opening a large text or csv file
 

Hi,

I am trying to write a macro where I have to import a large text or CSV
file. The number of rows in the file is something like 805000 (number of
columns if just 2). Obviously excel cannot handle rows greater than
65536.
I want to open 1000 rows at a time and put it in the excel sheet, then
open another 1000 and so on. How can I do this ? Please help. If you
have a better way of doing this please let me know as well. Thanks

Srikanth
