is there anywhere on the net that I can learn about financial spreadsheets?

Answer 1

It depends on what you mean by financial spreadsheets. But, yes, there is a ton of stuff on the web. Just google it.

Answer 2

First start off my understanding all the options on Excel from the Microsoft web site
Then understand add on options, like audit features
Then download samples from Mr Excel, etc
Match the worksheet sample against a valid topic in Finance and understand how it works, how to enter. Learn simple VBA EXcel commands. If you work in Finance you MUST understand what Sarbanes Oxley is!!
Most important, understand that it is very easy to make mistakes in Excel
