A Sampling Program

[Miloann]

Is there existing macros or functions that I can perform the following
sampling logic?

I have a file with 500K transactions. Would like to start with a number and
select one transaction every 30 records. The total number of selected
transactions are 2000.

Thanks.

One way ..

Assume txn data is in col A, from A1 down to A65536

In B1 will be input the row start number, say: 3

Put in C1: =OFFSET(INDIRECT("A"&$B$1),ROW(A1)*30-30,)
Copy C1 down to C2000

C1:C2000 will return what's in: A3, A33, A63, ....

Had presumed there was a typo (an extra zero?) in your line50K, not 500K <g>)
