Here is the response I get from the paid version (4o):

=========================
To count all entries in column A across multiple sheets in LibreOffice
Calc, you can use the SUMPRODUCT and COUNTIF functions in combination.
Here's how you can do it:

Step-by-Step Solution:

1. Name Your Sheets: Ensure your sheet names are correct and consistent
with your example (A, B, C, D, ..., W).


2. Insert the Formula in a Cell: Use the following formula in a new cell to
count all non-empty entries in column A across your sheets:

=SUMPRODUCT(COUNTIF(INDIRECT({"A.A:A.A", "B.A:A.A", "C.A:A.A", "D.A:A.A",
"E.A:A.A", "F.A:A.A", "G.A:A.A", "H.A:A.A", "I.A:A.A", "J.A:A.A",
"K.A:A.A", "L.A:A.A", "M.A:A.A", "N.A:A.A", "P.A:A.A", "R.A:A.A",
"S.A:A.A", "T.A:A.A", "V.A:A.A", "W.A:A.A"}), "<>"))


3. Explanation of the Formula:

COUNTIF: Counts non-empty cells in the specified range (column A for each
sheet).

INDIRECT: Dynamically creates references to the ranges in each sheet.

SUMPRODUCT: Adds up the counts for all sheets.



4. Adjust for Different Sheet Names: Replace A, B, C, ..., W with your
actual sheet names if they differ. Ensure all sheet names are enclosed in
quotes and separated by commas within the INDIRECT function.


5. Confirm the Formula: Press Enter, and Calc will return the total count
of non-empty entries in column A across all specified sheets.



Let me know if you need further clarification!
