I'd like to share this google spreadsheet I created:https://spreadsheets.google.com/spreadsheet/ccc?key=0Amu2Hoiel5SYdFJMVV95cG5pbFppSHc4YnVwUzZwanc&hl=en_US&authkey=CIa_g-AM
I created this spreadsheet because I wanted to keep a secure savings account. For this savings account, I have 12 bitcoin addresses that I use for sending money to. And since I rarely need to take money out of my savings account, I would prefer to keep my wallet.dat file encrypted and not point the bitcoin client to that wallet much. But I still want an easy way to check how much money I have in that account. I figured out that I can use blockexplorer.com to check the balance of each of my 12 bitcoin addresses. So I created this spreadsheet to do the work for me. Now, I will never need to decrypt my savings account wallet file unless I need to send money out of it. I can just use this spreadsheet to make sure that my money is still safe and sound.
This may be helpful for others too, so I made this example spreadsheet. To use it, make a copy of it to your own account. If you want the total balance to be accurate, be sure to copy all your receiving bitcoin addresses into the spreadsheet and create more rows if you need to.
