Variable Data Matrices From Excel

I have several spreadsheets from excel that I am trying to get matlab to analyze. The column, in particular, that I am extracting from starts at the same row in each sheet. However, the end of the data varies between sheets. Normally, a (1:end) type of command would fix this, however there are data sets below the wanted range which I do not want included...so really, it would be a (1:variable_ending) type of thing.

What command could I use to select the lowest nonzero value to the highest value as the range for which to extract data from?

Can you provide an example of your column data? I don't quite understand your last phrase.

Any reason you cant read the full column data, and then filter data you need?

what differs the data in the column you want and the data coming right after? are there blank cells? different type of data? if you have, just take the whole column and parse it later.
