[Dx4win] Log import problems

[Loren Hunt]

Hello,
I am new to DX4win and am trying to import a large chunk of my logs that are in an excel spreadsheet format. I followed all the steps for the filter and it took all 13,000 + QSOs but about 830 of them had a blank date field. I cannot see anything different about the date for those fields. 

I also tried first converting the logs to ADIF but have been unsuccessful in my attempts at formula manipulation. A few examples on the web proved frustrating as they expected custom macros.

 Any ideas?

Thanks,
AD6ZJ, Loren
