What I'm having trouble with is getting all that into a Gedcom. Nothing I've tried, works. I have to manipulate the columns and data so much I risk losing data.
Let me try and understand you. You are trying to convert an Excel spreadsheet into a gedcom file? I would have thought that was impossible.
Basically, a gedcom file uses a database consisting of 3 major tables:
Individuals (I numbers)
Groups (F numbers)
Notes (N numbers)
Individuals contains:
Individual ref number (e.g. I0100)
First, middle and surname
where and when born
gender
where and when died details
ancestry ref number (e.g. F020)
descendancy ref number (e.g. F001)
Groups contains:
Husband ref number (e.g. I0100)
Wife ref number (e.g. I0101)
Where and when married
Children ref numbers (e.g. I0300, I0301, I0302, I0303)
Notes contains:
Notes based on the Individual ref number e.g. I0100 is N0100 in the notes table.
All the tables are contained in the one file but they are laid out in a specific area of the file i.e. Individuals, followed by Groups, followed by Notes. There is also a 4th table called Sources (S numbers), which is relatively small.
Organising your data by having separate workbooks for births, marriages and deaths is also fraught with difficulty.
