So I stumbled across instructions on how to do this in Excel but
can't get the same result in LibreOffice.

Suggestions appreciated as always
The first formula given at that web page worked for me once I'd
tinkered with the details to fit my actual case. And I needed to
replace commas by semicolons. (The formula as given will not find
instances of zero in the list.)
Note that it is an array formula, so you need to complete it using
Ctrl+Shift+Enter instead of plain Enter. The formula will then show
with {braces} around it in the Input Line (but you cannot achieve
the same result by typing braces yourself).
Note also that it seems that you cannot fill the array formula down
the column by dragging the fill handle. Instead, copy the formula
from the original cell, select all the target cells, and paste.
Oh, and note also that - since the MATCH() function supports regular
expressions - any characters in the data that have special meanings
in regular expressions may upset the operation of this formula unless
you have Tools | Options... | LibreOffice Calc | Calculate | Enable
regular expressions in formulas *unticked*.
