Wen you copy table data out of wikipedia and paste it into Excel you get messing looking things like

&0000000000230000.000000230,000[2]
&0000000000013575.00000013,575[4]
&-1-1-1-1-1-1-1-1-1-1-1-1-1-1-1-1.000000

To convert those to usable numbers (or blanks, where appropriate) here’s an Excel formula you can use:

=IF(ISERR(FIND(“-”,C2)),IF(C2=”",”",VALUE(MID(C2,2,FIND(“.”,C2)-2))),”")
