I have this issue only with Excel 2000. I am constructing a .csv file and
flushing it to the client browser where it opens in IE, embedded Excel. My
list separator is set to comma. Still the whole data appears in the frst
column. Like I have 3 strings concatenated by comma like 123,USA,49307.
Excel2000 treats everything as one string and put them in one cell. This
doesn't happen with excel 2003. I cannot want to use "text to columns" bcos
there is another application attached which takes oveer from that point. Why
is this happening? Is there any way I can changes this behaviour to normal
programatically.

Also I donot create any Excel.Application object or do any excel programming
here. I just construct the csv file and flush it to browser and OS decides to
open this in Excel. I use C#.

Can any of you please throw some suggesstions on this? This is one of our
potential client issue which needs to be addressed fast.
