Hi,

I have a program that read's data from .csv files and then does
calculations. The csv file is 100 rows x 100 columns, and the data is
integers. There are about 20 different versions of the csv file, all the
same dimensions with different numbers. Right I have to save 20 files and
then "read" each file seperately, but this is cumbersome.

I used to work with APL and you could save a filetype that could store all
the "data" in the arrays. So the file could be an array of
"ArrayOf_Integers[ 20 x 100 x 100]" and you could just read from this
filetype that was recognized by APL. This was convenient because all 20
files of 100x100 could be saved in a single file.

Is there a way to save the .csv files in a single fileformat that can be
then read by the VBA- or are there any other suggestions?

Thanks
