Hello,

Unfortunately many who create an account here to ask a question never bother to try and comprehend how the site works. When you have signed in you are on the main page. On that page, there, in the right hand column, is a section called Resources. Please take just a minute or two to read How to use the Ask site. It’s not all encompassing but will provide basic information to ask a bit better question than you have.

There are also a few other links at the bottom of the page - FAQ & Help which are often overlooked and contain other information.

new to LibreOffice. Don’t appreciate patronising bastards.

This was posted because you are new and did not provide vital information - OS, specific LO version and more definition on the problem you are having.

No not patronizing but rather trying to help as those links also provide other information on how to use the site. If you think this offensive then my apologies - it is not meant to be.

Also don’t appreciate being called unnecessary name when all I am trying to do is help you get an answer.

I apologise

Thank you, but would most like to know if your problem has been solved. If not please provide additional information such as actual steps taken, files used (ie: type), Specific LO version, OS and any specific error messages.

Hello,

You do not register a spreadsheet. Databases are registered. You can create a database based upon the spreadsheet. See this post → How do I create labels from a spreadsheet?.

Once you have a registered database you can create labels. There are step by step instructions for label printing in the LO documentation. Please see → LibreOffice Writer Guide, Chapter 14 - Mail Merge.
