Your file is not an XLS. Renaming it XLS has not made it actually be an XLS.

awk does not have infinite precision. If you need infinite precision, use the bc tool. If you can convince awk to print a list of lines like

Code:
a=-9992411.01
a=a+(-4992005.13)
...
a

and feed that into bc, it will print a total.

Code:
awk -F, 'NR==1 { print "a=",$7 ; next }  { print "a=a+("$7")"; } END { print "a" }' inputfile.csv | bc
