LOTS! if you use excel properly, it will save you hours of calculating by hand...
Electronic spread sheets can easily be modified and/or deleted. A hard copy spreadsheet not so. But if you regularly save your work as you are using the spreadsheet you should not have any problems. There is a way to setup Excel to auto save every few minutes.
Use Save As instead of Save to save a spreadsheet as an HTML table. While the user will be able to view the spreadsheet in a browser, they will not be able to manipulate the contents.
A spreadsheet that you create and save with Excel is an example of a file.
If you don't save it you will lose all your work.
First you need to save it as a webpage, which you can do by using Save As. You will then need access to webspace in order to upload it. You will also need FTP software to do the uploading.

To use the preloaded CelSheet app on the TI-84 calculator, first access the app by pressing the APPS button and selecting CelSheet from the list.

To perform calculations or manipulate data, use the built-in functions available in the app. Finally, you can save your work by following the prompts to save your spreadsheet.
It is not clear what you mean by data capture. You can save the spreadsheet and you will have all your data "captured." If this does not answer your question, please ask again using words that make it clear what you want to know.
Yes. Any time a function recalculates itself, it can make a change to the spreadsheet. If a spreadsheet has changed and you go to close it without saving those changes, then you will be asked to save it. Some functions only recalculate when you change something in the spreadsheet. If your spreadsheet is only using those kinds and you make no changes, then the file can be closed without saving. The NOW function, and some others, will automatically recalculate themselves and change their values where necessary, leading to you being requested to save the file if you haven't already done so. Even if they do request a save, it isn't always necessary to do so, unless you have made other changes to the file yourself.
