Ledger addresses

[rob63]

I'm trying to setup a investment management app/program. Ledger doesn't provide any means to export a file so for transactions already completed I have to manually input them.

When looking at a transaction in ledger wallet and trying to locate my address (it generates a new address for each transaction, but I'm sure you guys know this) I see two addresses in the 'To' section. How do I determine which address it is and why are there two? I thought btc addresses where all the same length, in some transactions it looks like two addresses and one is longer than the other?

When you see 2x "To" addresses, one of them will be a "change address" (https://en.bitcoin.it/wiki/Change)... it is also possible that bitcoin addresses are of different lengths,
 anywhere from 26 to 34 characters (https://en.bitcoin.it/wiki/Address#What.27s_in_an_address)

You might benefit from using the Ledger in conjuction with a wallet like Electrum (https://electrum.org/#download)... it will show you which address is a change address (when you look at the transaction details, receive addresses are highlighted green, change addresses are highlighted in yellow, external addresses are not highlighted)...

There is also some limited export functionality for transaction history, but I believe that it does NOT export the addresses, just transactionID, datetime and amounts.
