Hey ILoveTTATT2
ok, hope you don't mind me jumping in - I had a test run - so konceptual99 this is what I did....
FIRST - Get the best original scan image that you can (that is also straight on the page)
I used one that was 4623 x 3600 pixels (so that's a 16Mb image saved as a 2.9Mb jpeg) - http://imgur.com/a/hMSLM
I edited to remove the horizontal lines (they confuse the OCR)
SECOND - Convert to Excel format
I used my favourite free online OCR website (your's might be different)
Get it converted to Excel, and download in Excel
TIP: you'll find that the OCR converts a few the of commas in the numbers to full-stops - so do a global search-and-replace
Place each part of the converted chart all on to one excel sheet, with columns lined-up
THIRD: Use the Excel column autosum feature to add up each column and compare with the given totals
I think 8 out of 13 columns in my example added up as the given totals - so I assume the individual numbers are all good in those columns
About 4 columns didn't add up correctly - but they had obvious errors when a cell had no number in it or something - easy to spot and correct - once done they added up as the given total
One colum did NOT total up but was out by exactly '1,000' - a bit weird - I took a few minutes to double check the individual numbers and all seemed OK, so actually I think it is a WT mistake....
End result is something like this: http://imgur.com/a/9C6mH
Think it took about 30 minutes-all-in (I was interrupted by a phone call) but that is just converting hard-copy to electronic format which is kinda the easy bit because...
What does take the time is the country-matching from year-to-year....
