Nether Materials
Netherrack, Nether Bricks, Cracked Nether Bricks, Chiseled Nether Bricks, and Ancient Debris each convert into their Pillar version through a stonecutter. Use 
Pillar Nether Bricks for fortress-style columns and 
Pillar Ancient Debris for rare, high-value accent pillars.
End Materials
End Stone, End Stone Bricks, Purpur Block, and Chorus Flower all have Pillar versions. 
Pillar Purpur Block and 
Pillar Chorus Flower are useful for End-themed towers and floating structures. 
Pillar End Stone Bricks make clean, pale columns for endgame builds.
Prismarine
Prismarine, Prismarine Bricks, and Dark Prismarine convert into 
Pillar Prismarine, 
Pillar Prismarine Bricks, and 
Pillar Dark Prismarine. These suit underwater bases and ocean monuments. Pair Pillar Dark Prismarine with Pillar Prismarine for a two-tone column.
Obsidian and Crying Obsidian
Obsidian and Crying Obsidian each have a Pillar version. 
Pillar Obsidian is a durable dark column; 
Pillar Crying Obsidian adds a glowing purple accent for Nether portals and dark ritual builds.
Method
Every conversion uses the stonecutter with the vanilla block as input. Because these materials are often expensive or slow to gather, convert only what you need and keep spare vanilla blocks in a chest near the stonecutter so you can top up mid-build.
