LibreOffice is a modern heavyweight, formerly OpenOffice. The
CONCATENATE function accepts only single cells as arguments but not
a range of cells. This has always bugged me. To concatenate a range of cells
you must create a macro, which does the work for you. Afterwards you can use
the function across your document. Andrew Pitonyak has written a
nice and profound macro documentation for OpenOffice, which is
available as book too. These docs will also work for LibreOffice.
Likewise, the official documentation is a good starting point.
To create custom macros you need to open a document and execute
Tool > Macros > Organize Macros > LibreOffice Basic from the application
menu. Select your document, create a new module and paste the snippet. Save
the document and close the window. Now you can use
=MyConcat($A1:$A99, "; ")
=MyConcat($A1:$F1) to concatenate a range of cells.
