I think this is a simple question, but apparently I don't know how to phrase it to the search engines to generate relevant results. I hope that someone here can help or redirect me to the answer.

I have a spreadsheet that was created in Excel Starter on Win7. We would like to share a copy of this spreadsheet with other people, but there are a couple of columns that should be removed before we do that. We want to clear the content of columns J and K without effecting the content in the rest of the spreadsheet. Everything I have tried so far results in all of the data disappearing when J and K are cleared. Please advise.

Thanks!
