We had a disastrous accident and deleted an Excel file permanently. We still
have eleven TMP files though in the same folder (with names like RT
ORDERS.xls~RFefb0e6.TMP), and I've retrieved an old archived version of the
original .xls file with records up to March last year.

Is there some way of using the TMP files to restore the data from the
deleted version of the .xls file?

Yes, I just did. Use pandora recovery software to download the .tmp file which in the "modified last" column reports the most recent time stamp. Once you download the .tmp file, use excel to open it by selecting "all files" in the file type drop down. Did the work for me!
