I have an excel document that has Time|data1|data2|data3 (| denotes a new column not a delimiter) and I want to create a matlab script where I can input a specific time range in the proper format that matches the excel entry and then have matlab search the spreadsheet for those bounds and copy data from both the time column and data2 columns. How do i do this?

I would read in the xls file with "xlsread" (the whole set of data). Then search the first column of the imported data with the "find" command to extract the portion that interests you (your time range).

I will give that a try, my only concern is that the program will run very slowly since the excel file is huge (30k data rows) and xlsread already takes a noticeable time to read my test file with only 1k rows tops in it. That's why I was hoping only having to copy what I needed was possible.

Maybe you can read the file line by line? Using fopen and then fgetl, you get the current line in text format. You can then check if the current time is within your range and store only those values that meet your criteria.
