Drop the raw per-attack Attacks report (.xlsx) — not the summary sheet. Every stat the card needs is calculated from it directly. Skip to Step B below if you already have a filled-in war CSV.
Grades and notes are blank in that file — the preview below is just a sanity check. Send the CSV to your faction leader to fill those in, then load the finished file below.
Once grades and notes are filled in (by hand, or from Step A's download), load it here to build the cards.
