Copying Safari History

Question

I know that I can find the Safari history file on my Macbook Pro ( late-2012) running Mavericks 10.9.1 here:
~/Library/Safari/History.plist
I know, too, that I can use python libraries and so forth to read the .plist file.
What I don't understand is that, when I look at the history page of Safari, I already have exactly what I want - a table with 'Website', 'Parent', 'Address' in three columns, with the date of my visit in the 'Parent' column. All I want to do is copy and paste this into a spreadsheet, Numbers, say. It's simple, really, it's a handy way for me to work out where I've been spending my time so I can put together an accurate timesheet.
However, I can't use it. I select it and copy it - that works fine, but, when I past it, I only get the first column, 'Website'.
What is iTunes doing? I've not seen this behaviour elsewhere, where you simply can't copy some columns.
Is there a way to get around it? If I try to e-mail it, I simply get an e-mail with no content.
It would be an awful lot easier to just use this, rather than mess about with the .plist files.

Answer 1

Then there's no way to recover the lost data. You will lose every bit of data you have if you don't start backing up.
