key, value in ieee.items():
    ...

The final thing I have to do is handle the exception on line end.
back soon, if not, in the A.M.

Thank you so much Larz60+ for your care and efforts, all are highly appreciated.
Please keep in mind that not all entries are generated by IEEE, some are generated from other journals that are not listed in IEEExplorer. So the .bib file is not necessary to follow IEEE standard.
