[BSU_Data]

I have a data set consisting of six columns and roughly 40,000 rows. I need
to be able to reduce the dataset in size by selecting every 15th row, and
then exporting the values of the 6 columns, ie I need to reduce my 40,000
rows to less than 3,000 and be able to cut and paste the 3,000 rows by six
columns into modelling software. This equal interval filtering seems like
basic data manipulation but I can't figure it in excel. The 40,000 rows have
unique non repeating time stamps (first column).

Thanks!

Put this formula in the first blank column and copy down
=MOD(ROW(),15)
This will put a 0 in row 15,30,45,...

You can filter on 0, copy visible cells and paste to another sheet...

Assume your source data is in Sheet1, in A2:F2 down

In another sheet,
you could place this in any startcell, say in B2:
=OFFSET(Sheet1!A$2,ROWS($1:1)*15-15,)
Copy B2 across by 6 cols to G2, fill down as far as required
to exhaust the source data extract
