Each row is a distinct block (including its state, e.g. facing=north) found in the file, with how many exist. Type a replacement in the right-hand box — e.g. minecraft:cobblestone or oak_stairs[facing=east,half=top] — and it will replace every occurrence of that exact block. Leave a box unchanged to leave that block alone.
