If the tool you have is the only way you can process Excel files from your working environment, then it seems like it's not possible to concat them, since they're in binary format, and concatenating them will make the file either unusable to the ETL tool, or it will only read the first file and stop at the first end-of-file indicator.
However, is there any chance that you can get at the output of your ETL app, and concatenate the output of the three files before they're moved on to the next step?
If you can somehow get the XLS files converted to CSV and combine them before processing then you might be able to pull it off -- I'm sure your ETL tool can process a CSV file as an Excel spreadsheet if it can read the XLS format. There are Unix tools that can read XLS and export them as comma-delimited or tab-delimited files, such as the abtab (abstract table) utilities. I used them for two years at my old job.
abtab - Google Code (I don't know how up-to-date the Google Code files are compared to the in-house version I was using, but it should work.)

Hi,
There is this requirement to create multiple work sheets in an MS Excel file through UNIX.
We normally can create one work sheet in unix by either tab or comma delimiting and appending .xls or .csv to the file name, but can we create multiple work sheets.
