Binary Data

I have exported a card database(600 cards) into excel from a security system to upgrade to a newer card reader system. However, the proper and new card reader system reads the card data in reverse. So I have dumped the data in an excel spreadsheet to sort the data around and import to new system. However, I can not figure out a way to take this data and convert it to the proper numbers. For Example, the card number is 3d88 in hex or 15572 in decimal. I converted it to binary which is 1111010001000, However I need the data to read 0001000101111 so I can convert it to decimal(1135). I only have the binary data, I have no idea what the decimal number is until I convert it. Is there a way to input 0001000101111 into a cell and covert to decimal? When I input it into a cell, it is recognized as 1,0001011,111. Not actual binary data. Or other possibility would be to take the original backwards binary data and convert the value in reverse? If it does not make sense, let me know.

Thanks,

Excel Facts

Which Excel functions can ignore hidden rows?
The SUBTOTAL and AGGREGATE functions ignore hidden rows. AGGREGATE can also exclude error cells and more.
I would advise against responding constructively.

There have been at least two other threads with similar questions, perhaps in the "other" forum. I regret that I contributed to one of those threads. It seems unlikely that 3 different(?) people are doing the same thing ("upgrading to a new card reader system"). Either this is a homework assignment; or I suspect that there is something nefarious going on.
