I don't expect the "copy and paste" idea will work as well as downloading to Quicken or some other application. This goes for you too, W2R. "Type in"? As my daughter would say "What is this 'type in' you speak of?"
I hate Quicken, but it knows that Safeway purchases are groceries, and Chevron purchases are gasoline, and it saves me a lot of work.
Here's one way to handle cash. Go count up all the cash you have in wallets, purses, safes, etc. That's the balance in your "Cash Account." Enter that in as the starting balance.
Whenever you make an ATM withdrawal or receive cash, add it to the Cash Account. Whenever you pay for something with a significant amount of cash, record the transaction as a deduction from the Cash Account.
Periodically repeat the procedure of counting up your cash, and compare that total with the total of the Cash Account. It won't match. If you can think of any major transactions you didn't include, enter those. Otherwise, make an entry for "Miscellaneous Cash Expenditures."
For example, at the end of March you show $520 in your Cash Account, and you only have $200 around the house. You remember that you bought a pet rock on Craigslist for $20, so you enter that, and you enter an amount of $300 for Miscellaneous Cash Expenditures.
