FPSpreadsheet where does it go to

[Weiss]

never had to add a library. Readme and FP wiki do not say in clear language how to install library.

I understand this must be some dumb question, but please save me time. It is a second day I am googling it.

I need to learn working with data in spreadsheet "xls" format.

You are asking to use it in FPC or Lazarus?

If you want to use it in FPC look here: https://forum.lazarus.freepascal.org/index.php/topic,62453.msg472320.html#msg472320
